President Donald Trump has quickly found that there is very little the United States can do to force China to stop North Korea from testing intercontinental ballistic missiles.

However, Trump foreign policy aide Sebastian Gorka told Fox News on Thursday to not count out the president's secret weapon -- his angry tweets.

When asked what influence Trump had left to force China's hand and get it to change North Korea's behavior, Gorka's first instinct was to point to the president's large presence on social media.

"We have, you know, the president's Twitter feed," Gorka said. "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 then made the case that China controls the majority of what gets imported into North Korea and that it hadn't done enough to exert pressure.

However, Gorka was then asked if Trump's rage tweets against China would really be enough to get it to change its long-standing foreign policy positions.

"If you can win a U.S. election with it, I think it's pretty powerful," Gorka said. "Don't you?"
