Thai and Cambodian leaders are set for talks Monday to halt the deadliest clash between the neighbors in more than a decade, with the US and China sending envoys after President Donald Trump used tariff threats to press for a ceasefire.

Both countries' foreign ministers agreed that no other country should be involved in the issue, Mohamad Hasan said.

Tensions have bubbled between the two neighbors for months, flaring on Thursday as Cambodia and Thailand exchanged fire.

The FCDO travel advice for Thailand says the same about the border crossing, but adds: “Take extra care and stay alert in border areas and follow the instructions of local authorities, especially at tourist destinations such as the Preah Vihear temple, the Ta Kwai temple and the Ta Muen Thom temple.
