1. UN Charter and Membership Criteria (basic)
Welcome to our first step in understanding the global architecture of peace! To understand the United Nations (UN), we must start at its birth. The UN was established on October 24, 1945, through the signing of the UN Charter. Think of the Charter as the "Constitution" of the international community. It was initially signed by 51 founding states with a clear, urgent objective: to prevent the kind of catastrophic international conflicts seen during the World Wars and to facilitate cooperation among nations Contemporary World Politics, Chapter 4, p.50. Unlike its predecessor, the League of Nations, the UN was designed to be more inclusive and robust in handling both security and socio-economic development.
Membership in the UN has grown significantly over the decades, reflecting the wave of decolonization and the emergence of new sovereign states. By 2011, the number of member states reached 193, encompassing almost all independent countries in the world Contemporary World Politics, Chapter 4, p.50. In the General Assembly, the UN follows a strictly egalitarian principle: one state, one vote. This means that whether a country is a global superpower or a small island nation, its vote carries the same weight in the Assembly. However, the question of "who" represents a nation can be complex. While the UN aims to represent the people of the world, there is an ongoing debate about whether only democratic leaders should be allowed to represent their countries, as some argue that dictators cannot truly speak in the name of their people Contemporary World Politics, Chapter 4, p.50.
A fascinating and critical aspect of UN membership history is the case of China. While the Republic of China (Taiwan) was a founding member and a permanent member of the Security Council, a major shift occurred in 1971. Through UN General Assembly Resolution 2758, the UN recognized the People’s Republic of China (PRC) as the only legitimate representative of China. Consequently, Taiwan was expelled and is currently not a member of the UN, as the organization considers it an integral part of China rather than a separate sovereign state. This distinguishes Taiwan from other long-standing members like Australia (a founding member), Greece, or Portugal, which are fully recognized sovereign states within the 193-member list.
1945 — UN Charter signed by 51 founding members.
1971 — Resolution 2758: PRC recognized; Taiwan (ROC) loses UN seat.
2011 — UN membership reaches 193 states (with the admission of South Sudan).
As the UN aged, discussions about reform became prominent. During the 60th-anniversary summit in 2005, leaders reviewed the criteria for how the UN—specifically the Security Council—should evolve. Proposed criteria for new members include being a major economic or military power, a substantial contributor to the UN budget, a large population, and a commitment to democracy and human rights Contemporary World Politics, Chapter 4, p.53.
Key Takeaway The UN Charter is the foundational treaty that transformed a group of 51 founding states into a near-universal global body of 193 members, where every sovereign state holds an equal vote in the General Assembly.

2. Core Organs of the UN and Their Functions (basic)
To understand the United Nations, think of it not just as a building in New York, but as a vast machinery with six specialized parts, or
'Principal Organs'. When the UN was established on 24 October 1945, these organs were designed to ensure that no single aspect of global governance—whether it be law, security, or social welfare—was left to chance
History , class XII (Tamilnadu state board 2024 ed.), The World after World War II, p.252. Each organ has a distinct personality and role, ranging from a 'world parliament' to a 'global courtroom.'
The most visible organs are the
General Assembly (UNGA) and the
Security Council (UNSC). The General Assembly is the truly democratic heart of the UN; it is the only body where all 193 member states have equal representation and one vote each. In contrast, the Security Council is the 'executive' arm responsible for maintaining international peace and security. It consists of 15 members, including five permanent members (P5) who hold the power of
veto—a single 'no' vote from any of them can block a resolution
Contemporary World Politics, Textbook in political science for Class XII (NCERT 2025 ed.), International Organisations, p.60. While the GA makes recommendations, the Security Council’s decisions are legally binding on all members.
Beyond security, the UN handles the complexities of human life through the
Economic and Social Council (ECOSOC), which coordinates the work of various specialized agencies like WHO and UNESCO
History , class XII (Tamilnadu state board 2024 ed.), The World after World War II, p.252. The legal disputes between nations are settled by the
International Court of Justice (ICJ), based in The Hague. Supporting all of them is the
Secretariat, the administrative backbone led by the Secretary-General, who manages the day-to-day operations of the UN across the globe.
| Organ | Primary Function | Key Characteristic |
|---|
| General Assembly | Main deliberative and policy-making body. | Universal representation (193 members). |
| Security Council | Maintenance of international peace and security. | P5 members hold Veto power. |
| ECOSOC | Coordination of economic, social, and environmental issues. | Works with specialized agencies (e.g., UNICEF, WHO). |
| Secretariat | Administrative and day-to-day operations. | Headed by the Secretary-General. |
| ICJ | Principal judicial organ. | Settles legal disputes between States. |
| Trusteeship Council | Supervised trust territories (now inactive). | Suspended operations in 1994. |

