Kuala Lumpur – July 27, 2025

Leaders from Thailand and Cambodia will meet in Malaysia on Monday, July 28, to engage in peace talks aimed at resolving a seriously escalating border conflict that has claimed dozens of lives and displaced more than 200,000 people. The meeting is being mediated by Malaysia’s Prime Minister Anwar Ibrahim, currently chairing ASEAN. Both governments have requested Malaysia’s involvement and agreed that it was the only third party they would accept, emphasizing the issue as a diplomatic ASEAN matter.

What Led to the Talks?

• The conflict flared up after a Cambodian soldier was killed in late May near Prasat Ta Moan Thom, sparking troop buildups and border tensions.
  

• From July 24, heavy fighting erupted, involving artillery and rocket fire across at least six disputed zones—including near the Preah Vihear and Ta Muen Thom temples. This marks the worst escalation in over a decade.
  

• To date, the joint death toll exceeds 30 mostly civilians and more than 200,000 residents have been evacuated.
  

• Both sides continue to accuse each other of launching unprovoked attacks on civilians and military positions. Thailand has closed all border checkpoints while Cambodia has called for a UN Security Council session.
  

Path to Talks

Malaysia’s Foreign Minister, Mohamad Hasan, confirmed that both nations have agreed in principle to Malaysian mediation. Acting Prime Minister Phumtham Wechayachai of Thailand and Cambodian Prime Minister Hun Manet are both expected to attend in Kuala Lumpur on Monday evening.

Malaysia has also proposed using the Thailand-Cambodia General Border Committee, a mechanism both countries rely on for operational dialogue on such disputes, to draft ceasefire terms and avoid assigning blame.

Although Thailand prefers resolution through bilateral channels, it has indicated willingness to engage regionally given escalating violence. Cambodia welcomed the ceasefire proposal and reiterated calls for international support.

International Stakes

• U.S. President Donald Trump intervened diplomatically threatening to suspend trade negotiations unless both sides agree to ceasefire talks.
  

• ASEAN Chair Malaysia is positioned as the primary mediator, while China and the UN have also called for de-escalation.
  

What to Watch in Malaysia

1. Confirmed attendance by Phumtham Wechayachai and Hun Manet, with talks scheduled to begin at 3 PM local time.
   

2. Terms of troop withdrawal, demilitarized zones, and potential use of the General Border Committee platform.

3. Whether both leaders will publicly endorse a ceasefire, and timing of any joint communique.

The Cambodian Ministry of Defence said the incident occurred on May 28 in an undemarcated area along the shared border, prompting an immediate military buildup on both sides. In a statement, Cambodian officials emphasized the commitment by both countries to “ease tensions” and avoid further escalation.

The announcement follows diplomatic talks led by Thai Defence Minister Phumtham Wechayachai, who said both countries had committed to reverting to 2024-agreed positions to prevent future misunderstandings.

“We are in close communication with our Cambodian counterparts and are committed to maintaining stability along the border,” Phumtham told reporters in Bangkok.

In a show of regional concern, Malaysian Prime Minister Anwar Ibrahim urged both nations to exercise restraint and prioritize dialogue. “Peace and stability in Southeast Asia must remain a collective priority,” Anwar said in a statement.

The contested zone remains a sensitive flashpoint, but analysts say the swift diplomatic response may have prevented a broader crisis.
