The methodological framework for studying the transformation of cross-border legal regulation in the context of digital sovereignty must recognize the nonlinear nature of the modern legal order, in which the classical territorial binding of jurisdiction is giving way to a multi-layered, networked regulatory architecture mediated by digital platforms, transnational data flows, and algorithmic decision-making systems. In this regard, the fundamental principle is the integration of comparative legal, institutional, and functional approaches, allowing us to identify not only the formal differences between the legal regimes of the Russian Federation and the People's Republic of China but also their underlying regulatory logic, shaped by digital sovereignty and national security strategies.

The comparative legal method in this context acquires particular depth, as it requires a comparison not only of regulatory acts but also of law enforcement models, including judicial practice, administrative regulatory mechanisms, and quasi-legal instruments developed by the state through technological standards and platform requirements. In the Russian Federation, this logic is implemented through the concept of a «sovereign internet», enshrined in federal legislation, including Federal Law No. 90-FZ, as well as through the development of the institution of personal data localization and strengthened control over the cross-border transfer of information. In the People's Republic of China, a similar methodological framework is institutionalized in the Cybersecurity Law, the Personal Information Protection Law (PIPL), and the Data Security Law, forming a holistic model of «cyber sovereignty», where the state acts as the central coordinator of the digital space.

Functional analysis allows us to move beyond the formal-legal comparison and consider law as a tool for managing digital flows, where the key object of regulation is not the subject, but rather data—its movement, processing, and use. In this sense, cross-border legal regulation is being transformed into a system for controlling digital value chains that involve platform ecosystems, cloud infrastructures, and algorithmic interfaces. Methodologically, this requires the application of the concept of "regulatory nodes," where law, technology, and the market intersect to form hybrid governance mechanisms that include both mandatory norms and voluntary standards, technical protocols, and corporate policies.

An institutional approach focused on analyzing the constituent entities of cross-border relations is particularly important. Under conditions of digital sovereignty, the state ceases to be the sole bearer of regulatory authority, delegating some functions to large technology corporations, which become quasi-sovereign actors capable of independently establishing data access rules, content moderation algorithms, and the conditions of cross-border interaction. In the Russian Federation, this trend is manifested through the state's interaction with national IT companies and the development of mechanisms for mandatory interaction with government agencies, including data storage and provision. In China, this model has been taken to the systemic level through the integration of private platforms into the state governance system, where companies such as Alibaba, Tencent, and Huawei operate within a tightly coordinated regulatory framework.

The application of the concept of extraterritoriality as a tool for extending national jurisdiction beyond the physical territory of a state is also methodologically significant. This study examines extraterritoriality not only as a legal mechanism but also as a political and economic strategy aimed at ensuring control over transnational digital processes. In Russian practice, this is reflected in attempts to extend national requirements to foreign companies working with Russian users, including requirements for data localization and compliance with national legislation. In the Chinese model, extraterritoriality takes on a more comprehensive nature, including obligations for foreign companies to comply with Chinese standards when working with Chinese data, as well as restrictions on data transfer abroad.

A systems approach allows for the integration of these methods into a single analytical model, where cross-border legal regulation is viewed as a dynamic system subject to constant adaptation in response to technological change. Feedback mechanisms play a key role in this system, ensuring the adjustment of regulatory parameters based on their application and changes in the external environment. The research methodology must take into account the cyclical nature of legal regulation, where each new stage of digital technology development triggers a revision of existing legal frameworks and the development of new law enforcement tools. An important element of the methodological framework is also an analysis of the risks and uncertainties associated with the use of artificial intelligence and algorithmic systems. An interdisciplinary approach, incorporating elements of legal informatics, systems theory, and economic analysis of law, is employed to assess the impact of algorithmic decisions on the distribution of liability, the evidentiary base, and dispute resolution mechanisms. In the Russian Federation, this area is in its infancy, including the development of concepts for regulating artificial intelligence and experimental legal regimes. In China, however, more advanced institutionalization is observed, including mandatory requirements for recommendation algorithms, transparency, and the manageability of AI systems.

