State Department officials are in Malaysia to assist in the ceasefire talks between Thailand and Cambodia, Secretary of State Marco Rubio announced.

The two Southeast Asian countries have been involved in a deadly border conflict since late last week, fighting that has resulted in at least 35 deaths and the displacement of more than 218,000 people. Over the weekend, Trump spoke to the leaders of Thailand and Cambodia and announced that ceasefire talks would be held “immediately” after threatening to back out of trade talks with them if the fighting continued.
