Donald Trump's second term as US president is expected to bring continued uncertainty and potential disruption to international relations. His confrontational stance towards China and focus on asserting American interests may lead to significant shifts on the global stage. While his policies could harm China's economic growth and intensify strategic considerations, his personal rapport with Chinese President Xi Jinping leaves allies and adversaries uncertain about his commitment to confronting China militarily. Trump's approach to the Russia-Ukraine conflict is unclear, raising concerns about potential concessions and undermining of European security. In the Middle East, his transactional diplomacy and support for Israel are expected to continue, while his aggressive stance on Iran and pragmatic relationships with Gulf states may contribute to heightened tensions. In the Indo-Pacific, Trump's policies are likely to intensify the rivalry between the US and China, but his transactional approach to alliances could undermine long-term strategic cohesion. Overall, Trump's second term is expected to challenge the post-World War II international order and generate uncertainty in global geopolitics.