The methodology for studying the transformation of cross-border legal regulation in the context of digital sovereignty represents a comprehensive, multi-layered system combining comparative legal, functional, institutional, and systemic approaches, complemented by an analysis of extraterritoriality and algorithmic risks. It aims to identify underlying patterns in the evolution of legal regimes in the context of digitalization, as well as to form a theoretical basis for developing new law enforcement mechanisms capable of ensuring a balance between national sovereignty and the global connectivity of the digital space. Analyzing the transformation of cross-border legal regulation in the context of digital sovereignty requires going beyond the traditional description of norms and exploring the hidden structures of power emerging at the intersection of law, technology, and geoeconomics. The current conflict of jurisdictions in the digital environment is not so much legal as systemic in nature, reflecting competing data governance models, where the state seeks to consolidate control over digital flows, while global platforms seek to preserve the autonomy of transnational operation. This configuration gives rise to the phenomenon of «layered jurisdiction», in which the same data transaction is simultaneously subject to multiple legal regimes, creating a conflict not only of norms but also of law enforcement principles.

In the Russian model, this conflict manifests itself through increased regulatory control over internet infrastructure and user data, which is reflected in the institutionalization of localization requirements, mandatory interaction with government agencies, and the creation of traffic filtering mechanisms. However, the key problem lies not in the regulation itself, but in its asymmetry with transnational platforms, which enjoy a significantly higher level of technological and economic autonomy. This leads to a situation where the state is forced to apply extraterritorial measures, including fines, access restrictions, and enforcement of national legislation. However, the effectiveness of these tools is limited by the potential for circumvention and fragmentation of digital services.

The Chinese model demonstrates a different type of analytical framework, where jurisdictional conflicts are minimized through the pre-integration of platforms into the state governance system. Here, a vertically integrated architecture of digital sovereignty is being formed, in which the state not only sets rules but also controls key points of digital infrastructure, including cloud services, payment systems, and platform ecosystems. This allows China to develop its own regulatory standards, which are then applied extraterritorially to foreign companies operating in the Chinese market, rather than responding to cross-border challenges.

The difference in approaches to the extraterritoriality of norms is analytically significant. In Russian practice, extraterritoriality is reactive and aimed at protecting the domestic market and users, whereas in the Chinese model, it takes on a proactive nature, becoming a tool for expanding regulatory influence. This is manifested, in particular, in requirements for cross-border data transfer, where China introduces mandatory security assessment and approval procedures, effectively establishing control over global information flows related to its jurisdiction.

Particular attention should be paid to the role of platform ecosystems as new centers of regulatory power. Large tech companies are creating their own rules of engagement, which are quasi-legal in nature but effectively determine the conditions of access to markets, data, and users.

In the context of digital sovereignty, a dual situation arises: on the one hand, states seek to subject platforms to their regulation, while on the other, they themselves are forced to respect their regulatory autonomy. In Russia, this is expressed in attempts to institutionalize interactions with platforms through obligations to store and provide data, while in China, platforms are effectively integrated into the state governance system and act as regulatory agents. An analysis of artificial intelligence as an element of law enforcement reveals a fundamentally new problem: the shift in decision-making power from humans to algorithms. This transforms not only the enforcement mechanism but also the very nature of legal liability. When decisions are made based on machine learning, the question of the distribution of responsibility between the developer, operator, and user of the system arises. In the Russian legal system, this issue has not yet been fully resolved, creating a zone of legal uncertainty. In China, however, a more stringent approach is being observed, requiring mandatory identification and monitoring of algorithms, including requirements for their transparency and manageability.

Analysis shows that the transformation of cross-border regulation is accompanied by the emergence of a new type of legal space—fragmented yet interconnected. Instead of a unified global legal order, a network of regional regulatory clusters is emerging, each seeking to establish its own rules of the game. In this context, Russia and China act as hubs of alternative regulatory models opposed to the Western liberal paradigm. This leads to increased legal polycentricity, where international law gradually loses its universal character and is transformed into a set of competing regimes.

