U.S. Treasury Secretary Steven Mnuchin said on Saturday he may travel to China, a move that could ease tensions between the world's two largest economies, as international policymakers acknowledged Beijing needs to change its trade practices.

The United States has threatened to impose tariffs on up to $150 billion of Chinese imports to try to force changes in Beijing's industrial policies, which Washington says are aimed at acquiring American intellectual property.

Mnuchin told reporters he was continuing to have discussions with his Chinese counterparts to try to resolve the differences over trade, but said he may go to Beijing.
