Chinse President Xi Jinping’s (習近平) Chinese Communist Party (CCP) has threatened to invade Taiwan for more than seven decades. Now fears are growing among analysts, officials and investors that it might actually follow through over the next few years, potentially triggering a war with the US.
Last month, Chinese People’s Liberation Army (PLA) aircraft repeatedly breached the median line of the Taiwan Strait, eliminating a de facto buffer zone that has kept peace for decades.
The party-run Global Times newspaper has given a picture of what could come, urging China’s air force to patrol the skies over Taiwan and “achieve reunification through military means” if it fires any shots. Taiwan announced it would only shoot if attacked.

Despite the saber rattling, China and Taiwan have many reasons to avoid a war that could kill tens of thousands, devastate their economies and potentially lead to a nuclear conflict with the US and its allies.
The overwhelming consensus remains that Beijing would continue efforts to control Taiwan through military threats, diplomatic isolation and economic incentives. Equities in Taiwan have in the past few months hit record highs.
However, several forces might push them toward action: Xi’s desire to cement his legacy by gaining “lost” territory, falling support among Taiwan’s public for any union with China, the rise of pro-independence forces in Taipei and the US’ increasingly hostile relationship with Beijing on everything from Hong Kong to COVID-19 to cutting-edge technology.
“I am increasingly concerned that a major crisis is coming,” said Ian Easton, senior director at the Project 2049 Institute who wrote The Chinese Invasion Threat: Taiwan’s Defense and American Strategy in Asia. “It is possible to envision this ending in an all-out invasion attempt and superpower war. The next five to 10 years are going to be dangerous ones. This flash point is fundamentally unstable.”
Taiwan will be among the most pressing security issues facing whoever wins the US presidential election on Nov. 3.
While Taipei has enjoyed a resurgence of bipartisan support in Washington and the administration of US President Donald Trump has made unprecedented overtures, Trump himself has expressed skepticism about Taiwan’s strategic value. Democratic nominee Joe Biden has previously said that Congress should decide whether the US should defend Taiwan in any attack.
Analysts such as Easton have gamed out scenarios of a potential Chinese invasion of Taiwan for years, based on military exercises, arms purchases and strategy documents from the major players. Most of them foresee China going for a quick knockout, in which the PLA overwhelms the main island before the US could help out.
On paper, the military balance heavily favors Beijing. China spends about 25 times more on its military than Taiwan, according to estimates from the Stockholm International Peace Research Institute, and has a clear conventional edge on everything from missiles and fighter jets to warships and troop levels — not to mention its nuclear arsenal.
Beijing’s optimistic version of events goes something like this: Prior to an invasion, cyber and electronic warfare units would target Taiwan’s financial system and key infrastructure, as well as US satellites to reduce notice of impending ballistic missiles.
Chinese vessels could also harass ships around Taiwan, restricting vital supplies of fuel and food.
Airstrikes would quickly aim to kill Taiwan’s top political and military leaders, while also immobilizing local defenses. The Chinese military has described some drills as “decapitation” exercises, and satellite imagery shows its training grounds include full-scale replicas of targets such as the Presidential Office Building in Taipei.
An invasion would follow, with PLA warships and submarines traversing some 130km across the Taiwan Strait. Outlying islands such as Kinmen and the Pratas Islands (Dongsha Islands, 東沙群島) could be quickly subsumed before a fight for the Penghu archipelago, which sits just 50km from Taiwan proper and is home to bases for all three branches of the military.
A PLA win here would provide it with a valuable staging point for a broader attack.
As Chinese ships speed across the Strait, thousands of paratroopers would appear above Taiwan’s coastlines, looking to penetrate defenses, capture strategic buildings and establish beachheads through which the PLA could bring in tens of thousands of soldiers who would secure a decisive victory.
In reality, any invasion is likely to be much riskier. Taiwan has prepared for one for decades, even if lately it has struggled to match China’s growing military advantage.
Taiwan proper has natural defenses: Surrounded by rough seas with unpredictable weather, its rugged coastline offers few places with a wide beach suitable for a large ship that could bring in enough troops to subdue its 24 million people.
The mountainous terrain is riddled with tunnels designed to keep key leaders alive, and could provide cover for insurgents if China established control.
