Trump gets through to both sides by citing the advantages of coming to terms rather than risking important trade deals with Washington.

Thailand’s Foreign Ministry confirmed Trump’s call with acting Prime Minister Phumtham Wechayachai. “However, Thailand would like to see sincere intention from the Cambodian side,” it said. The ministry reiterated its call for bilateral talks between the two sides.

President Trump said he had intervened to help stop the deadly strife, now in its third day, after it extended to provinces about 200 miles south of where clashes began.
