Treasury Secretary Steven Mnuchin reportedly urged China to come back to trade talks, threatening more tariffs if Beijing doesn’t live up to its commitments.

“If they want to come back to the table and complete the deal on the terms that we were continuing to negotiate, that would be great,” he said Saturday in Fukuoka, Japan, according to the New York Times. “If not, as the president said, we’ll move on with tariffs.”

The comments came on the first day of the annual G-20 meeting of finance ministers from the world’s biggest economies.

The latest round of China-US talks, last month, ended without a breakthrough. The next day, the Trump administration raised tariffs on billions of dollars of Chinese goods to 25 percent.
