So, tariffs are the new “I’m gonna hold my breath till I get what I want” move from the toddler in chief.

President Trump on Monday threatened to immediately impose [additional] tariffs on $300 billion in Chinese goods if Chinese President Xi Jinping does not appear at this month’s Group of 20 (G-20) summit.

Asked during a CNBC interview if the new tariffs would take effect if Xi does not attend the gathering of world leaders in Osaka, Japan, Trump responded, “Yes, it would.” Trump said he would be “surprised” if Xi did not attend because the two leaders are expected to meet to discuss the U.S.-China trade dispute.

“He’s actually an incredible guy. He’s a great man. He’s very strong and very smart, but he’s for China and I’m for the United States,” the president said during a phone interview with the cable business news channel.

Alternativly, this may just be a ploy to claim credit when Xi shows up at the G-20 summit. (edited for typo)
