Without providing details, President Donald Trump said he has a plan to unilaterally stop North Korea’s nuclear program during a wide-ranging Q&A published Sunday by The Financial Times.

Trump said the issue of North Korea would be discussed when he meets Chinese leader Xi Jinping in Florida later this week. “China has great influence over North Korea,” Trump said. “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.
