U.S. President Donald Trump said on Thursday he expects there to be substantive negotiations between the United States and China on trade this weekend and predicted that punitive U.S. tariffs on Beijing of 145% would likely come down.

Trump said the deal increases access for U.S. agricultural products, though he added that the final details were still being written up. Britain says the deal will cut tariffs on U.K. cars from 27.5% to 10% and eliminate tariffs on steel and aluminum.

Beijing says it will meet with American officials to discuss trade, but warned Washington against using the engagement to ratchet up pressure on China.