3. Statehood and Recognition in International Law (intermediate)
In international law, the concept of a
state is built on the foundation of
sovereignty. To be considered a sovereign state, an entity must typically possess four key attributes: a permanent population, a defined territory, a functioning government, and the capacity to enter into relations with other states. As noted in constitutional studies, a sovereign state is independent, with no authority above it, and is free to conduct both its internal and external affairs
Indian Polity, M. Laxmikanth, Preamble of the Constitution, p.43. This external dimension is often manifested through
diplomatic power, where the Head of State represents the nation in international affairs and appoints representatives to other countries
Introduction to the Constitution of India, D. D. Basu, The Union Executive, p.213.
However, having the
physical attributes of a state does not always guarantee
recognition by the international community. There is often a tension between the principle of
national self-determination—the right of a group to see itself as a distinct nation—and the practical reality of whether that group can form a politically and economically viable state
Political Theory, Class XI (NCERT 2025 ed.), Nationalism, p.109. In the eyes of the United Nations, recognition is a collective political act. An entity might function like a state (with its own laws and military), but if the majority of UN member states do not recognize its sovereignty, it may be excluded from formal membership and diplomatic protections.
The case of Taiwan (the Republic of China) illustrates this complex interplay. Taiwan was actually a founding member of the UN and held a permanent seat on the Security Council. However, in 1971, through Resolution 2758, the UN General Assembly recognized the People's Republic of China (PRC) as the only legitimate representative of China. Consequently, Taiwan was expelled and is currently not recognized as a separate sovereign state by the UN, despite functioning independently in practice. This highlights that while membership in the UN does not limit a state's sovereignty Indian Polity, M. Laxmikanth, Preamble of the Constitution, p.43, the UN's recognition is the ultimate 'certificate' of legitimacy in the modern international system.
| Concept |
Description |
| Internal Sovereignty |
The state's supreme authority over its own territory and population. |
| External Sovereignty |
Independence from foreign control and the capacity to act as a legal person internationally. |
| Recognition |
The formal acknowledgement by other states that an entity possesses the attributes of statehood. |
Key Takeaway Statehood requires a mix of objective criteria (territory, population, government) and subjective recognition by the international community, primarily through the United Nations system.

4. Non-Member Observer States and Entities (intermediate)
While the United Nations is a nearly universal organization with
193 Member States Contemporary World Politics, Chapter 4, p.53, its structure allows for a specialized tier of participation known as
Permanent Observer Status. This status is designed for entities that possess sovereign-like qualities or international recognition but, for political or legal reasons, do not hold full membership. These observers can attend sessions, make statements, and participate in debates of the General Assembly, but they
cannot vote on resolutions or nominate candidates for UN offices.
Currently, the UN recognizes only two
Non-Member Observer States: the
Holy See (Vatican City) and the
State of Palestine. The Holy See, recognized as a sovereign entity since the Lateran Treaty of 1929
History (Tamilnadu State Board), Imperialism and its Onslaught, p.212, maintains observer status primarily to preserve its religious neutrality in global political conflicts. Palestine, on the other hand, was upgraded from an 'entity' to a 'non-member observer state' in 2012, reflecting its quest for full international statehood despite ongoing geopolitical complexities.
A unique and more complex case is that of
Taiwan (the Republic of China). It is important to remember that Taiwan was actually a
founding member of the UN and held a permanent seat on the Security Council until 1971. However, following
General Assembly Resolution 2758, the UN recognized the People's Republic of China (PRC) as the only legitimate representative of China
Contemporary World Politics, Chapter 4, p.50. Consequently, Taiwan was expelled and currently holds neither membership nor official observer status, as it is viewed by the UN as an integral part of China.
| Feature | Full Member State | Non-Member Observer State |
|---|
| Voting Rights | Yes, in the General Assembly | No |
| Right to speak | Yes | Yes |
| Examples | India, Australia, Brazil | Holy See, Palestine |
Key Takeaway Non-Member Observer States like the Holy See and Palestine can participate in UN debates but do not have the power to vote, whereas Taiwan is entirely excluded from the UN system following the 1971 resolution.

