First came a push from the Malaysian premier, then China reached out, but it was only after President Donald Trump called Thailand's leader last week that Bangkok agreed to talks with Cambodia to end an escalating military conflict.

The talks, announced by a spokesperson for the Thai prime minister's office on Sunday, come after pressure from U.S. President Trump to reach a ceasefire.

Fresh cross-border clashes between Thailand and Cambodia broke out on Sunday hours after US President Donald Trump announced the two Southeast Asian nations had agreed to ceasefire talks.
