One-China Policy and Cross-Strait Relations

The One-China idea is about one simple question: is Taiwan a part of China or not? The People's Republic of China (PRC), which rules mainland China from Beijing, says there is only one China, Taiwan is part of it, and the government in Beijing is its only legal government. Most countries, including India, have formal diplomatic ties only with Beijing, and keep only unofficial ties with Taiwan. "Cross-Strait relations" means the relationship between mainland China and Taiwan, which face each other across the Taiwan Strait.

Why does this question exist at all?

It comes from an unfinished civil war. From the late 1920s, two Chinese groups fought for control of China: the Nationalists (the Kuomintang, led by Chiang Kai-shek) and the Communists (led by Mao Zedong). In 1949, the Communists won on the mainland and set up the People's Republic of China. The defeated Nationalist government moved to the island of Taiwan and kept the old official name, the Republic of China (ROC).

No peace treaty was ever signed. So since 1949 there have been two governments, each once claiming to be the real government of all China.

How did the world choose between them?

At first, many Western countries recognised the ROC in Taipei, and it held China's seat at the United Nations, including the permanent seat in the Security Council. Over time, more countries switched to Beijing.

• On 25 October 1971, the UN General Assembly passed Resolution 2758. It recognised the PRC government as the only lawful representative of China at the UN and removed the representatives of Chiang Kai-shek. The resolution settled who holds China's UN seat. It did not mention Taiwan by name. China reads it as settling Taiwan's status; the US and some others argue it did not decide Taiwan's status.
• After this, most countries moved their recognition to Beijing. As of 2026, only 12 countries have full diplomatic ties with Taiwan (the ROC). Most are small states in Latin America, the Caribbean and the Pacific, plus Eswatini in Africa. The Holy See (Vatican) also recognises Taipei.

Policy vs principle: the most important difference

UPSC loves this trap.

• The One-China Principle is China's own position: there is one China, Taiwan is an inseparable part of it, and the PRC is the sole legal government of China. Beijing asks every country to accept this.
• A One-China Policy is each other country's own version of how it deals with this claim. Many countries word it carefully. For example, they "acknowledge" or "take note of" China's position without saying they agree with it.

So two countries can both say they follow "a One-China policy" and still mean different things.

The US version: three communiqués, one law, six assurances

The United States shapes much of this issue, so its framework matters.

• Shanghai Communiqué (February 1972): Issued during US President Nixon's visit to China. The US said it "acknowledges" that Chinese on both sides of the Strait say there is one China and Taiwan is part of it, and that it does not challenge that position.
• Normalisation Communiqué (1 January 1979): The US recognised the PRC as the sole legal government of China. It cut formal ties with Taipei and ended its 1954 defence treaty with Taiwan, but kept unofficial ties.
• Taiwan Relations Act (TRA), 1979: A US law. It lets the US keep unofficial links with Taiwan and says the US will make available the weapons Taiwan needs for its self-defence.
• August 1982 Communiqué: The US said it would gradually reduce arms sales to Taiwan.
• Six Assurances (1982): Promises given to Taiwan, including that the US had not changed its position on sovereignty over Taiwan.

The US has never clearly said whether it would fight to defend Taiwan. This deliberate vagueness is called strategic ambiguity. The idea is to stop China from attacking and also stop Taiwan from formally declaring independence.

How do Beijing and Taipei talk to each other?

In the early 1990s, both sides created semi-official bodies for talks: the Straits Exchange Foundation in Taiwan and the Association for Relations Across the Taiwan Straits in China. From their 1992 contacts came the so-called 1992 Consensus. Under it, both sides accepted that there is "one China", but each side kept its own reading of what "China" means.

Beijing treats acceptance of the 1992 Consensus as the condition for talks. Taiwan's present ruling party does not accept it, so high-level official dialogue has largely stopped since 2016.

China's legal threat: the Anti-Secession Law, 2005

China's legislature passed the Anti-Secession Law on 14 March 2005. Secession means a region breaking away from a country. Article 8 of the law says China shall use "non-peaceful means" (meaning military force) if Taiwan moves towards formal independence, if a major event leading to separation happens, or if all chances of peaceful reunification are lost. This law is why every step by Taiwan towards a separate identity is watched closely by Beijing.

