The working groups of China and the US will maintain frequent communication before the next round of high-level talks in the US in September, Ministry of Commerce spokesman Gao Feng said at a news conference in Beijing on Thursday.

Gao said both sides clarified the principles and approach for future negotiations. They discussed China's possible purchase of more US agricultural products based on domestic need, and the US creation of favorable conditions for the transaction, he added.

Some Chinese companies have purchased US agricultural products and applied for the removal of additional tariffs on these foodstuffs, Gao said.

Asked whether Huawei Technologies Co was mentioned in the latest talks, Gao said it is hoped that the US will implement its commitment on Huawei as soon as possible.

Wang Xiaosong, a professor of international trade at Renmin University of China's School of Economics, said the talks need to be conducted in the spirit of equality and mutual respect, while placing extreme pressure on the other party can only hinder progress toward a deal. The professor said the two nations need to align their interests and find a middle ground.