The economic aspect of this transformation lies in the redistribution of value within global data chains. Control over data is becoming a key factor in competitiveness, and legal regulation is the instrument for ensuring it. In this logic, digital sovereignty acquires not only political but also economic significance, allowing states to shape their own digital markets and protect them from external influence. However, such a strategy is fraught with the risk of isolation and reduced efficiency of cross-border interactions, which is particularly relevant for Russia, where dependence on global technologies remains significant. From a legal theory perspective, a shift is being observed from normative to procedural regulation, where the mechanisms for implementing them, rather than the rules themselves, are becoming more important. This is reflected in the development of monitoring, control, and automated law enforcement systems, including the use of artificial intelligence to analyze data and identify violations. In China, such systems are already functioning at the systemic level, incorporating elements of social credit and digital surveillance. In Russia, similar mechanisms are still in their infancy, but their development is inevitable in the context of digitalization.

Ultimately, the analytical picture of the transformation of cross-border legal regulation in the context of digital sovereignty represents a complex, multidimensional system in which legal, technological, and economic factors are intertwined. Jurisdictional conflicts, the extraterritoriality of norms, and the development of new law enforcement mechanisms are not isolated phenomena, but interconnected elements of a single process aimed at redefining the boundaries of power in the digital space. Russia and China, pursuing different, but in some respects similar, strategies, are developing alternative regulatory models that could potentially become the basis for a new type of international legal order based on the principles of digital sovereignty and regional regulatory autonomy.

International practice of cross-border legal regulation in the context of digital sovereignty demonstrates a gradual shift from a universalist model of international law to a plurality of competing regulatory regimes, each seeking to institutionalize its own standards for handling data, digital platforms, and algorithmic systems. In this context, Russia and China are not developing isolated legal constructs, but rather elements of a broader Eurasian regulatory model focused on the priority of state control, strategic autonomy, and managed integration into the global digital economy. The practice of the People's Republic of China within the framework of the Belt and Road Initiative represents one of the most illustrative examples of the transnationalization of a national legal regime. China is not limiting itself to domestic regulation, but is actively exporting its own digital governance standards through infrastructure projects, digital cooperation agreements, and the implementation of technological solutions developed by Chinese companies. As a result, a unique "extraterritorial zone of Chinese digital law" is emerging, in which norms on cybersecurity, data protection, and algorithmic control are effectively applied beyond the borders of the national territory. Experience shows that partner countries involved in Chinese digital projects are gradually adapting their legislation to Chinese requirements, indicating a high degree of regulatory influence.

Russian practice, in turn, is developing within the Eurasian Economic Union, where attempts are being made to harmonize digital legislation, including issues of cross-border data transfer, e-commerce, and digital identification. However, unlike the Chinese model, the Russian strategy is more coordinated and faces institutional limitations due to the differences in the legal systems of the member states. Nevertheless, the development of common standards within the EAEU, including uniform approaches to data protection and digital infrastructure, demonstrates a desire to create a regional legal space capable of competing with other global regimes. A comparative analysis of cross-border dispute resolution practices shows that traditional international arbitration mechanisms are gradually losing their effectiveness in the face of digitalization. This is because many disputes arise in areas where there is no clear territorial connection, and the parties interact through platform interfaces distributed across various jurisdictions. In response, new mechanisms are emerging, including specialized online courts, as implemented in China, where judicial bodies have adapted to address digital disputes using electronic evidence, blockchain-based records, and algorithmic decision support. Russian practice is also moving in this direction, including the development of e-justice and the introduction of digital tools into the judicial system, but the level of institutionalization remains lower.

