On 28 December 2024, Thailand was informed by Russia, Chair of BRICS for 2024, confirming that Thailand will join BRICS as a Partner Country starting from 1 January 2025.

Thailand's partnership with BRICS builds on its longstanding cooperation with the group, which began in 2017 when Thailand joined the BRICS Plus mechanism. This partnership offers significant opportunities to strengthen economic ties with BRICS member countries - emerging markets and developing countries with high growth potential. Key areas of collaboration include trade, investment, and tourism. In addition, the partnership also fosters people-to-people ties between Thailand and other BRICS members and partners. Beyond economic cooperation, Thailand’s engagement with BRICS reinforces its commitment to multilateralism, particularly among developing countries. Thailand also expresses its readiness to be the bridge builder between BRICS and other regional groupings, such as ASEAN, APEC, ACD, and BIMSTEC.

BRICS currently consists of nine member countries: Brazil, Russia, India, China, South Africa, Ethiopia, the United Arab Emirates, Egypt, and Iran. With Brazil assuming as the BRICS chair in 2025, Thailand, as a Partner Country, will have the opportunity to participate in some meetings which can support the collaboration under BRICS framework.
