Chinese research ships have increased their activity around Taiwan's undersea communications cables, as reported by a Sky News investigation. This is part of China's 'gray zone' campaign aimed at mapping seabeds and monitoring critical infrastructure without triggering open conflict. The undersea cables are vital for Taiwan's economy and international connections, making them strategically vulnerable. The U.S.-China Economic and Security Review Commission (USCC) has released a report highlighting the potential for gray zone sabotage of these cables, emphasizing their importance to national security. The report introduces a new vulnerability index to assess risks to these networks. Taiwan's Ministry of National Defense has noted a rise in Chinese naval and coast guard activity, further increasing pressure on the island. Analysts warn that this growing presence could lead to significant disruptions in communications.
