Since late May, Thailand and Cambodia have periodically clashed along their border, especially in Chong Bok, between Ubon Ratchathani (Thailand) and Preah Vihear (Cambodia). These clashes have affected trade and travel in border provinces, including Surin, Si Sa Ket, Banteay Meanchey and Oddar Meanchey. Then, the two countries agreed to a ceasefire that went into effect from 29 July 2025 and a peace deal on 26 October 2025. However, sustained cross-border attacks resumed from 7 December, with both sides accusing each other of breaching the deal first.

The December attacks, involving artillery and airstrikes, occurred along multiple border provinces on both sides. The cross-border clashes and strikes have mostly been concentrated in and around disputed temple areas, which are off-limits to the public, including Prasat Ta Muen Thom, Prasat Ta Kwai, Chong Bok, Khao Phra Wihan, Chong An Ma and Chong Chom. Dozens have been killed and hundreds of thousands displaced on both sides of the border.

What to Expect:

The latest cross-border clashes, including airstrikes, may lead to further airspace closures. The Thailand-Cambodia overland border is likely to stay closed until further notice. A new ceasefire could be reached. However, escalation remains possible due to conflicting claims and the breakdown of the peace agreement.
