Analysis-Fear of the dark: Taiwan sees wartime frailty in communication links with world

By Sarah Wu and Yimou Lee

TAIPEI (Reuters) -Taiwan is scrambling to secure its communications with the outside world against an attack by China, but even in peacetime cannot quickly repair critical undersea internet cables and lacks suitable satellite backups, experts and officials say.

China, which has never renounced the use of force to bring Taiwan under its control, has ramped up military and political efforts to force the democratically governed island to accept its sovereignty.

The Ukraine war has lent new urgency to Taiwan's efforts to bolster its security, especially against Chinese cyber attacks or attempts to sever any of 14 cables that connect it to the global internet.

"Strategic communications, internally and externally, is what keeps us up at night, particularly in the aftermath of Ukraine," said Tzeng Yisuo, an analyst at Taiwan's top military think tank, the Institute for National Defence and Security Research.

Taiwan has zeroed in on low-Earth orbit satellites as a solution, and has launched a two-year trial programme to boost internet services by leaning on international satellite providers.

Taiwan's total satellite bandwidth is about 0.02% of what its undersea cables provide, according to Kenny Huang, chief executive at Taiwan Network Information Center, the island's internet domain manager.

Huang said Taiwan has struggled to attract interest from international satellite companies because of strict regulations on ownership, which limit foreign shares to a maximum of 49%, and a lack of financial sweeteners.

"There's little incentive for them (foreign companies)," he said. "Regulations must be changed."

Defence experts say that although Taiwan can draw lessons from Ukraine's use of Starlink, a satellite network developed by Elon Musk's U.S.-based space exploration company SpaceX, they worry about relying on a commercial actor with business interests in China.

"Elon Musk, we are not certain if he cares more about China's market," Tzeng said, referring to Tesla's sales in China. "We won't put all our eggs in one basket."

Taiwan does not own any Starlink terminals. SpaceX did not respond to a request for comment.

Taiwan is also strengthening the resilience of wartime communication channels for top commanders, including the president, according to one senior government official and another person familiar with government efforts.

"We are taking notes from Zelenskiy," a senior Taiwan security official said, referring to Ukrainian President Volodymyr Zelenskiy's strong presence on social media.
