President Donald Trump has invited Latin American leaders to take part in a summit in Florida next month, gathering the officials at a moment when the administration is spotlighting what it sees as concerning Chinese influence in the region. Plans for the March 7 summit were confirmed on Thursday by a White House official who was not authorized to comment publicly about the yet-to-be formally announced gathering. It will also come just weeks before Trump is expected to travel to Beijing for talks with Chinese President Xi Jinping. The Trump administration has made it a priority to assert dominance over the Western Hemisphere, where China has long built influence through massive loans and expansive trade.
