The deadly conflict on the Thai-Cambodian border pits a longtime United States ally with decades of experience against a relatively young armed force with close ties to China.

The deadliest conflict between the two nations in 14 years, now in its third day, extended to provinces about 200 miles south of where clashes first began.

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

Thai and Cambodian soldiers have clashed along the two countries' border in a major escalation of a festering dispute over territory that killed least 14 people, mostly civilians.

The fighting began on Thursday morning close to the ancient Ta Muen Thom temple, beside the border between Thailand’s Surin province and Cambodia’s Oddar Meanchey province.View on euronews
