ERI supports the Mekong Legal Network, an independent group of experienced legal professionals and civil society leaders from the Mekong region that grew out of ERI's Mekong Legal Advocacy Institute (MLAI). Participants in MLN include professionals in Myanmar, Cambodia, China, Laos, Thailand, and Vietnam, as well as other international supporters, who are committed to reducing earth rights abuses. MLN creates a safe space to strategize about regional investments, transboundary legal mechanisms, and Environmental Impact Assessments (EIA) to promote access to justice  in the Mekong region.

The Mekong Legal Network is an invitation-only network that moderates its own membership, and meets approximately twice per year for professional development and sharing of skills and experiences.
