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

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.

President Trump said on Saturday that both countries had agreed to a halt in the fighting. But on Sunday morning, skirmishes erupted once more.
