June 26, 1945 - China Signs the United Nations Charter in San Francisco

On June 26, 1945, you'd have witnessed China make history by signing the United Nations Charter first in San Francisco—not through political maneuvering, but simply because "China" came first alphabetically among the fifty founding nations. Wu Yi-fang signed on China's behalf at the Veterans' War Memorial Building, where over 3,500 delegates had gathered. The Charter wouldn't become binding law until October 24, 1945. There's far more to this landmark moment than the signing order alone.

Key Takeaways

• On June 26, 1945, representatives from 50 nations signed the United Nations Charter at Veterans Auditorium in San Francisco.
• China signed the Charter first, as signing order followed alphabetical precedence, emphasizing equality among founding member states.
• Wu Yi-fang signed first for China, symbolizing the nation's foundational role in the postwar international order.
• China's delegation notably included both Nationalist and Communist representatives, signaling national unity despite ongoing civil tensions.
• The Charter formally entered into force on October 24, 1945, after sufficient ratifications were deposited by member states.

Why China Was the First to Sign the UN Charter

When China signed the United Nations Charter on June 26, 1945, it did so first — not by political maneuvering or diplomatic privilege, but simply because "China" comes first alphabetically among the founding member states. This alphabetical precedence determined the signing sequence, placing China at the top of the official document ahead of all other nations.

You might assume this position carried deliberate diplomatic symbolism, but the protocol actually emphasized equality among founding states. No country received special treatment in the signing order. Still, landing first on the Charter reinforced China's foundational role in building the postwar international order.

Wu Yi-fang, President of Ginling College and a Chinese delegate, made history by signing her name first — an enduring reminder of China's early commitment to UN principles. The Chinese delegation at San Francisco was notably inclusive, with Dong Biwu attending as a representative of the Communist Party of China and member of the official government delegation. Decades later, Resolution 2758 formally restored the People's Republic of China's lawful seat in the United Nations, recognizing it as the sole legal government of China. Much like the Gatorade shower tradition that began in 1984, small ceremonial moments — such as the order of signatures — can evolve into enduring cultural symbols that carry far greater historical weight than anyone anticipated at the time.

How 50 Nations United Against the Axis in San Francisco

From April 25 to June 26, 1945, fifty nations gathered in San Francisco for the United Nations Conference on International Organization, assembling over 3,500 delegates and staff to build the framework of a postwar world.

Despite divisions in race, religion, language, and culture, these nations shared one common commitment: collective security against Axis aggression.

You'd find that postwar diplomacy demanded unity across vastly different governments, all bound by their adherence to the Atlantic Charter and the 1942 Declaration by United Nations.

Maritime coordination among Allied powers had already proven essential during wartime, and that same collaborative spirit carried into the conference halls.

Eight hundred fifty delegates represented nations actively at war with Axis powers, turning shared sacrifice into the foundation of an entirely new international order. Japan, which had forfeited its 1940 Olympic hosting rights just years earlier due to its military campaigns against China and broader Axis alignment, was notably absent from the founding signatories. The final plenary session on June 25 resulted in a unanimous adoption of the Charter, confirmed by delegations standing rather than a traditional show of hands.

What Collective Security Actually Means in the UN Charter

Beneath the diplomatic language of the UN Charter lies a straightforward but revolutionary idea: an attack on one member state is an attack on all.

When you examine the Charter's structure, you'll find collective obligations distributed across several key articles. Article 2(4) prohibits force. Article 39 empowers the Security Council to identify aggressors. Articles 41 and 42 provide the enforcement mechanisms — ranging from economic sanctions to full military action.

Article 51 still preserves your right to self-defense, but only until the Security Council intervenes.

Unlike old-fashioned bilateral alliances, this system demands universal participation. The aggressor faces collective repulsion, not just retaliation from the targeted state.

China's signature helped transform this framework from diplomatic theory into binding international law. The Charter's architects were driven by the staggering cost of the just-ended conflict, which had claimed forty million lives, making the case for collective security impossible to ignore.

Article 43(1) envisioned member states making armed forces directly available to the Security Council through special agreements, but those agreements never materialized, leaving enforcement dependent on ad hoc coalitions and state-led operations instead.