The regulatory practices of transnational platforms demonstrate the differences in the strategies of interaction between the state and business. In China, the state acts as an active regulator and coordinator, imposing strict requirements on platforms, including obligations to store data, disclose algorithms, and ensure compliance with state priorities. In Russia, interactions are more flexible, but in recent years, increased oversight has been observed, including the introduction of requirements for foreign IT companies to establish a legal presence, store data, and interact with regulators. In both cases, a trend toward the "nationalization" of digital platforms is emerging, with market access being restricted to compliance with national regulations. International practices also show that artificial intelligence regulation is becoming a key element of the cross-border legal order. China is actively implementing mandatory standards for algorithms, including requirements for their transparency, non-discrimination, and manageability, effectively creating a regulatory framework for the global AI market. Russia, meanwhile, is developing experimental legal regimes and strategic documents aimed at stimulating the development of AI while simultaneously ensuring oversight of its use. Experience shows that countries capable of integrating legal regulation and technological development gain a significant advantage in global competition. Conclusions from an analysis of international practice indicate that effective cross-border regulation in the context of digital sovereignty requires a combination of three key elements: institutional coherence, technological competence, and regulatory flexibility. Russia and China demonstrate different combinations of these factors, which determines their positions in the global digital legal system. The Chinese model is characterized by a high degree of integration and proactivity, while the Russian model is more adaptable and seeks a balance between sovereignty and openness. Recommendations from the analysis suggest the need for further institutionalization of cross-border cooperation in digital law, including the development of bilateral and multilateral agreements aimed at harmonizing data protection standards, information exchange, and platform regulation. For the Russian Federation, strengthening coordination within the EAEU and developing mechanisms for the international recognition of digital solutions is essential. For the People's Republic of China, further development of the export model of digital regulation, taking into account the need to ensure trust with international partners, is essential.

Particular attention should be given to the creation of cross-border dispute resolution mechanisms adapted to the digital environment, including the development of online arbitration, the use of blockchain technology for evidence recording, and the integration of artificial intelligence into judicial practice. Furthermore, it is necessary to develop unified approaches to regulating algorithmic systems, including establishing standards of transparency, accountability, and ethics, which will minimize the risks associated with their use. International practice confirms that the transformation of cross-border legal regulation in the context of digital sovereignty is an irreversible process that requires a rethinking of traditional legal approaches and the development of new mechanisms for interaction between states, businesses, and society. Russia and China, possessing significant potential in this area, are capable not only of adapting to ongoing changes but also of actively participating in the formation of a new digital legal order based on the principles of sovereignty, security, and technological sustainability.

Understanding the transformation of cross-border legal regulation in the context of digital sovereignty requires identifying elements that remain outside of direct normative analysis but exert a decisive influence on the evolution of the legal order. First and foremost, it must be acknowledged that the modern legal system has entered a phase of structural restructuring, where the law is losing its monopoly on regulating social relations, ceding some of its functions to technological architectures, algorithms, and infrastructure solutions. This means that the boundaries of legal influence are shifting from the level of formal rulemaking to the level of designing digital systems, in which norms are «embedded» in code and become part of the technological environment. In this context, digital sovereignty should be viewed not only as a legal category but also as the state's ability to control the architecture of digital space, including data transfer standards, interaction protocols, and information processing algorithms.

An unspoken, yet fundamentally important, aspect remains the issue of trust as a fundamental aspect of cross-border interaction. With the fragmentation of legal regimes and the strengthening of states' extraterritorial claims, a trust deficit is developing between participants in digital exchange, leading to increased transaction costs and a decline in the effectiveness of international cooperation. Russia and China, in implementing digital sovereignty strategies, are faced with the need to balance control and openness, as excessive regulation can limit access to global markets and technologies, while insufficient control can undermine national security and economic stability. Thus, the key challenge is developing legal and institutional mechanisms that ensure regulatory predictability and transparency without sacrificing sovereign control.

The transformation of the very category of liability in the context of algorithmic law enforcement deserves special attention. The traditional model, based on the individual fault of the subject, is proving insufficient to describe situations where decisions are made within complex digital systems with distributed architectures. This necessitates a transition to a model of distributed liability, encompassing developers, operators, data owners, and users, which requires a revision of the fundamental principles of civil and administrative law. In the Russian legal system, this process is only just beginning, while in Chinese practice, elements of such a model are already emerging, including obligations to monitor and audit algorithms. No less significant is the question of the future of international law in the context of digital sovereignty. The observed trend toward regionalization and fragmentation of legal regimes calls into question the possibility of preserving universal norms regulating cross-border relations. Instead, a polycentric system is emerging, in which various legal centers—including Russia and China—are developing their own standards and mechanisms for interaction. In this system, international law is transformed from a source of universal rules into a platform for coordinating interests between competing regimes, which requires the development of new forms of legal dialogue and coordination.

