President Donald Trump said in a late-night social media post that Chinese leader Xi Jinping was very tough to make a deal with, raising questions about whether a fragile economic truce between the world’s two largest economies will hold.

U.S. President Donald Trump said Wednesday that China's president, Xi Jinping, was "extremely hard" to make a deal with. A senior White House official told CNBC earlier on Monday that Trump and Xi are likely to speak this week.

"I like President Xi of China, always have, and always will, but he is VERY TOUGH, AND EXTREMELY HARD TO MAKE A DEAL WITH," Trump said in a post on Truth Social.
