On 28 May 2026, H.E. Mr. Sihasak Phuangketkaew, Deputy Prime Minister and Minister of Foreign Affairs, had discussions with H.E. Mr. Feridun Sinirlioğlu, Secretary-General of the Organization for Security and Co-operation in Europe (OSCE), during the latter’s first visit to Thailand to attend the 2026 OSCE Asian Conference under the theme of “Countering Transnational Threats in the Digital Era Through Enhanced Co-operation in Asia and the OSCE Region,” co-hosted by Thailand and Finland, as a platform for exchanging experiences on approaches to addressing transnational security threats, including combating online scams.

Both sides exchanged views on international and regional security and strategic issues in Europe and the Indo-Pacific, as well as underscored the need to strengthen multilateral mechanisms through international and regional organizations and a rules-based international order in addressing transnational challenges. The OSCE Secretary-General expressed his appreciation to Thailand, as the only ASEAN country that is an Asian Partner for Co-operation of the OSCE, for its outstanding role in promoting dialogues and cooperation between the OSCE and ASEAN, including driving cooperation on security issues of mutual interest, which is crucial in the current highly uncertain international environment.

The OSCE is the world’s largest regional security organization, with over 57 participating States from Europe, North America, and Central Asia. It was established during the Cold War to strengthen the Confidence Building Measures (CBMs) and to serve as a forum for consultation, resolution, prevention, and settlement of disputes and conflicts in Europe. The OSCE's mission focuses on three security dimensions: politico-military; economic and environmental; and the human dimension. Thailand has been one of the five Asian Partners for Co-operation (along with Afghanistan, Australia, Japan, and the Republic of Korea) since 2000 and has played an active role within the OSCE framework.
