Foreign relations of Thailand

The foreign relations of Thailand are handled by the Ministry of Foreign Affairs of Thailand.

Thailand participates fully in international and regional organizations. It has developed close ties with other ASEAN members—Indonesia, Malaysia, the Philippines, Singapore, Brunei, Laos,and Vietnam—whose foreign and economic ministers hold annual meetings. Regional cooperation is progressing in economic, trade, banking, political, and cultural matters. In 2003, Thailand served as APEC host. Dr. Supachai Panitchpakdi, the former Deputy Prime Minister of Thailand, served as Secretary-General of the United Nations Conference on Trade and Development (UNCTAD) from 2005 until 31 August 2013. In 2005 Thailand attended the inaugural East Asia Summit.

Since the military coup of May 2014, Thailand's global reputation has plunged, according to Professor Thitinan Pongsudhirak of Chulalongkorn University. He maintains that, "When the fourth anniversary of Thailand's coup comes to pass later this month [May 2018], Thailand's foreign relations will be one of the many costs to be counted from the military government....Instead of moving ahead in its relations with the outside world, Thailand has regressed to a standstill.
