Thailand and Cambodia are set to hold talks Monday to discuss an end to their deadly border clashes after US President Donald Trump warned Washington wouldn’t make a trade deal with either country while the conflict continued.

Senior officials from both countries said they were still waiting to hear final details on the deals after comments by the U.S. commerce secretary, Howard Lutnick.