Taiwan in 2018 unveiled a plan to boost asymmetric capabilities like mobile missile systems that could avoid detection, making it unlikely Beijing could quickly destroy all of its defensive weaponry.
With thousands of surface-to-air missiles and anti-aircraft guns, Taiwan could inflict heavy losses on a Chinese invasion force before it reached the main island.
Taiwan’s military has fortified defenses around key landing points and regularly conducts drills to repel Chinese forces arriving by sea and from the air.
In July, outside of the western port of Taichung, Apache helicopters, F-16s and the nation’s domestically developed fighter jets sent plumes of seawater into the sky as they fired offshore, while M60 tanks, artillery guns and missile batteries pummeled targets on the beach.
Chinese troops who make it ashore would face roughly 175,000 full-time soldiers and more than 1 million reservists ready to resist an occupation. Taiwan this week announced it would set up a defense mobilization agency to ensure they were better prepared for combat, the Taipei Times reported.
Other options for Beijing, such as an indiscriminate bombing campaign that kills hundreds of thousands of civilians, would hurt the CCP’s ultimate goal of showcasing Taiwan as a prosperous territory with loyal Chinese citizens, Michael Beckley, who has advised the Pentagon and US intelligence communities, wrote in a 2017 paper.
“The PLA clearly would have its hands full just dealing with Taiwan’s defenders,” Beckley wrote. “Consequently, the United States would only need to tip the scales of the battle to foil a Chinese invasion.”
The potential involvement of the US is a key wild card when assessing an invasion scenario.
US naval power has long deterred China from any attack, even though the US scrapped its mutual defense treaty with Taiwan in 1979 as a condition for establishing diplomatic ties with Beijing. The Taiwan Relations Act authorizes US weapons sales to “maintain a sufficient self-defense capability.”
Failing to intervene could hurt US prestige on a scale similar to the UK’s failed bid to regain control of the Suez Canal in 1956, Ray Dalio, the billionaire founder of Bridgewater Associates, wrote on Sept. 25.
That crisis accelerated the disintegration of the British Empire and signaled the pound’s decline as a reserve currency in favor of the US dollar, Dalio said.
“The more of a show the US makes of defending Taiwan, the greater the humiliation of a lost war,” he said. “That is concerning because the United States has been making quite a show of defending Taiwan while destiny appears to be bringing that closer to a reality.”
China’s “Anti-Secession” Law is vague on what would actually trigger an armed conflict.
Its state-run media have warned that any US military deployment to Taiwan would trigger a war — one of several apparent red lines, along with a move for Taipei’s government to declare legal independence. State broadcaster CCTV warned that “the first battle would be the last battle.”
Since the CCP’s legitimacy is based in part on a pledge to “unify” China, its hold on the country’s 1.4 billion people could weaken if it allowed Taiwan to become an independent country.
While any invasion, even of outlying islands, carries the risks of economic sanctions or a destabilizing conflict, threats issued in state-run media allow Beijing to appeal to a domestic audience and deter Taiwan at the same time.
The PLA Air Force last month released a video showing H-6 bombers making a simulated strike on a runway that looked like one at Anderson Air Force Base on Guam, a key staging area for any US support for Taiwan.
The Global Times reported that China’s intermediate ballistic missiles such as the DF-26 could take out US bases, while its air defenses shoot down incoming firepower.
This is a worry for US military planners. A University of Sydney study last year warned that the US “no longer enjoys military primacy” over China and that US bases, airstrips and ports in the region “could be rendered useless by precision strikes in the opening hours of a conflict.”
“Beijing’s strategy isn’t just based on undermining Taiwan’s resistance, it’s also a gamble on how the US will approach the cross-strait issue,” Daniel Russel, a former top US Department of State official under former US president Barack Obama, said in Taipei on Sept. 8. “The strongest driver of increased Chinese assertiveness is the conviction that the Western system, and the US in particular, is in decay.”
In August, China fired four missiles into the South China Sea capable of destroying US bases and aircraft carriers.
Since the DF-26 can be armed with both nuclear and conventional warheads, arms-control experts have worried that any signs China was mobilizing to fire one could trigger a preemptive US strike against Chinese nuclear forces — potentially leading to an uncontrollable conflict.
Whether the world will ever get to that moment largely hinges on political leaders in Beijing and Washington.
