ADB and ADB Institute Conduct Policy Dialogue on Institutionalizing Mediation and Strengthening ISDS Management Systems

ADB's Law and Policy Reform Program and ADB Institute convened the Second Alternative Dispute Resolution Policy Dialogue, focusing on institutionalizing mediation and strengthening investor-state dispute settlement management system on April 20-22, 2026 in Tokyo.

This policy dialogue responds to the growing need among ADB developing member countries to strengthen their capacity to prevent and manage investment disputes while promoting practical dispute resolution tools.

Building on the First Alternative Dispute Resolution Policy Dialogue held in February 2025, which focused on raising awareness of mediation and the Singapore Convention on Mediation, the second policy dialogue marks a shift from awareness-raising to implementation. It aims to take stock of progress to date, review evolving policy directions, and support countries in translating principles into concrete institutional arrangements and policy frameworks.

As foreign investment continues to expand across Asia and the Pacific, countries’ exposure to investor-state disputes has increased. Many developing economies face constraints in managing investor-state dispute settlement (ISDS) processes, resulting in significant legal costs, fiscal pressures, and reputational risks. Addressing these challenges requires targeted policy engagement and strengthened national ISDS management systems.

In parallel, in recognition of the Association of Southeast Asian Nations (ASEAN) as a dynamic region with a growing volume of investment in infrastructure, energy, and green and digital transitions, a dedicated exchange tailored to ASEAN member states was convened alongside the policy dialogue to facilitate a more focused and applied engagement.

The event was opened by the ADB Institute Dean and ADB General Counsel and brought together more than 20 ADB members, regional bodies, judges, ADR institutions, and development partners.
