Sebastian Gorka, a deputy assistant to President Trump, said Thursday that Trump would be able to pressure China to do more to stymie North Korea's aggression through his Twitter feed.

"We have the president's Twitter feed. We have the most powerful man in the world making it very clear that we came out of the Mar-a-Lago summit with very high hopes," Gorka told Fox News when asked what the Trump administration could do to get China to act. "Let's look at the facts. Forget op-ed pieces in newspapers across the globe. China controls more than 80 percent of the imports into North Korea. That is a massive point of leverage. China has wanted a buffer state since 1950. We understand it. But at some point, a buffer state that destabilizes the region isn't good for Beijing either.

"So the president has made it clear he is not satisfied. He is disappointed with what Beijing has done since Mar-a-Lago, and he wishes to see them step up to the plate."

When pressed about whether the president's Twitter feed can persuade Beijing, Gorka doubled down.

"If you can win a U.S. election with it, I think it's pretty powerful," he said.

Trump had hoped that China would do more to curb North Korea's missile and nuclear weapons programs, but the president has been dissatisfied with China since then.

"I am very disappointed in China," he said Saturday on Twitter. "Our foolish past leaders have allowed them to make hundreds of billions of dollars a year in trade, yet they do NOTHING for us with North Korea, just talk."

North Korea has test-launched two intercontinental ballistic missiles in the past month. Experts said the most recent intercontinental ballistic missile launched, which occurred Friday, was capable of reaching the continental U.S.
