A major speech on China by Vice President Mike Pence that was expected to take a tough line on Beijing has been rescheduled for later this year, a White House official said.

The tone of the speech, originally scheduled for delivery in June, will be dictated by the needs of the moment, the person said late on Thursday, adding that it would be given at the Wilson Center think tank in Washington, as initially planned.

The news comes after Beijing announced that top officials would head to Washington in early October to hold talks aimed at ending a tit-for-tat trade war, now in its second year, which has roiled markets and hammered global growth.
