At a meeting in the last week, some senior advisers to the president indicated they weren’t sure what Trump would need to think he got a good trade deal, according to two people familiar with the matter. And another goal of the trip is for the U.S. to show China some respect for its help in pressuring North Korea to abandon its nuclear weapons program.

Mnuchin said the administration is “very concerned about forced transfers of technology” and “forced joint ventures” for U.S. companies seeking to do business in China. “These are all the issues we will be discussing,” he said at the Milken conference.

Chinese officials are open to discussing issues including technology transfers, widening access to China’s markets, increasing U.S. imports and Chinese industrial policy, said He Weiwen, deputy director of the Center for China and Globalization in Beijing and a former Commerce Ministry official. They won’t bargain on narrowing Trump’s proposed tariffs or reducing the tariff rates, he said — China has demanded the tariffs be withdrawn altogether.
