Internet connectivity is a lifeline — albeit a fragile one — for Taiwan. A recent war game staged in Taipei with experts from the military, tech industries, academia and government suggested that, in the event of a Chinese blockade, the island would be particularly vulnerable to a communications cutoff.
The threat to Taiwan’s digital infrastructure was made plain in February, when Chinese maritime vessels severed two submarine cables connecting the Taiwan to Matsu, a tiny archipelago that belongs to Taiwan but is located just off China’s coast. The months-long outage deprived residents of Internet access and left Matsu, which houses a strategic military base, open to attacks. The damaged cables also exposed the vulnerability of the US tech giant Google, which has a data center on Taiwan’s western coast.
Currently, 15 submarine cables connect Taiwan to global telecommunications. A Chinese invasion or prolonged blockade could thus cut off the island from the world, with consequences for the global economy and financial markets. Such an outcome could also threaten the security of the US and its regional allies, including Japan. As a result, the Taiwanese government must focus on strengthening communication capabilities and ensuring robust and reliable Internet connectivity.
One potential solution is to engage the services of Starlink, the mobile satellite Internet system operated by Elon Musk’s rocket company, SpaceX. Some would argue that Musk, who also owns X (formerly Twitter), is the Internet’s most powerful man; others would describe him as the most erratic. Starlink, a key part of Musk’s business empire, provides Internet connectivity globally through its more than 4,500 low Earth orbit satellites.
Soon after Russia invaded Ukraine, Musk allowed his satellites to broadcast in Ukraine free of charge and donated thousands of Starlink terminals to the government in Kyiv, helping it circumvent Russia’s attack on Ukraine’s telecoms infrastructure. Since then, Starlink has become an essential tool of the Ukrainian military, allowing it to gather intelligence on Russia’s latest troop movements and to communicate securely with NATO partners.
Yet while Musk was touted as a hero early in the war, government leaders are increasingly beholden to his whims. Last year, Musk disabled Starlink near the coast of Crimea to thwart a Ukrainian drone attack on Russian ships, arguing in a text to then-Ukrainian deputy prime minister Mykhailo Fedorov that the country was “going too far and inviting strategic defeat.”
Using Musk’s Starlink to access the Internet and connect with the outside world could prove problematic for Taiwan.
First, relying solely on Starlink means that any systematic failure or data compromise could be irreversible.
Second, Musk has explicitly identified himself as “pro-China” and even suggested that Taiwan should become a “special administrative zone” of the People’s Republicof China, similar to Hong Kong.
Third, Musk has substantial business interests in China: Tesla, Musk’s electric vehicle (EV) company, has its most productive manufacturing hub in the country, which is also the world’s largest EV market.
Given all this, in the event of a military conflict between China and Taiwan, there is no guarantee that Musk would not accede to China’s demands. Without sovereign control of its data, including data flows and data storage, Taiwan’s national security would be at risk.
To protect itself, Taiwan — already a global leader in the semiconductor supply chain — must develop indigenous capabilities in satellite communications and technologies. By integrating and consolidating resources, the Taiwanese government could establish, and maintain control over, public-private partnerships that would be able to rapidly ramp up capacity in the event of a war. The government should also streamline the procurement process to make it easier for start-ups to work with defense contractors.
While Taiwan’s National Development Fund invests in satellite technologies and critical communications infrastructure, the Ministry of Defense and the Ministry of Digital Affairs should work with the Taiwan Space Agency to exchange intelligence and establish a defense-shield system with partners such as Japan, South Korea, the Philippines and Australia. Taiwan needs to launch 120 satellites to ensure uninterrupted backup coverage, but policymakers are racing against time and must leverage allies’ support.
For its part, the US government should consider allocating some of the funds provided by the CHIPS Act and the National Defense Authorization Act to co-develop satellite-communication technology and the relevant semiconductor chips with Taiwan. Moreover, as part of its Indo-Pacific strategy, the US should take the lead in establishing this alliance, by forming working groups, establishing technology standards and arranging high-level exchanges.
The situation in Taiwan is not entirely analogous to that in Ukraine. Unlike Ukraine, which shares a long land border with Russia, Taiwan is separated from China by the notoriously rough seas of the Taiwan Strait. Moreover, Taiwan imports more than 90 percent of its energy, which means that a blockade would swiftly bring the island’s economy to a halt, in addition to threatening the security of its neighbors and the Indo-Pacific region more generally.
A disruption of Taiwan’s Internet connectivity could all too easily turn into a global crisis. As tensions across the Taiwan Strait rise, the island’s security is becoming a shared geopolitical concern. Defeating China might not be possible, but outsmarting it certainly is. Taiwan and its allies should start investing today to ensure that the island’s links to the outside world remain robust, even at the darkest hour.

The Chinese Communist Party (CCP) has long been expansionist and contemptuous of international law. Under Chinese President Xi Jinping (習近平), the CCP regime has become more despotic, coercive and punitive. As part of its strategy to annex Taiwan, Beijing has sought to erase the island democracy’s international identity by bribing countries to sever diplomatic ties with Taipei. One by one, China has peeled away Taiwan’s remaining diplomatic partners, leaving just 12 countries (mostly small developing states) and the Vatican recognizing Taiwan as a sovereign nation. Taiwan’s formal international space has shrunk dramatically. Yet even as Beijing has scored diplomatic successes, its overreach
In her article in Foreign Affairs, “A Perfect Storm for Taiwan in 2026?,” Yun Sun (孫韻), director of the China program at the Stimson Center in Washington, said that the US has grown indifferent to Taiwan, contending that, since it has long been the fear of US intervention — and the Chinese People’s Liberation Army’s (PLA) inability to prevail against US forces — that has deterred China from using force against Taiwan, this perceived indifference from the US could lead China to conclude that a window of opportunity for a Taiwan invasion has opened this year. Most notably, she observes that
For Taiwan, the ongoing US and Israeli strikes on Iranian targets are a warning signal: When a major power stretches the boundaries of self-defense, smaller states feel the tremors first. Taiwan’s security rests on two pillars: US deterrence and the credibility of international law. The first deters coercion from China. The second legitimizes Taiwan’s place in the international community. One is material. The other is moral. Both are indispensable. Under the UN Charter, force is lawful only in response to an armed attack or with UN Security Council authorization. Even pre-emptive self-defense — long debated — requires a demonstrably imminent
Since being re-elected, US President Donald Trump has consistently taken concrete action to counter China and to safeguard the interests of the US and other democratic nations. The attacks on Iran, the earlier capture of deposed of Venezuelan president Nicolas Maduro and efforts to remove Chinese influence from the Panama Canal all demonstrate that, as tensions with Beijing intensify, Washington has adopted a hardline stance aimed at weakening its power. Iran and Venezuela are important allies and major oil suppliers of China, and the US has effectively decapitated both. The US has continuously strengthened its military presence in the Philippines.
