Thailand's Deputy PM and Commerce Minister Supachai held talks with US Trade Representative officials in Washington, achieving substantial progress on the Agreement on Reciprocal Trade (ART). Both sides are rushing to finalize technical details before the US announces Section 301 investigation results on structural overcapacity. The US assured Thailand of fair, competitive tariffs. This deal is critical: US is Thailand's #1 export market (worth 2.37 trillion baht) supporting 400,000+ jobs. Thailand has already seen reciprocal tariffs drop from 36% to 19% under IEEPA, then to 10-12.5% under Section 122/301. Closing ART would lock in competitive rates and strengthen investor confidence.
