Thailand and Cambodia reached an “immediate and unconditional” ceasefire deal Monday, bringing an end to days of heavy fire stemming from long-standing border disputes after President Donald Trump got involved in the conflict over the weekend.

"The U.S. already flunked the test and that should be a wakeup call," a former senior U.S. State Department official told Newsweek.

While the US and China urge a ceasefire, Thailand’s acting prime minister says he’s wary of Cambodia’s ‘acting in good faith’.

The leaders of Cambodia and Thailand have agreed to meet to negotiate a ceasefire, according to a social media post by United States President Donald Trump on Saturday.
