The document discusses the shift in U.S. international business policies under the Trump administration, which has withdrawn from treaties like the Trans-Pacific Partnership and renegotiated others, imposing tariffs that affect foreign corporations. This protectionism is partly driven by concerns over job losses in the U.S. due to cheaper labor markets abroad, particularly in Southeast Asia, and has paved the way for rivals like China to negotiate advantageous trade deals. The long-term implications suggest a potential decline in U.S. trade volumes and a challenge to its status as a global leader in free trade.