5. India’s Engagement and Demand for UN Reforms (exam-level)
As a founding member of the United Nations, India’s engagement has evolved from a focus on decolonization and anti-apartheid to a forceful demand for
comprehensive structural reform. India’s core philosophy is that the UN must reflect the
contemporary political realities of the 21st century rather than the post-WWII landscape of 1945. India argues that a revitalized UN is essential for maintaining international peace, but this cannot be achieved as long as the
UN Security Council (UNSC) remains an exclusive club with a static composition that ignores the rise of the Global South
Contemporary World Politics, International Organisations, p.57.
India’s demand for a permanent seat on the UNSC is built on a robust set of credentials. It is the world’s largest democracy, a major economic power, and possesses a strategic location and a vibrant diaspora that enhances its global influence
Geography of India, India–Political Aspects, p.58. Crucially, India is one of the
largest troop contributors to UN Peacekeeping missions, demonstrating its commitment to 'cooperative security' through action rather than just rhetoric
Contemporary World Politics, Security in the Contemporary World, p.77. Beyond security, India advocates for
development to be central to the UN's agenda, viewing socio-economic progress as a vital precondition for lasting global peace.
The debate over membership and representation remains a sensitive political issue within the UN. While India seeks to expand the 'high table' of the Security Council, the UN continues to grapple with questions of statehood and legitimacy. For instance, the
Resolution 2758 (1971) fundamentally altered the UN's composition by recognizing the People's Republic of China as the only legitimate representative of China, leading to the expulsion of Taiwan, which the UN now considers an integral part of China
Contemporary World Politics, International Organisations, p.50. This underscores the 1992 General Assembly resolution's complaint that the Council's decisions often reflect only
Western values and interests rather than equitable global representation
Contemporary World Politics, International Organisations, p.52.
1945 — India joins the UN as a founding member.
1971 — UN Resolution 2758 recognizes the PRC; Taiwan's status as a non-member is solidified.
1992 — UN General Assembly adopts a resolution highlighting the UNSC's lack of representation.
1997 — Secretary-General Kofi Annan initiates an inquiry into reform criteria (Economic/Military power, population, etc.).
Key Takeaway India seeks UN reform to ensure the Security Council reflects modern demographics and economic shifts, arguing that legitimacy depends on equitable representation.

6. The 'Two Chinas' Issue and Resolution 2758 (exam-level)
The 'Two Chinas' issue is one of the most unique diplomatic puzzles in the history of the United Nations. To understand it, we must go back to the
Chinese Civil War. In 1949, the Communist Party of China (CPC), led by Mao Zedong, took control of mainland China and established the
People's Republic of China (PRC). Meanwhile, the defeated Nationalist government (Kuomintang or GMD), led by
Chiang Kai-shek, fled to the island of Taiwan, taking with them gold reserves and cultural treasures, where they continued to call themselves the
Republic of China (ROC) Themes in world history, History Class XI (NCERT 2025 ed.), Paths to Modernisation, p.174. For the next 22 years, despite ruling only a small island, the ROC (Taiwan) continued to hold China's seat at the UN, including its powerful permanent seat on the Security Council.
The tide turned dramatically during the Cold War as the geopolitical landscape shifted. In October 1971, the UN General Assembly passed
Resolution 2758. This resolution did not simply 'admit' a new country; it 'recognized' the representatives of the PRC as the
only legitimate representatives of China to the UN and 'expelled' the representatives of Chiang Kai-shek. This effectively shifted the legal identity of 'China' in the UN system from Taipei to Beijing. Since then, the UN has viewed Taiwan as an integral part of China rather than a separate sovereign state
Contemporary World Politics, Textbook in political science for Class XII (NCERT 2025 ed.), International Organisations, p.50.
Today, while Taiwan functions as a self-governing entity with its own economy and democracy, it remains outside the UN's 193 member states. Most countries do not maintain full official diplomatic relations with Taiwan because doing so would conflict with the 'One China' principle held by the PRC
Themes in world history, History Class XI (NCERT 2025 ed.), Paths to Modernisation, p.175. However,
'Cross-Strait' relations (between mainland China and Taiwan) continue to be a major focus of international trade and security, as seen in the massive Taiwanese investments in the mainland.
| Feature | Republic of China (ROC) | People's Republic of China (PRC) |
|---|
| Location | Taiwan | Mainland China |
| UN Status (Pre-1971) | Held the 'China' seat and Veto power | Not represented in the UN |
| UN Status (Post-1971) | Expelled from the UN | Recognized as the sole representative of China |
1949 — Communist victory; GMD flees to Taiwan and establishes the ROC.
1971 — UN Resolution 2758 recognizes the PRC and expels ROC representatives.
Present — Taiwan remains a non-member of the UN, though it is a major economic player.

7. Solving the Original PYQ (exam-level)
This question bridges your understanding of sovereignty and the evolution of international organisations. Having just studied the structure of the United Nations, you know that membership is reserved for sovereign states recognized by the international community. This specific PYQ tests your ability to apply the historical context of the Cold War and the concept of diplomatic recognition to the UN's current membership list, as detailed in Contemporary World Politics, Textbook in political science for Class XII (NCERT).
To arrive at the correct answer, you must recall the pivotal shift that occurred in 1971. Although the Republic of China (Taiwan) was a founding member and even held a permanent seat on the Security Council, UN General Assembly Resolution 2758 changed its status by recognizing the People’s Republic of China (PRC) as the only legitimate representative of China. Consequently, (B) Taiwan was expelled and is currently considered by the UN as an integral part of China rather than a separate member state. This makes it the correct answer, as it remains the only entity in the list without a seat in the General Assembly.
UPSC often includes countries like Australia, Greece, and Portugal as distractors because they are well-established, democratic nations. The trap here is to assume that because Taiwan is a high-income, democratic economy, it must have formal UN status. However, as noted in the UN Protocol and Liaison Service, there are exactly 193 member states today. Australia is a founding member, and the European options are long-standing members. Always remember: in the UPSC context, political status and legal recognition trump economic or functional statehood.
