World leaders prepare for summits as Xi Jinping seeks to strengthen China's global role

World leaders are preparing for two major summits in South America amid concerns about Donald Trump's return to the White House. His "America First" agenda raises uncertainties for global relations, particularly between the U.S. and China. Chinese leader Xi Jinping sees an opportunity to strengthen China's position as a stable global leader. He aims to improve relations with other countries while navigating potential tensions with the U.S. under Trump, who has proposed significant tariffs on Chinese imports. As Xi attends the APEC and G20 summits, he will promote China as a reliable partner. However, trust-building with U.S. allies may be challenging due to China's recent aggressive actions in the South China Sea and support for Russia.
