Thailand's Deputy PM Suphajee met with US Trade Representative Jamieson Greer in Washington on Sept 1, 2025, reaching substantive agreement on the Agreement on Reciprocal Trade (ART). Only technical details remain. The US assured Thailand of fair, competitive tariff rates before announcing its Section 301 investigation results on structural overcapacity. Thailand's US exports worth 2.37 trillion baht employ ~400,000 workers domestically. The deal addresses non-tariff barriers, digital trade, and commercial opportunities, protecting Thai competitiveness against region-wide competitors.
