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.

Thailand said Tuesday that Cambodia violated their hours-old cease-fire that ended days of fighting between the neighbors over their disputed border.

The leaders of Cambodia and Thailand agreed to a ceasefire in a bid to bring an end to their deadliest conflict in more than a decade.
