President Trump warned the U.S. would "solve" North Korea's nuclear threat by itself if China did not contribute.
In an interview with the Financial Times published Sunday, Trump said North Korea would be one of the topics he would discuss with Chinese President Xi Jinping when he arrives at his Florida resort this coming week.
"If China is not going to solve North Korea, we will," Trump said. "That is all I am telling you."
Trump acknowledged that China has "great influence" over North Korea, but the U.S. could "totally" handle it alone.
"China will either decide to help us with North Korea, or they won't," he said. "If they do, that will be good very good for China. And if they don't, it won't be good for anyone."
North Korea has ramped up missile tests since Trump's inauguration. While not all of the tests have been successful, it has been enough to prompt Secretary of State Rex Tillerson to hint at possible military action.
WATCH | In February, Trump condemned a missile test that occurred during a visit with Japanese Prime Minister Shinzo Abe.
There is a real possibility that North Korea will be able to hit the U.S. with a nuclear-armed missile by the end of the first Trump term.
The National Security Council has completed a review of options on North Korea Trump ordered after his inauguration, the Times reports.
I have great respect for [Xi Jinping]. I have great respect for China.
Trump also spoke on Brexit, saying he thought it would be "great" for the United Kingdom and "really good for the European Union." He said he did not expect other nations to follow suit.
He also expressed optimism about his upcoming meeting with Xi, despite previously saying that China was "raping our country."
