Thailand and Cambodia have signaled their readiness to negotiate a ceasefire after mediation by U.S. President Donald Trump.

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.

Bangkok and Phnom Penh have been fighting over territory disputed since colonial power France drew the border between them more than a century ago.
