"The U.S. unilaterally exerting pressure on China will get the opposite of what it wants", he said. It wants China to stop stealing USA corporate secrets, abandon plans to boost its high-tech industries at America's expense and stop subsidizing Chinese companies with cheap loans that enable them to compete unfairly. The trade gap narrowed in April and May as farmers front-loaded soybean exports to China before Beijing's retaliatory tariffs came into effect in early July.
The administration has said the tariffs would remain in effect until China opens its markets to more competition and stops what the US says are unfair practices.
China is willing to resolve differences with the United States on an equal footing, the Chinese Government's top diplomat said after meeting US Secretary of State Mike Pompeo, but added they did not address their trade war too specifically.
