When a Taiwanese telecoms company detected that an international undersea cable was damaged earlier this month, it worked to divert internet traffic from the broken line to keep customers on the island connected.

The incident raises concern China will try to cut all undersea cables to Taiwan in the event of a military invasion, so Taiwan is racing to develop a satellite-based internet service.

In 2023, the outlying Matsu Islands, within view of the Chinese coast, endured patchy internet for months after two undersea internet cables broke. These fiber optic cables that connect Taiwan to the internet suffered about 30 such breaks between 2017 and 2023.

On Wednesday, China's Taiwan Affairs Office dismissed the accusations, claiming undersea cable damage is part of common maritime accidents. It claimed Taiwan was making baseless accusations against China and exaggerating “so-called grey zone threats.”
