How China Will Squeeze, Not Seize, Taiwan

A Slow Strangulation Could Be Just as Bad as a War

Testifying before the Senate Armed Services Committee in 2021, Admiral Philip Davidson, the retiring commander of U.S. military joint forces in the Indo-Pacific, expressed concern that China was accelerating its timeline to unify with Taiwan by amphibious invasion. “I think the threat is manifest during this decade, in fact in the next six years,” he warned. This assessment that the United States is up against an urgent deadline to head off a Chinese attack on Taiwan—dubbed the “Davidson Window”—has since become a driving force in U.S. defense strategy and policy in Asia.

Indeed, the Defense Department has defined a potential Chinese invasion of Taiwan as the “pacing scenario” around which U.S. military capabilities are benchmarked, major investments are made, and joint forces are trained and deployed. Taipei has been somewhat less fixated on this particular threat. But over the last decade, as the cross-strait military balance has tilted in Beijing’s favor, Taiwan’s leaders have ramped up their military spending and training expressly to deter and deny such an attack.

The threat of an amphibious invasion, however, is the wrong focal point for the United States’ efforts to protect Taiwan. China’s patient, long-term Taiwan policy, which treats unification as a “historical inevitability,” together with its modest record of military action abroad, suggests that Beijing’s more probable plan is to gradually intensify the policy it is already pursuing: a creeping encroachment into Taiwan’s airspace, maritime space, and information space. The world should expect to see more of what have come to be known as “gray-zone operations”—coercive activities in the military and economic domains that fall short of war.

This ongoing gray-zone influence campaign will not itself force Taiwan’s formal unification with the mainland. But over the course of many years, the expansion of China’s military, paramilitary, and civilian operations into Taiwan-controlled spaces could reach certain intermediate objectives—most important, preventing the island from achieving formal independence—while preserving Beijing’s options to use force down the road. Left unchallenged, Beijing’s gray-zone campaign could also demonstrate the limits of the United States’ power in Asia. The United States and its allies are unlikely, for instance, to use the advanced missile systems they have built up in the region if China never provides a clear casus belli in the form of a brazen invasion. Instead, U.S. leaders may find themselves mired in debates over whether China has crossed a redline. With Washington hamstrung by uncertainty over how far China intends to push its gray-zone tactics, much of the responsibility for countering China’s campaign of encroachment will fall to Taiwan.

Although Taiwan’s leaders frequently draw attention to China’s coercive activities in and around the Taiwan Strait, most of the major military investments they have made in recent years—including fighter aircraft, tanks, and an indigenously produced submarine—are not well aligned with the insidious nature of the gray-zone threat. Going forward, Taipei should concentrate its efforts on building buffer zones across all domains, hardening its communications infrastructure, and accelerating its foreign direct investment to build economic links that are more resilient against Chinese disruption.

The United States must also break its fixation on the prospect of an invasion and become more alert to the dangers posed by a slow strangulation of Taiwan. Washington should bolster Taipei’s efforts by augmenting Taiwan’s surveillance capabilities, expanding the role of the U.S. Coast Guard across the South China and East China Seas and around Taiwan’s maritime approaches, and coordinating with commercial actors who may feel pressure to comply with Beijing’s restrictions. If current trends persist, it is likely that the Davidson Window will come and go with no war—but with Taiwan’s autonomy and the United States’ credibility both greatly diminished.

DARKENING CLOUDS

Over the past decade, China has asserted itself with increasing potency in East Asia’s airspace, waters, and information sphere. Its coast guard and other maritime law enforcement vessels have used nonlethal methods to gain varied levels of control over waters disputed by Indonesia, Japan, Malaysia, the Philippines, South Korea, and Vietnam. In the early months of 2024 alone, Chinese coast guard vessels have undertaken dangerous maneuvers and fired water cannons to prevent the Philippines from resupplying a military outpost, Chinese diplomats have ignored the international Law of the Sea with new claims in the Gulf of Tonkin, and Chinese vessels have warned off Japanese aircraft operating in Japan’s territorial airspace around the Diaoyu Islands (known in Japan as the Senkaku Islands).

These measures reflect a fundamental intent to impose Chinese domestic law over disputed territories. Although Hong Kong is more directly under Chinese control than are the contested waters in the South China and East China Seas, Beijing’s steady suffocation of the city’s autonomy resembles its strategy toward claimed maritime spaces. China has implemented legal actions that expand its effective control over critical aspects of Hong Kong’s governance, all without resorting to military force.

