U.S. President Donald Trump is positioning a personal discussion with his Chinese counterpart as the key to preventing the world¡¯s largest economies from spiraling deeper into their trade and technology fight.

But Chinese leader Xi Jinping is making clear that a phone call doesn¡¯t come without a price ¡ª a resolute stand so far that¡¯s apparently keeping Trump up late into the night.

¡°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 posted on Truth Social at around 2:17 a.m. His complaint came after a flurry of U.S. officials said this week the two men were set to speak.
