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.

Commerce Secretary Howard Lutnick said Wednesday that Thailand and Cambodia reached trade agreements with the U.S. just days after the Southeast Asian countries agreed to a ceasefire to end five days of deadly clashes along their border.

Cambodia will scrap tariffs on US goods and pledged to buy as many as 20 Boeing Co. 737 Max jets in a bid to narrow its trade gap with Washington, according to Deputy Prime Minister Sun Chanthol.
