The 2025 Investment Treaty Conference is jointly organised by UN Trade and Development (UNCTAD), OECD and the United Nations Commission on International Trade Law (UNCITRAL). The event will address critical developments in international investment agreement policy and practice.

Under the theme “Modernising Investment Treaties to support the Sustainable Development Goals”, the conference will explore avenues for reforming investment treaties, fostering sustainable development, and enhancing global economic resilience.

More

Investment treaties have been used for decades with the aim to encourage and protect foreign investment. While these objectives remain important today, new priorities have emerged: attracting sustainable investment, ensuring a balance between investment protection and policy space, and addressing concerns expressed about the existing ISDS regime such as the lack of consistency, predictability, and transparency of arbitral procedures. In response, treaty-making has undergone substantial change, with the emergence of newer designs that aim to preserve State Parties’ policy space and attract sustainable investment.

However, these changes do not address older treaties with outdated designs that remain in force. International organisations have contributed in different ways to reform efforts through collective action and cooperation. OECD, UNCITRAL and UNCTAD convene this conference to foster discussions among policymakers, stakeholders and experts, explore practical avenues to achieve a pragmatic transition of investment treaties, and accelerate IIA reform.

Programme

The conference will include high-level panels on the following issues:

• Modernising investment treaties: what would be benefits of reform?
• Reforming investment treaties: joint objectives, joint efforts, benefits for all
• A global shift in the design and content of investment treaties: overview of the main recent trends
• How to implement reforms? Practical avenues to achieve a pragmatic transition of investment treaties
