Legal analysis and countermeasures against transnational telecom fraud under LMC cooperation

This article, using the Lancang-Mekong Cooperation Platform (LMC) as a platform and grounded in the theory of political, legal, and technical multi-dimensional joint governance, employs case analysis to dissect and analyze the spatial diffusion characteristics of transnational telecommunications fraud crimes in the Lancang-Mekong region, the bottlenecks in legal regulatory mechanisms, and the degradation of multilateral coordination performance in legal regulation. It proposes that the Regional Comprehensive Economic Partnership (RCEP)1The proposal for reconstructing the crime governance model based on the legal paradigm, through the analysis of cross-border telecom fraud cases (including data from 2018 to 2025), cross-textual comparison of treaty texts, and the 2025 UN/World Bank assessment of economic losses related to crime, reveals that the Lancang-Mekong countries experience overlapping judicial jurisdictions (Jurisdictional Overlap Index: 0.67), with an average delay of 187 days in the cross-border retrieval of electronic data, and asymmetric allocation of cross-border law enforcement resources (Technical Assistance Level Difference: 83%). Through the ASEAN Security Academys simulation experiment on collaborative crime governance, a joint solution has been developed, including a legal coordination module (draft text of the Lancang-Mekong Anti-Telecom Fraud Agreement), a technology integration module (blockchain-based cross-border evidence collection technology for telecom fraud), and a value balance module (evaluation model for the revenue chain in telecom fraud cases). This solution addresses the issues faced by the governance of transnational telecom fraud in the Lancang-Mekong region, reducing the average response time for cross-border law enforcement by 41% and the time required for criminal regeneration by 29% compared to the initial values.
