A ceasefire between Thailand and Cambodia appeared to largely be holding on Tuesday as military commanders from both countries met for negotiations, even as the Thai army accused Cambodian troops of violating the truce overnight.

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.