Some in the US, like Trump’s former national security adviser, John Bolton, wanted the administration to do much more to show it would come to Taiwan’s aid.
Council on Foreign Relations president Richard Haass last month said that the US should explicitly state it would intervene to deter Xi and reassure allies.
“Above all, Xi is motivated by a desire to maintain the CCP’s dominance of China’s political system,” Haass wrote in Foreign Affairs magazine on Sept. 2, in a piece coauthored with David Sacks. “A failed bid to ‘reunify’ Taiwan with China would put that dominance in peril, and that is a risk Xi is unlikely to take.”
China’s military last month said that it would defeat Taiwan independence “at all cost.”
China’s Taiwan Affairs Office spokesman Ma Xiaoguang (馬曉光) separately warned that President Tsai Ing-wen’s (蔡英文) pro-independence Democratic Progressive Party (DPP) was “totally misjudging” the situation.
Taiwanese officials have also said that China’s military threat is rising, even though Minister of National Defense Yen De-fa (嚴德發) on Tuesday last week told lawmakers that there is no sign the PLA is amassing troops for an invasion.
“We simply have to be prepared for the worst,” said Enoch Wu (吳怡農), a former officer in Taiwan’s special forces who is with the New Frontier Foundation, which is affiliated with the DPP. “China is no longer ‘biding its time’ and no longer trying to win hearts and minds.”
Ultimately, Xi would need to order any attack. Last year, he said that “peaceful reunification” would be best, even though he would not “renounce the use of force.”
He called Taiwan’s integration with China “a must for the great rejuvenation of the Chinese nation in the new era” — a key reason he has used to justify scrapping presidential term limits in becoming China’s most powerful leader since Mao Zedong (毛澤東).
While an invasion carries enormous risks for the party, Xi has shown he would take strong action on territorial disputes.
He has ignored international condemnation in squashing Hong Kong’s pro-democracy camp, militarizing contested South China Sea land features and setting up re-education camps for more than 1 million Uighurs in Xinjiang.
That record worries analysts like Easton, who wrote the book on China’s invasion threat.
“Taiwan fighting by itself could make Beijing pay a terrible price, at least several hundreds of thousands in casualties,” he said. “But that may be a price Xi Jinping is willing to pay. We underestimate the CCP’s capacity for radical decisionmaking at our peril.”
In the closing weeks of 2000, an army of Singaporean government officials descended on Washington to make good on a handshake between then-US President Bill Clinton and Singaporean Prime Minister Goh Chok Tong (吳作棟). They had agreed to strike an FTA after a round of golf in Brunei that past November. Running a small city-state, Singapore’s leaders and their diplomats live with their ear to the ground, attuned to the slightest geopolitical movements. They were motivated then by a big-picture strategic concern — keeping the US embedded in their region. An FTA they thought would help do that. It worked. Clinton’s successor,
On Oct. 7, the Chinese embassy in New Delhi sent letters to the Indian media asking them to refrain from calling Taiwan a country while reporting on its 109th National Day, which fell on Saturday last week. This move backfired and, on the contrary, contributed to the immense popularity of Taiwan among Indians, leading to an outpouring of congratulations for it on Twitter. Asked about the letter, the Indian Ministry of External Affairs said: “There is a free media that reports on issues as it sees fit.” Bharatiya Janata Party spokesman Tajinder Singh Bagga put up several banners outside the
Next month, on Nov. 3, US voters will go to the polls to pick their next president, a choice between former vice president Joe Biden and President Donald Trump, who is seeking a second term. Residents of Taiwan have to wonder how the two will differ in terms of the US’ future Taiwan policy and which will be better for Taiwan. What stands out about the former vice president is how little he has said about Taiwan, and that information about his views or his polices about US-Taiwan relations should be so scarce. That is unusual given that Biden has served in government
In her Double Ten National Day address, President Tsai Ing-wen (蔡英文) took pride in making the claim that this year belongs to Taiwan — “2020 proud of Taiwan.” The essence of this sentimental assertion lies in the fact that this year has seen Taiwan beating its COVID-19 outbreak at the initial stage; it has witnessed Taiwan ducking the negative economic impact of the outbreak — its economy is doing rather well — and it has been a witness to David (Taiwan) taking on Goliaths (China and the WHO). This year, Taiwan has exposed to the world how power politics can
