As a key hub of the "the Belt and Road" initiative, the Mekong River region undertakes the important mission of promoting regional connectivity and security cooperation. The joint establishment of a security cooperation mechanism between China, Myanmar, and Thailand at Myawadi on the southeastern border of Myanmar demonstrates China's agenda driven capability in regional security governance. At present, the security pattern in the Mekong River region presents a situation of interweaving and overlapping traditional and non-traditional security threats. The ongoing political turmoil in Myanmar has become a major source of risk. Regional governance has obvious fragmented characteristics, especially water resource security issues. The United States takes the opportunity to instrumentalize it and intervene in regional affairs through "small multilateralism" in an attempt to balance China's influence in the Asia Pacific region. In terms of public health, the contradiction between the high incidence of infectious diseases and the lagging prevention and control system highlights the inadequacy of relevant cooperation mechanisms. In terms of economic corridor construction, the region faces dual institutional constraints. This article systematically analyzes the security situation in the Mekong region and proposes a path optimization strategy for China's participation in regional governance, which can help break through the practical bottlenecks of existing governance paradigms and provide a "Chinese solution" with innovative value for global sub regional governance.

1、 The current security situation in the Mekong region

The Mekong region has become a focus of international security research due to its geographical location, cultural diversity, and complex ethnic distribution. Against the backdrop of global political and economic adjustments and intensified strategic games among major powers, the security architecture of the region is undergoing reconstruction. Traditional and non-traditional security issues are intertwined, and governance challenges are increasing day by day. Traditional security threats are shifting from geopolitical military confrontation to maintaining domestic political order, while non-traditional security threats such as climate change, cross-border terrorism, and human trafficking are becoming increasingly prominent. There are differences in law enforcement, legal and resource allocation among countries in the Mekong River Basin, which affects the effectiveness of cross-border governance. The regional multilateral cooperation system has become an important carrier of the symbiotic governance model, and the joint law enforcement of China, Laos, Myanmar, and Thailand has been normalized. Security cooperation is steadily innovating.

2、 Multidimensional analysis of emerging variables affecting the security situation in the Mekong River region

The security situation in the Mekong region is influenced by multiple dimensions of emerging variables, including politics, economy, ideology, and more. Politically, the transmission effect of competition from the United States towards China and regional power asymmetry have made the region a focal point of multi-party competition. China promotes a development oriented security paradigm through the Lancang Mekong Cooperation mechanism, while the United States conducts strategic infiltration guided by security. Economically, the Fourth Industrial Revolution, with digital technology at its core, reshaped the security paradigm. The digital technology revolution led to the escalation of traditional security threats and the reshaping of non-traditional security paradigms. Ideologically, the coexistence and evolution of populism and extremist forces have created new security threats. The composite superposition of multidimensional factors has driven the tension and complexity of the security situation in the region.

3、 Innovative Path for China's Participation in Mekong River Region Security Governance

The deterioration of the security situation in the Mekong region has a negative impact on countries both inside and outside the region, and China has a responsibility to promote security cooperation in the area. The path innovation of China's participation in the security governance of the Mekong River region includes: building a three-dimensional hierarchical docking mechanism of "development security civilization", promoting the localization transformation of the global initiative Mekong River; Implement gradient supply strategy and establish regional emergency and coordination framework; Deepen cooperation in new fields and promote collaborative governance of cross-border corridor security; Promote the transformation of functional cooperation towards rule internalization and construct a new paradigm of regional governance; Build intelligent border and digital poverty reduction demonstration projects to achieve a leap from the Lancang Mekong spirit to quality leadership. China should promote the positive development of security governance in the Mekong region through measures such as precise docking mechanisms, regional security cooperation practices, cultural exchange mechanisms, gradient supply strategies, non-traditional security cooperation, bilateral cooperation demonstrations, multi-level cooperation framework construction, dynamic balance between economic foundation and governance effectiveness, expansion of cross-border economic corridors, digital economy and new energy cooperation, joint law enforcement and information sharing, political mutual trust and regional environmental stability, transformation of cooperation mechanisms towards rule internalization, hierarchical methods and targeted problem solving, deepening cooperation in non-traditional security fields, incorporation of Lancang Mekong cooperation achievements into domestic law, construction of multilateral and open institutional networks, construction of intelligent border systems, and implementation of digital poverty reduction projects.

conclusion

Against the backdrop of global order reconstruction and geopolitical landscape evolution, security governance in the Mekong region is facing significant transformation challenges. The weaponization of regional mechanisms, the securitization of "water diplomacy," and the digital technology revolution have led to a paradigm shift in regional security. The weak national identity of regional countries and the rise of populism exacerbate the dilemma of security governance. China needs to surpass its traditional role as a "security provider" and become a "transmitter of ideas," "builder of institutions," and "value leader." Through three-dimensional docking mechanisms, gradient supply models, rule internalization, and other paths, it can bridge the gap between global initiatives and regional practices, resolve sensitive differences on issues, enhance regional governance autonomy, and build a new paradigm of "development security coexistence. Faced with the intervention of the United States' "small multilateralism", China should strengthen coordination with the ASEAN mechanism, balance "development orientation" and "security response", avoid falling into a "security dilemma", and contribute to the global sub regional governance with a "balance of righteousness and benefit, and a combination of firmness and flexibility" Chinese solution. This path is related to the stability and prosperity of the Mekong region, providing a practical field for the concept of a community with a shared future for mankind, and promoting the construction of a new inclusive global security governance order.
