Photos of Trump in China for talks with Xi Jinping

China’s Xi Jinping has warned President Donald Trump that their two countries could clash over Taiwan if the issue is not handled properly. That was an unusually harsh admonition that stood in contrast to the American leader’s praise for his counterpart. The exchange Thursday at a highly anticipated summit in Beijing underscored just how far apart Trump and Xi remain on thorny issues, including the war in Iran, trade disputes and Washington’s relations with Taiwan. Taiwan is a self-ruled island that China claims as part of its territory. The exchange also suggested that Trump’s three-day visit to China is likely to be longer on pageantry and symbolism than substantive political or economic breakthroughs.
