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.

The ceasefire comes days before the U.S. is expected to announce new trade tariff decisions. Cambodia and Thailand have both been two of the hardest-hit countries as a result of Trump’s trade war, with 36% tariff on goods from both countries taking effect this coming Friday.

The talks between commanders on both sides were seen as a crucial test of whether the cease-fire deal reached on Monday would result in a lasting peace.
