Analyse the Taiwan question in Chinese policy and evaluate why it remains unresolved and so dangerous

What this dot point is asking

SEAB wants you to analyse the Taiwan question in Chinese policy, why China regards Taiwan as central, and to evaluate why it has remained unresolved and why it is so dangerous. The key analytical move is to explain what makes Taiwan unique: it is simultaneously a non-negotiable Chinese "core interest" bound up with national identity and Party legitimacy, an issue in which the United States retains a deep stake, and therefore the most plausible trigger for war between great powers. You should also explain why it has nonetheless been managed for decades. Your judgement should weigh the unique danger of the issue against the framework that has so far kept the peace.

The answer

The origins of the question

The Taiwan question dates from the Chinese Civil War. When the Communists won on the mainland in 1949, the defeated Nationalist (Kuomintang) government retreated to the island of Taiwan, where it continued to claim to be the legitimate government of all China. The result was a divided China: the People's Republic on the mainland and the Republic of China on Taiwan, each historically claiming to represent the whole. Over time Taiwan developed into a prosperous, and eventually democratic, society with its own distinct trajectory, while the People's Republic insisted that Taiwan is a province of China that must ultimately be reunified with the mainland.

The one-China principle

The foundation of Chinese policy is the "one-China principle": the insistence that there is only one China, that Taiwan is an inalienable part of it, and that the People's Republic is its sole legitimate government. China requires other states to accept a version of this principle as the basis for diplomatic relations, which is why most countries recognise Beijing rather than Taipei and why Taiwan has very limited formal diplomatic recognition. Reunification with Taiwan, by peaceful means if possible but without renouncing the use of force, is a stated and enduring goal. The "one country, two systems" formula used for Hong Kong was originally designed with Taiwan in mind as a possible model for reunification.

Why Taiwan is a "core interest"

Taiwan is not just one dispute among many; it is a "core interest" of the highest order, for reasons that make compromise almost impossible. It is bound up with sovereignty and territorial integrity, on which China will not yield. It is tied to national identity and the narrative of the "great rejuvenation of the Chinese nation," in which the recovery of Taiwan is presented as completing the reversal of past humiliation and division. And it is connected to Party legitimacy: having staked its prestige on reunification, the leadership would face a serious blow to its standing if Taiwan were permanently lost or achieved formal independence. For all these reasons, Taiwan touches the most sensitive nerves of the Chinese state, and the leadership treats any move toward Taiwanese independence as an existential red line.

The American factor and strategic ambiguity

What makes Taiwan uniquely dangerous is the involvement of the United States. Although the United States recognises the People's Republic and accepts a "one China" framework, it has maintained a substantial stake in Taiwan, including arms sales and an interest in the island's security, and a long-standing posture of "strategic ambiguity", deliberately leaving unclear exactly how it would respond to a Chinese attack, in order to deter both a Chinese assault and a Taiwanese declaration of independence. This means that a cross-strait crisis is not merely a China-Taiwan matter but a potential trigger for direct conflict between the United States and China, the two leading military powers. No other issue so directly couples a Chinese core interest to the risk of great-power war.

Why it remains unresolved

The strongest answers explain the deadlock. The fundamental obstacle is that China's absolute insistence on reunification collides with the reality on Taiwan, where decades of separate development and democratisation have produced a society increasingly attached to its own distinct, democratic identity and wary of unification, especially after the example of Hong Kong. Neither side can concede: China cannot abandon a core interest tied to legitimacy and identity, and Taiwan's population shows little appetite for absorption. The result is an enduring stalemate, in which the status quo, neither formal independence nor reunification, persists because any decisive move risks catastrophe.

Why it has nonetheless been managed

A balanced evaluation notes that, despite the danger, the question has been managed without war for decades. The "one China" framework provided a formula all sides could live with by leaving the ultimate status deliberately unresolved; strategic ambiguity deterred provocations from both Taipei and Beijing; and dense economic ties across the strait, with extensive trade and investment, gave both sides material incentives to avoid conflict. This management has kept an uneasy peace. But the balance has been shifting: as China's military power has grown and as cross-strait and US-China relations have hardened, the risk has risen, and the durability of the long peace is increasingly questioned.

Weighing the danger

The most accurate judgement is that Taiwan is indeed the most dangerous issue in China's foreign relations, because it uniquely fuses a non-negotiable Chinese core interest, a deep American stake, and a real risk of great-power war, a combination no other dispute matches. It has been managed for decades through the one-China framework, strategic ambiguity and economic interdependence, which counsels against assuming conflict is imminent. But the shifting military balance and hardening relations mean the danger is real and rising, so Taiwan remains the most plausible flashpoint for a war between the great powers.

Examples in context

Example 1. The one-China principle in diplomacy. China requires states to accept a version of the one-China principle as the basis for diplomatic relations, which is why most countries recognise Beijing and why Taiwan has very limited formal recognition and is excluded from many international bodies. This diplomatic isolation of Taiwan is the clearest everyday expression of the one-China principle in action, and it shows how China uses its weight to enforce its position on what it regards as a core matter of sovereignty.

Example 2. Strategic ambiguity and arms sales. The United States, while recognising the People's Republic, continues to sell arms to Taiwan and maintains deliberate ambiguity about whether it would intervene militarily to defend the island. This posture is designed to deter both a Chinese attack and a Taiwanese move to formal independence. It exemplifies why Taiwan is uniquely dangerous: it directly ties a Chinese core interest to the prospect of conflict with the United States, making the strait the most likely site of great-power war.

Try this

Q1. State the one-China principle. [4 marks]

• Cue. That there is only one China, that Taiwan is an inalienable part of it, and that the People's Republic is its sole legitimate government, the basis China requires for diplomatic relations.

Q2. Explain why China treats Taiwan as a "core interest." [12 marks]

• Cue. It is tied to sovereignty and territorial integrity, to the narrative of national rejuvenation reversing past division and humiliation, and to Party legitimacy, so reunification cannot be abandoned.

Q3. "The Taiwan question has been managed for decades and will continue to be." How far do you agree? [20 marks]

• Cue. Argue the one-China framework, strategic ambiguity and economic ties kept an uneasy peace; weigh against the shifting military balance, hardening relations and diverging Taiwanese identity; judge the danger as real and rising despite past management.
