U.S. Urges Cambodia and Thailand to Uphold Peace Accord, Resume Dialogue

PHNOM PENH, June 17, 2026 (KPT) — The United States has reaffirmed support for peace efforts between Cambodia and Thailand, urging both sides to uphold existing agreements and resolve disputes through bilateral mechanisms, officials said Tuesday.

U.S. Chargé d’Affaires Benjamin Chiang told reporters in Phnom Penh that Washington remains committed to backing the Kuala Lumpur Peace Accords and the December 2025 ceasefire. “Both sides should continue implementing the accords and return to bilateral mechanisms to resolve differences,” he said.

His remarks came amid ongoing diplomatic efforts to ease border tensions following clashes last year that displaced thousands. Minister of Post and Telecommunications Chea Vandeth welcomed U.S. support, praising Washington’s role in facilitating dialogue. He cited President Donald Trump’s involvement in helping secure the ceasefire.

Despite the truce, Cambodia has accused Thailand of violating commitments by maintaining activities in disputed zones. Phnom Penh has lodged protests over construction and cultural projects in Preah Vihear and Oddar Meanchey provinces. The Interior Ministry said more than 28,000 civilians remain displaced six months after the ceasefire.

Cambodia has called for the resumption of joint border surveys and meetings of the Joint Boundary Commission, delayed by Thai political transitions. The State Secretariat of Border Affairs reiterated Cambodia’s commitment to peaceful resolution and rejection of unilateral changes.

U.S. officials said continued implementation of the accords and bilateral dialogue are essential to preserving stability along the frontier.
