China could suffer significant economic consequences if it were to blockade or invade Taiwan, a report from a Washington think tank reveals. The report, titled Troubled Straits: Analyzing Trade Chokepoints in the South China Sea by the Center for Strategic and International Studies, emphasizes that any military action by China disrupting the Taiwan Strait may severely impact its economy more than a disruption in the Malacca Strait. The Taiwan Strait serves as a crucial route for China’s economic sustenance, with about $1.3 trillion of Chinese trade passing through it, significantly more than the Malacca Strait.
The report underscores the Taiwan Strait’s importance not only for Taiwan but also for China’s economic well-being. It serves as a vital channel for China’s industrial imports, including essential resources like oil, coal, natural gas, ores, and metals from resource-rich nations. In 2024, a substantial portion of China’s total imports, especially maritime imports, traversed the Taiwan Strait, highlighting its critical role in China’s trade network.
Moreover, the Taiwan Strait plays a pivotal role in China’s domestic shipping operations, particularly in transporting goods from southern technological hubs like Shenzhen and Guangzhou to major eastern and northern cities. The report points out that any disruption in the Taiwan Strait could force China to resort to land transportation, significantly increasing costs. For instance, moving goods from Guangzhou to Tianjin by land could be three times more expensive than by sea, potentially leading to logistical bottlenecks and economic repercussions across China.
The report also stresses the strategic significance of the Luzon, Malacca, and Taiwan straits for key US allies in Asia. While only a small percentage of US trade passes through these straits annually, they are crucial for countries like Japan, South Korea, and the Philippines. In 2024, these countries collectively shipped goods worth $755 billion through the Taiwan Strait, with Japan heavily reliant on the route for its trade, especially in key technologies like semiconductors. Japanese and Philippine leaders have expressed concerns that any Chinese military action in the Taiwan Strait could draw their nations into the conflict.