The principle of judicial accountability over decision-making bodies has similarly evolved in domestic legal systems, as seen when Dunsmuir v. New Brunswick reshaped how Canadian courts review administrative decisions in 2008.

Who Represented China at the UN Charter Signing?

China's delegation at the San Francisco signing ceremony wasn't a monolithic bloc — it was a carefully assembled coalition reflecting the country's fractured political reality. You'll notice the Chinese delegation included both Nationalist and Communist representation, signaling an uneasy but deliberate unity.

Four key signers shaped China's historic moment:

1. V. Wellington Koo — signed on behalf of the Chinese government
2. Wu Yi-fang — President of Ginling College and People's Political Council member
3. Wei Tao-ming — China's Ambassador to the United States
4. Dong Biwu (Tung Pi-wu) — Communist representative, reflecting controlled zones and forces

China signed first, recognizing it as the initial victim of Axis aggression. Dong Biwu's inclusion wasn't incidental — it was strategic, projecting national cohesion despite escalating civil tensions. The signing ceremony itself took place at the Veterans' War Memorial Building, anchoring this diplomatic milestone to a location steeped in the memory of sacrifice. The broader conference that produced the Charter brought together fifty participating nations, convening over two months of intensive diplomatic work in San Francisco.

What Happened Inside the Veterans' War Memorial Building That Day?

On June 26, 1945, delegates from 50 nations packed the Veterans Auditorium inside San Francisco's Veterans' War Memorial Building at 401 Van Ness Avenue to witness history.

The auditorium ceremonies unfolded on stage, where U.S. Secretary of State Edward Reilly Stettinius Jr. signed first as chairman of the American delegation, with President Harry S. Truman standing at his left.

Each nation's representative then stepped forward, delegate handshakes exchanging across a room charged with postwar hope.

The Charter itself had passed unanimously the previous day, June 25, making the signing a formal seal on two months of intensive drafting.

Plenary sessions had run in the adjacent War Memorial Opera House, but this auditorium stage became the true birthplace of the United Nations. Among the signatories was the Earl of Halifax, who signed on behalf of the United Kingdom as Ambassador to the United States. A California Historical Landmark plaque commemorating this distinction now stands in the Veterans Building lobby.

Much like the Toronto Trades and Labour Council organized labour's milestone 1882 parade that spurred formal government recognition of workers across Canada, the United Nations Charter signing represented a pivotal moment of institutional recognition—this time on a global scale.

What Did Harry Truman Say at the Charter Signing?

As the signing ceremonies concluded in the Veterans Auditorium, President Harry S. Truman addressed representatives from 50 nations, urging them to lead responsibility toward lasting peace. His words centered on one core message: you must transform action from written ideals into reality.

Truman emphasized four critical obligations:

1. Duty – Every nation must implement the Charter's principles faithfully
2. Hope – The fallen and future generations depend on your decisive action
3. Justice – Strong nations must lead without seeking special privileges
4. Legacy – History would honor those who built this foundation

Truman declared the Charter "a solid structure upon which we can build a better world," reminding delegates that free people deserving decent lives depended entirely on their commitment to honoring it. Just as modern legislation such as Canada's Genetic Non-Discrimination Act sought to protect individuals from misuse of personal information, the Charter similarly aimed to shield people from the abuse of power on a global scale. The Charter itself came into force on October 24, 1945, marking the official birth of an organization rooted in faith in human values and universal morality rather than power or privilege. By 2025, eighty years after its adoption, 193 countries had signed the Charter and joined the United Nations, cementing its standing as the largest international organization in world history.

From Signing to Law: How the Charter Entered Force October 24

Signing the Charter on June 26, 1945, was only the first step — turning it into binding international law required nations to formally ratify it.

The ratification mechanics demanded that all five permanent Security Council members — the United States, China, France, the Soviet Union, and the United Kingdom — plus a majority of other signatory states deposit their ratifications.

The entry timeline moved quickly: the U.S. Senate ratified the Charter by an 89–2 vote on July 28, 1945.

By October 24, 1945, sufficient nations had completed their deposits, officially bringing the Charter into force and founding the United Nations.

