Thailand and Indonesia have agreed to jointly advance development of a Plan of Action to translate their strategic partnership into concrete outcomes, and reflect a long-term, forward-looking cooperation framework.

Minister of Foreign Affairs Sihasak Phuangketkeow on 5-6 October 2025 paid a working visit to Jakarta, Indonesia, the first visit of an ASEAN country after the Foreign Minister took office. 

On this occasion, Mr. Sihasak held a bilateral meeting with Mr. Sugiono, Minister of Foreign Affairs of Indonesia, to strengthen bilateral cooperation following the elevation of Thailand-Indonesia relations to a Strategic Partnership during the visit of the President of the Republic of Indonesia to Thailand in May 2025.

Both sides reaffirmed the strategic importance of the close Thailand–Indonesia ties. As founding members of ASEAN and major economies of the region, Thailand and Indonesia will strengthen coordination on key regional issues, according to a report from the Ministry of Foreign Affairs of Thailand.

The Thai and Indonesian foreign ministers also discussed ASEAN’s role in supporting sustainable peace in Myanmar, while Thailand reiterated its commitment to resolving issues with Cambodia peacefully, through existing bilateral mechanisms.

Both sides also agreed to expand economic cooperation, including on agricultural produce, sustainable fisheries, halal industries, energy, tourism, and future industries. Thailand stands ready to host the Joint Trade Committee meeting between Thailand and Indonesia in 2026, in order to increase investments between the two countries. 

The Thai side also requested the Indonesian side to continue to support Thai investors operating in Indonesia.
