Why the Battle for Taiwan Is Older Than You Think

To understand why Taiwan is contested, start with the end of the Chinese civil war. On October 1, 1949, Chinese Communist leader Mao Zedong declared the founding of the People's Republic of China in Beijing. The declaration ended a full-scale civil war against the Nationalist Party (Kuomintang). That war had resumed after World War II.

The losing side did not surrender. It relocated. Nationalist leader Chiang Kai-shek and his forces fled to Taiwan to regroup and plan to retake the mainland. The island sits about 100 miles off the coast of Fujian Province. The Taipei Times reported that roughly 1.2 million people made the crossing.

Two governments now claimed the same country. The Republic of China ruled only Taiwan and a few smaller islands but still called itself China. The People's Republic of China ruled the mainland and called itself Real China. The State Department notes that the United States backed the losing side for decades. Initially, Washington recognized the Republic of China on Taiwan as China's government. It supported that government's seat at the United Nations until the 1970s.

For the people of Taiwan, the new arrival was not liberation. The Global Taiwan Institute records that after World War II, the island endured 38 years of martial law beginning in 1949. Civil rights were severely restricted throughout those years. The security apparatus of that era detained, tortured, and killed dissidents in a period later named the "White Terror."

Then, Washington switched sides on paper. The Jimmy Carter administration recognized the People's Republic of China as the sole legal government of China on January 1, 1979. It de-recognized the Republic of China at the same time. The United States acknowledged Beijing's position that Taiwan is part of China without endorsing it. Washington has held that careful distinction ever since.

US Congress refused to abandon Taiwan entirely. In 1979, it passed the Taiwan Relations Act. The United States expects Taiwan's future to be settled by peaceful means. It treats any non-peaceful effort to decide that future as a grave concern. It must also make defensive arms available to Taiwan. The law did not promise that American forces would intervene. That silence became the policy now called "strategic ambiguity."

In 1982, the United States added two more layers. The third United States and China communique of August 17, 1982, stated that Washington did not seek a long-term policy of arms sales to Taiwan. To reassure Taipei, then-President Ronald Reagan separately delivered the "Six Assurances." He pledged, among other points, that the United States had set no date to end arms sales and would not consult Beijing about them. He also pledged that Washington would not pressure Taiwan into negotiations.

Inside Taiwan, the political ground shifted from authoritarian rule to democracy. Both the Global Taiwan Institute and CSIS record the milestones. Martial law was lifted in 1987. Taiwan held its first direct presidential election in 1996, and more than 10 million people voted. A society that had been ruled by one party at gunpoint became a multi-party democracy in a single generation.

That democratization split the old framing of "one China". In 1992, representatives of Beijing and Taiwan's then-ruling Kuomintang reached an understanding that both sides belonged to "one China." The Kuomintang reads that formula as allowing each side its own interpretation. Beijing reads the same understanding as acceptance of the People's Republic. The Democratic Progressive Party, which now governs Taiwan, rejects the formula outright.

The chips came late to this story. The Conversation documents how Taiwan came to dominate the industry. Taiwan's semiconductor industry accelerated in the 1990s when TSMC pioneered the foundry model. Under that model, TSMC manufactured chips to designs owned by foreign companies. Over the following three decades, the island moved from contract manufacturer to the indispensable maker of the most advanced chips on Earth. That rise turned a Cold War leftover into a node the entire global economy now runs through.

1. China (Beijing)

   i. Beijing frames Taiwan as unfinished national business, not a foreign conquest

   The government of the People's Republic of China argues that Taiwan was separated from China by the weakness of the past and that bringing it back completes the nation's recovery. President Xi Jinping has tied the issue directly to what he calls the great rejuvenation of the Chinese nation. He stated that the Taiwan question arose from national weakness and would be resolved as that rejuvenation is achieved. CNBC reported his New Year address delivered on December 31, 2024. In that address, he declared that no one can stop what Beijing calls reunification. From Beijing's vantage, this is the recovery of its own territory. It points to decades of international recognition of the "one China" principle as evidence the world has accepted the claim.

   ii. Beijing argues the legal and historical record supports a single China

   The People's Republic holds that there is one China in the world and that Taiwan is part of it. Most governments formally acknowledge that position to some degree. Beijing's case rests on the record. CSIS documents that the United States itself recognized the People's Republic as the sole legal government of China in 1979. The Republic of China also lost its United Nations seat to Beijing in 1971. In Beijing's view, Taiwan's separate administration is a temporary condition left over from a civil war, not the foundation of a separate state.

2. The United States and its Allies

   i. Washington presents strategic ambiguity as the formula that has kept the peace

   The United States government points to its deliberate refusal to say whether it would defend Taiwan. It argues that ambiguity has deterred both a Chinese attack and a Taiwanese declaration of formal independence for decades. Washington recognizes Beijing, arms Taipei, and treats any non-peaceful change as a grave concern under the Taiwan Relations Act. It says that mix preserves the status quo and lets both sides avoid war. CSIS notes that this understanding has enabled stability in the Taiwan Strait. Both Taiwan and the mainland pursued their own transformations in relative peace.

   ii. Washington and its partners frame Taiwan's defense as protection of a democracy and a vital supply chain

   The United States casts Taiwan as a functioning democracy and a major trading partner whose security underpins American credibility across Asia. It also frames the island's chip industry as a global asset worth shielding. Rest of World reports that TSMC produces about 90 percent of the world's most advanced semiconductors. On this question, Japan is the closest regional ally, and it went further in 2025 than at any point before. The Japanese government stated on November 25, 2025, that peace and stability in the Taiwan Strait are highly important to Japan's own security and the world's. It expressed hope for a peaceful settlement through dialogue.

