Commerce Secretary Wilbur Ross visited Beijing for trade negotiations over the weekend, and those talks produced "positive and concrete" results, said a statement from the Chinese government in state-run media Sunday. However, if the Trump administration proceeds with its proposal to impose 25 percent tariffs on $50 billion of Chinese tech products, the statement warned, "all the economic and trade benefits negotiated by both sides are not going to take effect." Further economic negotiations should be aimed toward mutual benefit and "not waging a trade war," the statement said.