What is Taiwan's actual status today?

In practice, Taiwan works like a separate country. It has its own elected government, constitution, army, currency (the New Taiwan dollar) and passport. But it lacks wide diplomatic recognition and is not a UN member. Many countries keep "trade offices" or "cultural centres" in Taipei that act like embassies without the name. Most people in Taiwan prefer to keep the present situation, known as the status quo, rather than either formal independence or unification soon.

India's position

India set up diplomatic relations with the PRC on 1 April 1950, among the first non-communist countries to do so. India does not have formal diplomatic ties with Taiwan. Its relations with Taiwan are unofficial but growing:

• In 1995, India set up the India-Taipei Association in Taipei, and Taiwan set up the Taipei Economic and Cultural Center (TECC) in New Delhi. These work like embassies in practice.
• Taiwan opened a second TECC in Chennai (2012) and a third in Mumbai (October 2024). China objected to the Mumbai office.
• Taiwanese companies invest in Indian electronics and semiconductor manufacturing.

For many years, India mentioned support for "one China" in joint statements with Beijing. It has stopped repeating this line in joint statements since around 2010. Reports link this to China's practice of giving "stapled visas" (loose paper visas instead of stamped ones) to Indians from Jammu and Kashmir and Arunachal Pradesh. India's message is that sensitivity on core issues must be mutual. India's officially stated approach is that its ties with Taiwan focus on trade, investment, technology, culture and people-to-people links.

Commonly confused concepts

• PRC vs ROC: The PRC is mainland China (capital Beijing). The ROC is the official name of the government on Taiwan (seat in Taipei). The ROC was the founding UN member; the PRC took over the China seat in 1971.
• One-China Principle vs One-China Policy: Principle is Beijing's claim. Policy is how each other country chooses to respond to it.
• Taiwan Relations Act vs the communiqués: The TRA is a US domestic law passed by Congress. The communiqués are joint diplomatic statements between the US and China.
• Strategic ambiguity vs strategic clarity: Ambiguity means not saying clearly what you will do. Clarity would mean openly promising to defend Taiwan.
• Status quo vs independence: Keeping the status quo means Taiwan stays self-ruled without formally declaring itself a new country. Formal independence would mean declaring a "Republic of Taiwan", which China says it would answer with force.

Issues, criticism and the way forward

• Risk of war: Taiwan is one of the most dangerous flashpoints in the world. A war would involve China, possibly the US and Japan, and would hit the world economy hard.
• Grey-zone pressure: China uses military drills, air incursions, coast guard patrols and trade limits that stay below the level of open war. These slowly wear down Taiwan's defences and morale.
• Diplomatic squeeze: China has pulled away many of Taiwan's diplomatic allies and blocks Taiwan from UN bodies such as the World Health Assembly. Supporters of Taiwan say this harms global cooperation on health and aviation. China says it is a matter of its sovereignty.
• Defence debate inside Taiwan: There is debate over how much to spend, what to buy and how to fund it. Some favour large weapons systems. Others argue for many small, cheap and mobile weapons that are hard to destroy (sometimes called a "porcupine" approach).
• For India: India must balance its growing technology and trade ties with Taiwan against its complex relationship with China, including the border dispute. Experts suggest India deepen economic links (semiconductors, electronics, skills) while keeping its relations unofficial and steady.

Concepts to Know

• Diplomatic recognition: When one country formally accepts another government as the legal government of a state. It usually comes with embassies and ambassadors.
• Communiqué: A formal joint statement issued by two governments after talks. It is a political statement, not a law.
• Sovereignty: The full right of a state to govern itself and its territory without outside control.
• Reunification: China's term for bringing Taiwan under Beijing's rule. Taiwan's government rejects this.
• Grey-zone tactics: Pressure that is more than normal diplomacy but less than open war, such as drills near borders, coast guard patrols or cyber attacks.
• Deterrence: Being strong enough that an enemy decides an attack would cost too much.
