The 3rd UMCI Dialogue marked a shift from exchange to action, as cities and partners strengthened a demand-driven regional platform to address shared challenges along the Mekong corridor.
From 3–4 December in Vientiane, Lao PDR, cities, national authorities, and regional partners gathered for the third Urban Mekong Corridor Dialogue, marking a shift in how cities along the Mekong Corridor are jointly addressing rapid urbanisation, rural–urban migration, and climate pressures.
Convened by Cities Alliance, with United Cities and Local Governments Asia-Pacific (UCLG ASPAC) and the Mekong River Commission (MRC), the Dialogue brought together over 90 participants from across the region.
Discussions focused on how migration-driven urban growth is reshaping demand for housing, services, jobs and infrastructure, and how cities can respond in a more coordinated way along the corridor.
The Dialogue forms part of the Urban Mekong Corridor Initiative (UMCI), funded by the Swiss Agency for Development and Cooperation (SDC), which connects city priorities with national and regional frameworks to address challenges that cut across borders.
“Regional initiatives recognise that many transboundary challenges require joint solutions,” said Jean-Gabriel Duss, Regional Director for SDC. “UMCI translates these priorities into the urban context, supporting cities to grow more inclusively and resiliently.”
A regional platform growing in relevance
The third edition of the Dialogue demonstrated how UMCI is evolving from an initial space for exchange into a more structured, demand-driven regional mechanism. All founding cities are now actively engaged, and new cities, including Battambang, Pursat and Vang Vieng, have joined the platform.
Participation has also broadened to include ministries, civil society organisations and regional institutions, reflecting the multi-level nature of urban and migration dynamics along the Mekong.
For the Mekong River Commission, UMCI complements basin-wide planning by strengthening the role of cities in managing the downstream impacts of urban growth and mobility.
Across thematic sessions, cities shared practical experiences on managing rural–urban migration and population inflows, alongside climate adaptation and environmental action. Discussions highlighted how migration intersects with waste management, land use, housing and service delivery, and how city-led planning can help reduce pressure on both urban systems and surrounding ecosystems.
The Dialogue also featured the launch of Strengthening Regional Cooperation on Waste and Plastic Pollution in the Mekong River System, the first joint Cities Alliance–MRC technical publication. The report illustrates how urban waste systems, often under strain from rapid urbanisation and migration, directly influence river health and basin-wide outcomes.
Local leadership and regional cooperation
Civil society organisations played a central role in discussions on migration corridors and social inclusion, particularly in fast-growing cities receiving new residents. The 2025 UMCI Civil Society Awards recognised women-led organisations supporting migrants, informal workers and vulnerable urban communities.
On behalf of the host city, Phouvong Vongkhamsao, Vice Governor of Vientiane Capital, expressed his strong support for the initiative and its objectives. “Vientiane is committed to advancing green and climate-resilient urban development and welcomes regional exchanges through UMCI,” he said.
Building on the momentum from Vientiane, UMCI will continue to strengthen city-to-city and city-to-institution cooperation, support early-stage project preparation, and deepen alignment with regional partners.
As rural–urban migration and urban growth continue to shape the Mekong corridor, the platform will focus on translating shared challenges into coordinated, city-led solutions.