3. Taiwan (Taipei)

   i. Taipei argues it is already self-governing and that its people must decide

   President Lai Ching-te of the Democratic Progressive Party leads the government in Taipei. That government holds that Taiwan is already a self-governing entity and that the People's Republic has never ruled it. Lai has stated plainly that Taiwan does not belong to the People's Republic of China and that the two governments are not subordinate to each other. Focus Taiwan reported those remarks in May 2026. The Democratic Progressive Party set out its longstanding position in its 1999 resolution: Taiwan's future should be decided by its people alone. The strongest version of Taiwan's case is democratic legitimacy: a government chosen in free elections since 1996 answers to its own voters, not to Beijing.

   ii. Taipei argues it is now paying for its own defense to back its position

   Taiwan's government argues that it is not asking others to carry a burden it will not shoulder. NPR reported President Lai's announcements in November 2025. Defense spending would rise to 3.3 percent of the island's economy by 2026 and toward 5 percent by 2030. A roughly $40 billion special budget would fund new arms and asymmetric capabilities. Taipei frames this as evidence it is serious about deterring an attack rather than relying on a promise of rescue that Washington has never explicitly made.

1. Of China (Beijing)

   i. Critics say Beijing's pressure campaign undercuts its own claim of peaceful intent

   Taipei, Washington, and Tokyo all point to Beijing's military activity as evidence that its talk of peaceful reunification is hollow. The American Enterprise Institute compiled Taiwan's defense ministry data. It shows that Chinese aircraft entered Taiwan's air-defense identification zone more than 3,000 times in the year through October 2025. That was up about 33 percent from the prior year. Beijing conducted large encirclement exercises named "Strait Thunder-2025A" in April 2025 and a blockade-style drill in late December 2025. The same data set records both. The United States Department of Defense addressed the shift in its 2025 annual report to Congress. It assessed that Beijing's dropping of peaceful unification language points to a campaign to compel rather than merely deter. Critics argue that a power confident in its legal case would not need to rehearse a blockade.

   ii. Critics say Beijing offers Taiwan a model its people have already rejected

   Taiwan's government and many of its voters argue that the "one country, two systems" framework Beijing has proposed lost its credibility after Hong Kong. Taipei's Mainland Affairs Council reaffirmed in 2025 that the People's Republic has never ruled Taiwan.

   Taiwanese polling shows scant support for unification. Taiwan Public Opinion Foundation surveys conducted in December 2024 and January 2025 found that 13.3 percent of respondents favored unification with China. Far larger shares preferred independence or the status quo. Critics say Beijing's claim to speak for the Taiwanese people is contradicted by the people themselves.

2. Of the United States and its Allies

   i. Critics say strategic ambiguity may now invite the war it was meant to prevent

   Some analysts and lawmakers argue that the policy of not committing to Taiwan's defense is now dangerous. The policy was designed for an era of Chinese weakness, and China is far stronger today. The objection has appeared in venues such as Foreign Affairs. Ambiguity could lead Beijing to gamble that Washington will not respond. That would turn a deterrent into a temptation. Beijing makes the mirror-image complaint. It argues that American arms sales and high-level contacts already violate the spirit of the "one China" commitments Washington made in 1979 and 1982. It also argues that the United States is the party changing the status quo.

   ii. Critics question whether moving chip production abroad weakens the very island Washington claims to protect

   The argument that TSMC's defining role shields Taiwan is sometimes called the "silicon shield." The shield cuts both ways, and critics in Taiwan have voiced unease about it. TSMC plans to expand its investment in the United States to $165 billion. The company's own filing records that the plan was announced alongside President Donald Trump at the White House on March 3, 2025. The plan drew warnings inside Taiwan that shifting advanced production to Arizona could erode the island's strategic leverage. Skeptics also note that even a large American build-out leaves Taiwan as the critical node for the most advanced chips for years. The relocation may therefore dilute Taiwan's protection without yet replacing its capacity.

3. Of Taiwan (Taipei)

   i. Critics say Taipei's own politics are blocking the defense build-up it promises

   Beijing argues that the Democratic Progressive Party's rejection of the "one China" formula is the real source of instability. In Beijing's view, that rejection removed the diplomatic basis that allowed earlier cross-strait talks. There is also a domestic critique with hard numbers behind it. President Lai's special defense budget has met resistance at home. The opposition-controlled legislature capped the version under consideration at 780 billion New Taiwan dollars, below the proposal. NPR reported that the spending plan faced gridlock in early 2026. Critics across the spectrum say that a divided Taipei sends a mixed signal about its own resolve.

   ii. Critics say Taipei is caught between deterrence and provocation

   Beijing casts every assertion of separate sovereignty by President Lai as a step toward formal independence that could trigger its Anti-Secession Law. That 2005 law sets out three conditions under which Beijing says it could use non-peaceful means: if Taiwan independence forces cause secession, if a major incident entailing secession occurs, or if possibilities for peaceful unification are completely exhausted. Critics on the mainland argue that Taipei's rhetoric pushes toward those red lines. Critics elsewhere counter that the red lines are defined by Beijing alone and can be moved at will. That leaves Taiwan with no safe position to hold.
