Thailand and Cambodia agreed Monday to halt five days of fighting along their disputed border that’s killed at least 36 people, after President Donald Trump’s tariff threats accelerated a regional push for a diplomatic solution.

President Trump took a victory lap Monday after Cambodia and Thailand reached a cease-fire deal to stop deadly fighting that erupted between the two Southeast Asian neighbors last week. On Saturday, the president had called up the leaders of the two countries and halted trade negotiations with them in a bid to stop the conflict.
