Mekong Region Looks to Cross-Border Cooperation as AI Supercharges Disinformation

Governments, media organizations and civil society groups from the Lancang-Mekong region gathered in Phnom Penh this week to discuss how countries can respond to the growing cross-border spread of false information, including synthetic audio, recycled videos and coordinated online manipulation.

The “Zero Fake News” Mekong forum, hosted by Cambodia’s Ministry of Information on June 2, brought together about 200 participants from Cambodia, China, Myanmar, Vietnam, Laos and other regional partners. The discussions focused on fact-checking cooperation, faster information-sharing and digital literacy as misinformation increasingly moves across languages and borders.

Recent cases have underscored the challenge. In May, a video circulating on X claimed to show a drowning incident at a hotel in Shanghai, but fact-checkers found the footage was actually from Vietnam in 2015. Around the same period, an audio clip purporting to feature Thailand’s prime minister announcing the reopening of border crossings with Cambodia was denied by Thai officials and later identified by forensic tools as likely synthetic.

For countries linked by geography, trade, migration and overlapping media ecosystems, such content can spread quickly before authorities or journalists have time to verify it. Cambodian Information Minister Neth Pheaktra told The Paper that Mekong countries need a joint early-warning mechanism to respond rapidly to false information as it emerges.

At the forum, Cambodia proposed several areas for deeper regional cooperation, including a Lancang-Mekong information integrity network, a regional fact-checking and rapid-response mechanism, public campaigns encouraging people to “verify before sharing,” digital literacy programs for border communities and vulnerable groups, and stronger coordination with online platforms.

Speakers from across the region emphasized that disinformation is no longer only a media problem. It can affect public trust, social stability, crisis response and cross-border relations. Participants called for faster official communication, more professional reporting standards, better training for journalists and content creators, and wider public education on how to identify manipulated images, synthetic audio and unreliable sources.

The forum also reflected a broader global trend. Fact-checking networks already exist in Europe, Latin America and other regions, but Southeast Asia and the Mekong basin face distinct vulnerabilities: rapid mobile internet adoption, uneven media literacy, multilingual information flows and politically sensitive border issues.

Cambodia launched its “Zero Fake News” campaign in March, supported by the Lancang-Mekong Cooperation Special Fund. Cambodian officials said they hope to expand cooperation with China and other regional partners in fact-checking, journalist training and information-sharing.

The message from Phnom Penh was clear: in an era when false content can be produced and translated instantly, national responses are no longer enough. For the Mekong region, fighting disinformation increasingly requires a regional infrastructure built around trust, verification and faster public clarification.