That four-month interval between signing and legal force mattered enormously — you'd be watching a document transform from a promise into binding international law. The Charter has since been amended three times, in 1963, 1965, and 1973, reflecting the evolving needs of its growing membership.

The document that entered force was no ordinary treaty — Charter obligations supersede all other treaty commitments member states hold, making it the supreme instrument of international law among its signatories. Just as the Historic Sites Act of 1935 declared preservation an official government responsibility for the first time in U.S. law, the UN Charter similarly marked a turning point by codifying international cooperation as a binding legal framework rather than a voluntary aspiration.

How China Became a Permanent UN Security Council Member

China's path to permanent Security Council membership began with its recognized role as a victorious Allied power in World War II — specifically its grueling fight against Japan in the Second Sino-Japanese War.

President Roosevelt championed China's inclusion among the Big Five, and the Chinese delegation signed the Charter on June 26, 1945.

Key milestones in China's Security Council history:

1. 1945 — ROC joins as founding permanent member
2. 1949 — PRC legitimacy established after winning the Civil War
3. 1971 — Resolution 2758 transfers the seat to the PRC
4. Present — China exercises security vetoes, often alongside Russia, shaping global outcomes

You're witnessing how one signature launched decades of expanding Chinese influence. As a permanent member, China holds veto power over any substantive Security Council resolution, enabling it to block decisions it opposes. Much like Canada's recent updates to the Investment Canada Act strengthened oversight of foreign influence, the UN Charter established binding frameworks to govern how powerful nations engage with the international community.

The Soviet Union's decision to boycott the UN from January to August 1950 was a direct attempt to pressure the organization into granting PRC representation over the ROC.

How the U.S. Senate's 89-2 Vote Ratified the UN Charter

The U.S. Senate's 89-2 vote on July 28, 1945, ratified the UN Charter, marking a decisive shift away from American isolationism. Senate procedure moved swiftly, with the Foreign Relations Committee approving the charter before the full chamber voted. Ratification debates produced overwhelming bipartisan support, reflecting broad recognition of America's postwar responsibilities.

Only two senators dissented. Hiram Johnson of California cast his opposing vote from the Senate barbershop, reclining with a hot towel on his face. Light rain fell over Washington as the proceedings concluded. Similar dramatic resignations over matters of principle, such as Michael Chong's resignation as Intergovernmental Affairs Minister over ethnic versus civic nationalism concerns, demonstrate how deeply symbolic votes can expose fundamental fault lines within a government.

You can see why this vote mattered — the U.S. was the first permanent Security Council member to ratify. Without American ratification, the treaty couldn't enter force, which it officially did on October 24, 1945. Senator Thomas Connally, chair of the Senate Foreign Relations Committee, framed the vote as a rejection of American isolationism, declaring that the U.S. cannot live in a cellophane wrapper. This outcome stood in sharp contrast to the 1919 League of Nations failure, when growing isolationism and partisan politics during Woodrow Wilson's presidency prevented the U.S. from joining.

Which UN Charter Principles Still Hold 80 Years Later?

Eight decades after China and four other nations signed the UN Charter in San Francisco, its core principles haven't just survived — they've shaped the architecture of modern international relations.

You can trace today's global order directly back to four enduring pillars:

1. Peace principles prohibiting force except in self-defense (Articles 2(4) and 51)
2. Human rights protections anchored by the 1948 Universal Declaration
3. Multilateral cooperation binding 193 Member States through treaty obligations
4. Social progress commitments addressing climate change, equity, and development

Secretary-General Guterres called the Charter the "bedrock of international relations" — not optional law.

Scholars like Christian Tomuschat describe it as the "constitution of the international community."

Violations persist, but these principles remain indispensable for preventing conflict cycles worldwide. The Charter's reach has extended well beyond its original scope, having guided international action on decolonisation, human rights, and sustainable development across the decades since its ratification. This same spirit of collaborative lawmaking has influenced domestic legislation worldwide, including Canada's Bill C-92, which established a legislative framework to address Indigenous child welfare through co-developed policy with Indigenous communities.

Today, the UN serves as a platform for dialogue among almost all states worldwide, uniquely bringing together future-oriented global issues — from climate and artificial intelligence to food security and conflict reconciliation — under a single institutional roof.
