China has suspended fuel exports a week after President Donald Trump pressed the Communist nation’s leader to help stabilize global supply.

The country’s refiners have suspended fuel exports for October, four people briefed on the matter told Reuters on Thursday.

On Wednesday, state-owned PetroChina canceled a handful of gasoline and jet fuel shipments planned for October, most of which it had agreed to within the past two weeks, three of the sources said.

During Chinese President Xi Jinping’s state visit, Trump urged him to “increase production of refined petroleum products to stabilize global supply,” according to a Sept. 25 White House fact sheet.
