Chinese President Xi Jinping should press Vladimir Putin to "halt the war crimes" in Ukraine, the US has urged.

The two will meet again on Tuesday for official talks during Mr Xi's first visit to Moscow since the invasion.

The White House's National Security Council spokesman called on Mr Xi to urge his Russian counterpart to withdraw troops from Ukraine.

John Kirby said seeking a ceasefire would not be enough.

"We hope that President Xi will press President Putin to cease bombing Ukrainian cities, hospitals and schools, to halt the war crimes and atrocities and to withdraw his troops," he said.

"But we are concerned that instead China will reiterate calls for a ceasefire that leaves Russian forces inside Ukraine's sovereign territory and any ceasefire that does not address the removal of Russian forces from Ukraine would effectively ratify Russia's illegal conquests."

Yeah he will certainly do as he is told. ????
