Trump agreed to suspend plans to raise tariffs on $200 billion worth of Chinese products from 10 percent to 25 percent in order to pave the way for trade talks with Beijing, but warned that if the negotiations do not succeed within three months, the tariffs will be hiked as planned.

Since then, the two countries have exchanged several rounds of trade duties on hundreds of billions of dollars worth of goods.