Taiwan has increasingly become the target of coercive activities that resemble China’s gray-zone repertoire in the South China and East China Seas. The Chinese air force has conducted nearly three times as many incursions into Taiwan’s Air Defense Identification Zone (the area in which aircraft are required to identify themselves to Taiwanese authorities) since January 2022 as it did between 2018 and 2021, according to reports released daily by Taiwan’s Ministry of National Defense. Beijing has also routinely sent ships and aircraft across the median line running through the Taiwan Strait, effacing a de facto boundary that was defined in 1955. The Chinese military has increased the frequency, intensity, and duration of live-fire drills that temporarily establish sea and air control in the waters and airspace surrounding Taiwan, effectively encircling the island. China’s formidable capabilities in information warfare also figure prominently into its gray-zone concept of operations. Beijing saturates Taiwanese media with disinformation and is suspected of cutting submarine Internet cables to outlying islands under Taiwan’s control.

Since 2022, Beijing has pursued less risky measures to slowly squeeze Taiwan.

China’s gray-zone activities in the Taiwan Strait should not be viewed as a mere prelude to an amphibious invasion. Rather, Beijing’s persistent use of similar tactics in nearby waters suggests such actions are the primary methods in a patient, long-term strategy aimed at subjugating Taiwan without resorting to an invasion. With this approach, China is attempting to choke off the island’s control of surrounding waters and airspace and limit its ability to make autonomous military, diplomatic, and economic decisions. Actions along these lines would fall well short of the outright occupation that a successful amphibious invasion might offer. Yet this more ambiguous campaign may yield similar outcomes, leaving Beijing in control of Taiwan in most ways that matter without the necessity of any formal capitulation.

Russia’s failure to rapidly seize Kyiv after its 2022 invasion of Ukraine vividly reinforces the appeal of this strategy. Since 2022, Beijing has shown increased interest in cheaper and less risky measures to slowly squeeze the island, likely a reflection of its recognition, following Moscow’s military struggles, that a swift military victory over Taiwan will be difficult to achieve. China could keep tightening the noose by rolling out more special coast guard patrols that cover ever-greater swaths of the Taiwan Strait or by imposing customs or quarantine measures to curtail commercial flows. These possible operations would not stray far from activities Beijing has already undertaken around Kinmen Island, for example. Such actions do not amount to a blockade in operational or legal terms, but they achieve similar objectives and preserve the option to conduct a more comprehensive and lethal campaign in the future.

LOW RISK, MORE REWARD

Because Davidson was the most senior U.S. military officer in the Indo-Pacific and thanks to rising concern across the U.S. national security community about the pace of China’s military modernization, the Davidson Window was quickly accepted as dogma by U.S. policymakers and military leaders. But a number of factors make an outright Chinese military invasion less likely than a low-intensity encroachment campaign, both before 2027 and well into the future. The Chinese Communist Party has linked unification with Taiwan to the wider goal of “national rejuvenation” by 2049, but Chinese leader Xi Jinping himself has remained vague about what such unification means in practice. China can afford to push its timeline well beyond the Davidson Window without departing from its long-term policy toward Taiwan.

China is also limited by a lack of recent combat experience and low confidence in its capability to conduct joint operations. As long as Beijing’s coercive measures are expanding its effective control over Taiwan, China is likely to keep traveling down this well-worn path—one that can give it much of what it desires at a tiny fraction of the cost of an amphibious invasion. The tepid response to China’s coercion strategy thus far from the United States and its allies has done little to discourage leaders in Beijing. Building and militarizing outposts on the disputed Spratly Islands in the South China Sea, evicting the Philippines from Scarborough Shoal, and undermining Vietnam’s efforts to develop offshore oil and gas fields by blocking Hanoi’s physical access to the sites are among a litany of small successes that expand China’s control and build confidence in its capacity to scale up those efforts.

Pursuing such a gray-zone strategy entails some risks. China must carefully calibrate the timing and extent of its coercive activities to avoid counterproductive reactions from Washington and regional allies. Chinese actions to restrict or sever critical flows of food, fuel, or information to Taiwan, in particular, risk inviting symmetric responses from the United States. But the gray-zone approach also offers distinct advantages. Beijing can rely heavily on law enforcement and civilian assets in its activities against Taiwan, but the United States lacks the nonmilitary maritime forces required to respond in kind. Washington may turn toward economic or diplomatic measures, but these cannot directly reverse China’s physical and operational gains and are unlikely to impose costs sufficient to force China to change course.

