Rubio reiterated President Donald Trump’s desire for peace in a call with Cambodian Prime Minister Hun Manet, according to a statement from the US on Thursday.

“Secretary Rubio further reaffirmed that the United States is prepared to facilitate discussions to ensure peace and stability between Cambodia and Thailand,” State department spokesperson Tommy Pigott said in the statement.

Thailand and Cambodia are talking for the first time since clashes began on Dec 7, with at least 44 people killed and more than half a million civilians displaced on both sides of the border.

Five days of clashes in July ended with an initial ceasefire agreement mediated by Malaysia and the US.
