China’s quest for secure transit routes faces persistent challenges across the globe. Key corridors, whether the Suez Canal, CPEC, or the Arctic, are complicated by territorial disputes, geopolitical rivalries, and strategic chokepoints. Some obstacles arise from the interests of other powers, such as the U.S. and its allies, while others are dictated by geography or international law. These vulnerabilities highlight China’s dependence on stable and open trade routes. While not every challenge is a deliberate blockade, the cumulative effect constrains China’s global ambitions.