The United States has struggled to coordinate effectively with allies and partners to prevent China’s progressively more coercive gray-zone actions. As long as Beijing does not directly impede the flow of commercial traffic through the Taiwan Strait, most countries are likely to remain on the sidelines. Some foreign actors, including China’s regional neighbors and commercial entities such as shipping firms, would likely accommodate many types of new restrictions Beijing might place on Taiwan. Multinational firms have already set a worrisome precedent of deferring to Beijing: Japanese and South Korean firms, for example, have for years deferred to Beijing’s notification rules (as opposed to those set by Taipei) for commercial flights traveling over the Taiwan Strait.

KEY CHANGE

If the United States and Taiwan remain narrowly focused on the Davidson Window, they will make decisions that are poorly matched to China’s more probable strategic choices. Investments in precision munitions and the forward deployment of large numbers of U.S. warships and aircraft in Asia are mismatched against Chinese actions calibrated to stay just beneath the threshold that would make these assets useful. Similarly, Taiwan’s pursuit of high-end military hardware such as submarines and fighter jets and upgraded military training focused on repelling Chinese invaders will do little to impede China’s creeping exercise of coercive control through law enforcement and other nonlethal tactics.

Instead, Taiwan should take the lead in proactively pushing back on China’s encroachment by creating buffer zones that protect its airspace, waters, and economy. Calling attention to Chinese gray-zone operations will not be sufficient on its own. Taiwan would benefit from focusing its defense investments on domain-awareness capabilities—for instance, acquiring more advanced ground- and sea-based sensors to better detect and monitor the presence of Chinese aircraft and ships in nearby airspace and waters. It should also build a large fleet of inexpensive air and sea drones that could support surveillance operations in Taiwan’s outlying areas and respond to the staggering scale of Chinese incursions at reasonable cost. Taiwan must also expand its coast guard to more assertively push back against the activities of China’s coast guard and maritime militia. Taipei has made some modest steps in these directions but is moving far too slowly to meet the challenges posed by China’s intensifying campaign. Taiwan will need to quickly increase its spending on the development of indigenous capabilities and focus any foreign military financing from the United States on these types of systems.

In the information domain, Taiwan should harden its communication systems and train a more sophisticated cyberdefense workforce. Even more important, Taiwan must accelerate its efforts to expand and diversify its satellite communications services and infrastructure to defend against Chinese attacks on its information networks and submarine Internet cables. Already, Taiwan has signed a contract with Eutelsat OneWeb—an analog to the Starlink system that has proved so vital in Ukraine—but it should take further steps to augment satellite bandwidth in the near term.

If Washington remains narrowly focused on the prospect of an invasion of Taiwan, it will make mistakes.

Washington will also be crucial to Taiwan’s buffer zone strategy. In April, Congress earmarked $2 billion for defense aid to the Indo-Pacific, but how this money will be allocated remains unclear. The United States should use a portion of available funds to bolster Taiwan’s aerial and maritime surveillance and intelligence capabilities and its fleets of air, sea, and subsurface drones. Washington should also consider an expanded role for the U.S. Coast Guard in and around the Taiwan Strait. Currently, U.S. Coast Guard forces patrol the exclusive economic zones of U.S. allies such as Japan and the Philippines, uphold the international Law of the Sea, and engage in exercises with regional partners. Extending the Coast Guard’s mandate in waters near Taiwan to include, for example, patrolling nearby fisheries with the aim of ensuring access and supporting resource conservation could push back against China’s efforts to control these areas while matching Beijing’s use of law enforcement vessels. Using Coast Guard vessels is less likely to provoke escalation than employing the U.S. Navy and better suits a policy aimed at preserving the fragile status quo.

Finally, the United States ought to coordinate with corporations to support Taiwan’s economic buffer, especially those that ship goods to the island via sea and air. An interagency group from the Departments of Defense, Homeland Security, and State should establish channels to assess emerging risks and share early warning indicators with the leaders of large multinational trading firms, shippers, and insurers. This exercise should be conducted in a private setting to facilitate contingency planning and provide governmental and military support for these corporations to undertake physical and financial preparations that will ensure Taiwan’s access to global markets.

If the best predictor of future behavior is past behavior, the United States and Taiwan should be as focused on developing strategies to prevent Taiwan’s slow subjugation as they are on forestalling outright invasion. If Washington cannot alter its single-minded outlook, it could end up as a bystander as Taiwan slips under creeping Chinese control in a silent fait accompli.