It should be noted that the transformation of cross-border legal regulation in the context of digital sovereignty is not a temporary phenomenon, but a long-term trend shaping the development of legal systems in the 21st century. Jurisdictional conflicts, extraterritorial norms, and the emergence of new law enforcement mechanisms are manifestations of a deeper process—the redistribution of power in the global digital space. Russia and China, implementing their own regulatory models, are demonstrating different ways of adapting to these changes, but in both cases, there is a clear desire to strengthen control over data and digital infrastructure.

The key conclusion is that effective legal regulation in the digital age is impossible without the integration of legal, technological, and institutional solutions. States capable of achieving such integration gain a strategic advantage, enabling them not only to protect their interests but also to shape the rules of global interaction. In this regard, the Russian Federation sees a pressing need to further develop its regulatory framework aimed at ensuring digital sovereignty, while simultaneously expanding international cooperation and adapting best practices. For the People's Republic of China, this means strengthening trust in its regulatory model and integrating it into global processes, taking into account the interests of the international community.

Prospects for the further development of cross-border legal regulation are linked to the emergence of hybrid models that combine elements of national sovereignty and international cooperation. Such models entail the creation of mechanisms for mutual recognition of norms, joint regulation, and coordinated enforcement, which will reduce conflict and improve the effectiveness of global governance of digital processes. Otherwise, there is a risk of deepening legal fragmentation and the formation of isolated digital spaces, which will negatively impact the development of the global economy and international relations. The study confirms that digital sovereignty is becoming a key factor in the transformation of legal systems, determining not only the content of norms but also the architecture of law enforcement. In the context of rapid technological development, law must not only respond to changes but also anticipate them, creating conditions for the sustainable and secure functioning of a digital society. This is precisely the strategic objective of modern legal regulation, the successful resolution of which determines the future of the global legal order. Let's examine some cases and draw conclusions.

Case 1. Mandatory data localization and conflicting extraterritorial requirements: Russian practices in interacting with global platforms in the context of personal data demonstrate a persistent conflict between national regulations and the transnational architecture of digital services. The most illustrative line of enforcement is related to the requirement to store the personal data of Russian users within the Russian Federation and to ensure access to such data by government agencies. The practice of holding foreign companies liable for non-compliance with these requirements has revealed a systemic contradiction: platforms operating on distributed cloud infrastructures cannot fully comply with localization requirements without significantly transforming their business model. As a result, a hybrid enforcement model is emerging, including administrative sanctions, access restrictions, and negotiation mechanisms aimed at achieving partial compliance. The key conclusion is that data localization in the context of global platforms is not a purely legal instrument but requires a technological restructuring of the infrastructure, which limits its effectiveness in the absence of international coordination.

Case 2. China's Cross-Border Data Transfer System and "Security Assessment" Mechanism: China has developed a multi-tiered model for controlling cross-border data flows, based on a mandatory state security assessment procedure for the transfer of certain categories of information abroad. Practical implementation of this model has demonstrated that it serves not only a protective but also a selective function, allowing the state to manage digital interactions and limit the leakage of strategically significant data. In corporate practice, this has led to the creation of specialized data management units, the implementation of information classification systems, and the development of internal procedures for coordinating cross-border transactions. A distinctive feature of this case is that the Chinese model goes beyond prohibitions and creates an institutional infrastructure for managed data transfer, including standardized procedures and digital control tools. This helps ensure a balance between economic openness and the protection of national interests.

