BEIJING — Chinese and American officials meeting in Beijing agreed to set up a mechanism to work through an escalating dispute over trade at the end of talks Friday, Chinese state media said. But it said “big differences” remain on some matters.

The Commerce Ministry said the two sides discussed expanding U.S. exports to China, trade in services, the protection of intellectual property rights and how to resolve the use of tariffs and non-tariff measures, according to the official Xinhua News Agency.

The two sides “reached consensus in some areas,” Xinhua said. It did not provide specifics.

There was no immediate comment from the U.S. delegation.
