Philippines and Taiwan Explore Cooperation to Protect Undersea Cables
The Philippines and Taiwan are considering deeper cooperation to protect critical undersea communication cables and address gray-zone activities at sea.

The Philippines and Taiwan are considering deepening cooperation to protect undersea communication cables and address gray-zone activities at sea. The initiative comes amid rising maritime tensions between the two sides and China.
Undersea cables are considered critical infrastructure because they carry a large proportion of global data communications. The two sides aim to ensure the security of cable routes, particularly around the Bashi Channel, which lies between Taiwan and the Philippines.
The planned cooperation is expected to cover areas such as information sharing and technical capacity building. Strengthening maritime surveillance and preventing interference with cable routes could also be addressed in the future. However, no concrete decision has yet been announced regarding joint patrols or holding vessels accountable.
Following incidents involving damage to undersea cables, Taiwan has stepped up efforts to protect its communications infrastructure and plans to make greater use of unmanned systems for maritime surveillance.
This month, the Philippines also deployed a large coast guard vessel and an aircraft to monitor a Chinese research vessel operating off the coast of Batanes province in the north of the country. The area is strategically important due to its proximity to undersea cable routes.
Meanwhile, China has warned the Philippines to adhere to its one-China policy. The developments highlight that protecting undersea cables is not merely a technical infrastructure issue but is also important for regional maritime security.