Case 3. China's Internet Courts as a Tool for Digital Law Enforcement: The creation of specialized internet courts in the cities of Hangzhou, Beijing, and Guangzhou has become one of the most innovative elements of the Chinese legal system. These courts hear disputes arising in the digital environment, including e-commerce, intellectual property, and online contracts, using a fully digital process, from the filing of a claim to the rendering of a decision. Practice has demonstrated the high efficiency of this mechanism, including reduced case processing times and lower transaction costs. Of particular importance is the use of blockchain technology for the recording of evidence and the application of algorithms for the analysis of judicial practice. As a result, a new model of justice is emerging, in which technological tools are becoming systemically important rather than auxiliary elements. This case demonstrates the possibility of integrating artificial intelligence into the judicial system while maintaining formal state control.

Case 4. The Extraterritorial Impact of Chinese Law on Foreign Companies: The application of Chinese personal information protection and data security regulations to foreign companies working with Chinese users illustrates the proactive nature of extraterritoriality. Companies without a physical presence in China but processing the data of Chinese citizens are required to comply with national legislation, including appointing representatives, conducting impact assessments, and ensuring that their algorithms comply with established standards. As a result, foreign companies are forced to adapt their internal processes, effectively extending Chinese legal norms to the global level. This case demonstrates how extraterritoriality is becoming a tool not only for protection but also for expansion of the legal regime.

Case 5. Russian practice of regulating foreign IT companies and institutionalizing "landing": the introduction of requirements for foreign digital platforms to establish a legal presence in the Russian Federation has become an important stage in the development of a national model of digital sovereignty. The implementation of these requirements has demonstrated that the state is striving to move from reactive measures to institutionalized interaction with platforms, including the creation of ongoing monitoring and communication mechanisms. Companies interested in maintaining access to the Russian market are forced to adapt, including opening representative offices, registering in national registries, and complying with requirements for interaction with users and government agencies. However, the effectiveness of this mechanism is limited by the possibility of partial enforcement and the persistent asymmetry of resources between the state and global platforms.

Case 6. Integrating platform ecosystems into public administration in China: Chinese practice demonstrates a unique model in which large technology companies act as regulatory agents, ensuring the implementation of public policy in the digital environment. Platforms participate in data collection and processing, implementing control mechanisms, and ensuring regulatory compliance. This allows the state to significantly expand its capacity to manage the digital space without directly increasing its administrative apparatus. However, this model requires a high level of coordination and trust between the state and business, as well as clear mechanisms for assigning responsibility.

Case 7. Cross-border e-commerce disputes and the limitations of traditional arbitration: The practice of resolving disputes arising within transnational e-commerce platforms demonstrates that traditional international arbitration mechanisms are not always able to effectively address the specifics of digital relations. In response, platforms are developing their own dispute resolution systems based on internal rules and algorithms. In China, such systems are integrated with state mechanisms, while in Russia they function primarily as private initiatives. This case demonstrates the emergence of a parallel law enforcement system, where the boundaries between law and corporate regulation are becoming blurred.

Case 8. Regulating Recommendation Algorithms and Combating Information Risks: The Chinese practice of introducing mandatory requirements for recommendation algorithms, including the requirement to register them, disclose their operating principles, and ensure non-discrimination, is one of the first examples of systemic regulation of artificial intelligence. The practical implementation of these requirements has demonstrated that the state is capable of influencing the algorithmic environment, creating conditions for its manageability and predictability. Similar mechanisms are still being developed in Russia, but a trend toward developing normative approaches to regulating AI is already evident. This case confirms that algorithms are becoming subject to legal regulation on par with traditional legal entities and objects.

The combined case studies allow us to conclude that the transformation of cross-border legal regulation in the context of digital sovereignty is being realized through specific practices in which law, technology, and policy form a unified system. Russia and China, using various tools and approaches, are developing sustainable regulatory models capable of adapting to the challenges of the digital age. However, their further development will depend on their ability to integrate national interests with the demands of global interaction. In conclusion, it is necessary to acknowledge that the transformation of cross-border legal regulation in the context of digital sovereignty represents a systemic shift in the nature of the international legal order, affecting its institutional foundations, law enforcement mechanisms, and the very logic of power distribution in global space. An analysis of theoretical constructs, the practices of the Russian Federation and the People's Republic of China, and empirical cases allows us to assert that modern law has entered a phase of profound adaptation to the digital environment, in which traditional categories of territory, jurisdiction, and sovereignty are acquiring new meaning.

