POTOMAC FALLS, Va. — President Trump says the United States is prepared to act alone if China does not take a tougher stand against North Korea’s nuclear program.

Trump’s comments in an interview with the Financial Times come just days before he is due to host Chinese President Xi Jinping at his Mar-a-Lago estate in South Florida. The two are expected to discuss issues including North Korea, trade and territorial disputes in the South China Sea during their meeting Thursday and Friday.

“Yes, we will talk about North Korea,” Trump told the newspaper for a story that appeared on its website Sunday. “And China has great influence over North Korea. And China will either decide to help us with North Korea, or they won’t. And if they do that will be very good for China, and if they don’t it won’t be good for anyone.”

Trump said trade was the incentive for China to work with the United States. Still, he said the United States could “totally” handle the situation in North Korea without China’s help.

Asked how he would tackle North Korea, Trump said: “I’m not going to tell you. You know, I am not the United States of the past where we tell you where we are going to hit in the Middle East.”

While China provides diplomatic and economic support to its neighbor, it claims that its influence over Kim Jong Un’s government is limited.

The relationship between the United States and China has been uncertain since Trump’s election. During his campaign, he accused China of unfair trade practices and threatened to raise import taxes on Chinese goods and declare Beijing a currency manipulator, though it is unclear whether Trump will follow through with either threat.

Trump told the newspaper that he doesn’t “want to talk about tariffs yet, perhaps the next time we meet.”

Trump’s ambassador to the United Nations Nikki Haley, also offered tough talk on China, telling ABC’s “This Week” that the U.S. is pressing China to take a firmer stand on North Korea.
