Thailand and Cambodia have signaled their readiness to negotiate a ceasefire after mediation by U.S. President Donald Trump.

Thai and Cambodian leaders agreed to halt hostilities in their deadliest border conflict in more than a decade, after a push by the US and regional powers for a diplomatic resolution.

Thailand’s Foreign Ministry confirmed Trump’s call with acting Prime Minister Phumtham Wechayachai. “However, Thailand would like to see sincere intention from the Cambodian side,” it said. The ministry reiterated its call for bilateral talks between the two sides.
