In a historic breakthrough for Southeast Asian diplomacy, Cambodia and Thailand on Sunday signed the long-awaited “Cambodia–Thailand Peace Accord,” formally ending years of border tensions and military confrontations.

The agreement was signed in Kuala Lumpur in the presence of U.S. President Donald Trump, who played a central role in mediating the deal, and Malaysian Prime Minister Anwar Ibrahim, the current ASEAN Chair. Cambodian Prime Minister Hun Manet and Thai Prime Minister Anutin Charnvirakul represented their respective nations at the ceremony, which was attended by ASEAN officials, diplomats, and international delegates.

President Trump, presiding over the signing, emphasized the power of “economic diplomacy” in maintaining peace. He announced two additional agreements alongside the peace accord — a new U.S.–Cambodia trade deal and a strategic minerals partnership with Thailand. “We do business with both nations, and peace is good for business,” Trump said. “When countries trade and prosper, they don’t go to war.”

Hun Manet praised Trump’s “decisive leadership” and thanked Anwar Ibrahim for hosting the negotiations, calling the accord “a new dawn for Cambodia–Thailand relations.” He stressed that all disputes “must be resolved through peaceful means.”

Thai Prime Minister Anutin Charnvirakul echoed the sentiment, saying the deal “gives our people renewed hope for a stable and prosperous future.” He also expressed gratitude for President Trump’s condolences over the recent passing of Thailand’s Queen Mother.

The peace accord outlines plans for joint border management, security cooperation, and the creation of a bilateral peace commission to ensure compliance and sustain dialogue.
