PresidentDonald Trump said he’s ready to impose tariffs on an additional $267 billion in Chinese goods on short notice, on top of a proposed $200 billion that his administration is putting the final touches on.

The implementation of tariffs on $200 billion of products from China “will take place very soon depending on what happens,” Trump told reporters on Air Force One on Friday. “I hate to do this, but behind that there is another $267 billion ready to go on short notice if I want.”

If the administration moved ahead, it would more than cover the entire value of goods imports from China, according to U.S. government data from last year. The U.S. imported $505 billion of Chinese products in 2017, Census Bureau figures show. U.S. stocks erased gains after Trump’s remarks.

The Trump administration has already slapped duties on $50 billion of Chinese exports since July, which spurred immediate in-kind retaliation from Beijing.
