“104 percent tariffs in China are not enough. I’m advocating 400 percent,” he said.

“I do business in China. They don’t play by the rules,” continued O’Leary, who is also the chairman of O’Shares Investment and private-equity firm O’Leary Ventures. “They’ve been in the World Trade Organization for decades. They have never abided by any of the rules they agreed to when they came in for decades. They cheat, they steal, they steal [intellectual property]. I can’t litigate in their courts. They take product technology, they steal it, they manufacture it and sell it back here,” he said.

O'Leary explained this wasn't about tariffs anymore but about how no one has taken on China for decades while they behaved badly — no one, until Trump.

"As someone who actually does business there, I've had enough," O'Leary said, saying he spoke for "millions of Americans." He said finally, with Trump there was an administration who was saying "enough."

O'Leary said we had all the cards and Xi Jinping, the Chinese leader should be on a plane here to work it out because "Xi can only stay the Supreme Leader if people are employed." He didn't hold back, "It's time to squeeze Chinese heads into the wall."

China may end up getting there themselves. The latest from China is that they are going to raise their 34 percent tariffs to 84 percent on Thursday. But at the same time, they were calling for "dialogue" with the U.S.