The first key conclusion is that jurisdictional conflict in the digital age is not temporary but structural. It is caused by a misalignment of national data regulation strategies and platform ecosystems, leading to the formation of multiple, partially overlapping legal regimes. The Russian and Chinese models demonstrate different ways of managing this conflict: from reactive strengthening of control and extraterritorial influence to proactively developing an integrated digital governance architecture. However, neither model eliminates the conflict entirely, but rather transforms it into a manageable form. The second conclusion relates to the rethinking of extraterritoriality as a key instrument of modern legal regulation. Extraterritorial norms are no longer the exception, but are becoming a routine mechanism for expanding jurisdiction, aimed at controlling cross-border data flows and the activities of digital platforms. In Chinese practice, this instrument is used systematically and strategically, ensuring the export of national standards, while in Russian practice it is used primarily to protect the domestic market and users. This difference determines the degree of influence of the respective legal regimes at the global level. The third conclusion reflects the transformation of law enforcement mechanisms under the influence of technological factors. A new model is emerging in which law is implemented not only through state institutions but also through digital infrastructures, algorithms, and platform rules. The Chinese practice of online courts and algorithmic regulation demonstrates a high level of integration of technology into law enforcement, while the Russian system is actively developing in this direction. The general trend is a shift toward automated and hybrid forms of law enforcement, where the human factor is supplemented, and in some cases, replaced, by technological solutions.

The fourth conclusion concerns the changing subject structure of legal regulation. Along with states and international organizations, transnational technology corporations, which possess significant regulatory potential, are beginning to play a key role. Their rules and standards effectively form a parallel regulatory system that interacts with national law. Under conditions of digital sovereignty, states seek to limit this autonomy, but it is impossible to completely eliminate it, requiring the development of mechanisms for coordination and joint governance. The fifth conclusion concerns the economic dimension of the transformation. Control over data and digital infrastructure is becoming a strategic resource, and legal regulation is becoming a tool for ensuring it. Russia and China, by implementing models of digital sovereignty, are striving to create conditions for the development of their own digital markets and reduce dependence on external technologies. However, such a strategy carries the risk of fragmenting the global digital space and reducing the effectiveness of cross-border interactions. The sixth conclusion concerns the prospects for the development of international law. The observed trend toward polycentricity and regionalization indicates a gradual shift away from a universalist model in favor of a system based on the interaction of multiple normative centers. In this system, Russia and China act as proponents of alternative legal paradigms oriented toward the priority of state sovereignty and the governance of the digital environment. This requires the development of new forms of international cooperation based on mutual recognition and coordination, rather than unification.

In summary, digital sovereignty is becoming a defining factor in the transformation of legal systems, shaping a new architecture of cross-border regulation. The effectiveness of this architecture will depend on the ability of states to integrate legal, technological, and institutional solutions, ensuring a balance between control and openness. For the Russian Federation, the priority is strengthening the regulatory framework and developing international cooperation within regional associations. For the People's Republic of China, this is the further improvement of the export regulatory model and increasing the level of trust in it among the international community. Prospects for further research include an in-depth analysis of the mechanisms of interaction between government and corporate regulators, the development of models of distributed responsibility in the context of artificial intelligence, and the study of the impact of digital technologies on the evolution of international law as a system. In the context of accelerating digitalization, these areas will determine the content and dynamics of legal regulation, forming the basis for a new stage in the development of the global legal order.

The methodological design of a study of the legal framework for transnational infrastructure projects in the context of the intersection of the Belt and Road Initiative and Eurasian integration requires a synthesis of several complementary approaches to adequately reflect the complex nature of legal regimes emerging at the intersection of national, international public, and private law. The fundamental approach is an institutional and legal one, focused on identifying the architecture of regulatory bodies and mechanisms, including national regulators, interstate coordination structures, and specialized arbitration and quasi-judicial institutions.
