US President Donald Trump called Thailand and Cambodia on Friday to bolster the peace deal he brokered after fresh clashes erupted between the Southeast Asian neighbours, the White House said.

Trump co-signed a truce between the two countries on October 26 during a tour of Asia, touting it as one of several peace deals around the world that he believes should win him the Nobel Prize.

But Thailand suspended the deal on Monday after a landmine blast, and the two sides traded accusations of new clashes on Wednesday in which Phnom Penh said a civilian was killed.

“President Trump held calls with Thailand and Cambodia in an effort to mediate the most recent conflict,” the White House said in a statement.

“He engaged with Malaysia as well to help end the violence.”
