What must I know about the US–China comparison?
What does existential mean in this question?
An existential threat endangers a country’s survival or its way of life. The exam question uses this word for China. This card sets out the yardsticks for the comparison.
What did the exam ask?
UPSC CSM 2021, GS Paper II, Q10 quoted a claim. It said the USA faces an existential threat in a China that is much more challenging than the erstwhile Soviet Union. Candidates had to explain it.
Which five yardsticks help?
- Economy. How big is each rival, and how closed or open?
- Trade ties. How much does the USA buy from and sell to each rival?
- Technology. Who controls the key tools of the age?
- Military power. Warheads and defence spending.
- Alliances. Who stands with each rival?
Why is the Cold War the test case?
The Cold War is the standard example of a long US rivalry with a great power. It ended on 25 December 1991. On that day the Soviet flag came down over the Kremlin for the last time.

How big is China's economy?
This card shows how large China’s economy is. It uses the World Bank series, updated on 8 October 2026.
What does GDP in dollars say?
The World Bank series gives China’s GDP at $18.27 trillion in 2023. It was $18.73 trillion in 2024. It reached $19.50 trillion in 2025.
The US figure for 2025 is $30.77 trillion. China’s 2025 GDP is therefore about 63% of the US figure.
Does purchasing power change the picture?
PPP adjusts GDP for local prices. In the World Bank PPP series China’s GDP was $17.75 trillion in 2014. The US figure was $17.61 trillion. So China passed the USA in PPP terms in 2014 in this series.
By 2025 the PPP gap was wide. China stood at $41.26 trillion and the USA at $30.77 trillion. Some older notes give 2016–17 as the crossing year. This series shows 2014.
What do we know about the Soviet economy?
In 1989 the Bush administration hoped the Soviet Union would move to a market oriented economy. That tells us the economy was not market oriented then. The History Office page gives no GDP comparison, so this lesson makes none.
Sources: World Bank GDP series, updated 8 October 2026, World Bank PPP series for China and the USA. Also: Historian page on the 1989 policy review.
How tied together are the two economies?
The USA and China trade in very large amounts. This card shows the US Census goods figures.
How much goods trade is there?
The Census Bureau counts goods only. US goods exports to China were $154.0 billion in 2022. Imports were $536.3 billion. Total trade was about $690.3 billion.
Total goods trade was about $574.9 billion in 2023. It was about $583.6 billion in 2024. It fell to about $414.6 billion in 2025.
Is the gap shrinking?
The US goods deficit with China was $382.3 billion in 2022. It was $202.7 billion in 2025. Exports fell to $106.0 billion in 2025, and imports fell to $308.7 billion.
Who is the biggest partner?
In December 2023 Census data China ranked third among US trading partners. Mexico was first at $798.8 billion. Canada was second at $774.3 billion. China stood at $575.0 billion.
Mexico also sold more goods to the USA than China did in 2023. Mexico’s figure was $475.6 billion and China’s was $427.2 billion.

Who leads in chips and technology?
Today a key race is about chips and computing. This card shows two US moves from 2022.
What did the CHIPS law do?
The US Congress passed the law that carries the CHIPS Act. It was approved on 9 August 2022. Its section 102 set up the CHIPS for America Fund in the US Treasury.
What did the October 2022 export rule do?
The Bureau of Industry and Security issued a rule on 7 October 2022. The Federal Register published it on 13 October. It put controls on advanced computing chips and some chipmaking items.
The rule also told US persons that some work in China needs a licence. That work is support for the development or production of certain chips. The rule also widened controls on 28 Chinese entities.
Why does it matter for the comparison?
The rule names computing chips and chipmaking items. A fight over these items reaches into the economy itself. That is one reason analysts call this rivalry different in kind.
Sources: Federal Register, BIS rule of October 2022, US Public Law 117-167, approved 9 August 2022.
What is good to know about arms, allies and strategy?
How do the militaries compare?
Military power is where the Soviet Union looks strongest. This card gives the latest nuclear and spending numbers.
What do the nuclear numbers say?
The SIPRI Yearbook came out on 8 June 2026. It estimates 12,187 warheads worldwide in January 2026. About 9,745 sit in military stockpiles. About 4,012 are deployed with missiles and aircraft.
SIPRI puts China at around 620 warheads. Russia and the USA together hold about 83% of stockpiled warheads.
The Federation of American Scientists says the world total peaked near 70,300 in 1986. The Cold War peak was far above today’s total.
What do the spending numbers say?
SIPRI’s data of 27 April 2026 puts world military spending at $2,887 billion in 2025. The USA spent $954 billion. China spent $336 billion, up 7.4%, the 31st rise in a row. Russia spent $190 billion.
China’s spending is about a third of the US figure.
What does China’s own budget say?
China proposed a 2026 defence budget of 1.91 trillion yuan, about $276.9 billion. That is up 7%. The 2025 budget was 1.78 trillion yuan, up 7.2%.
Sources: SIPRI Yearbook 2026 press release, 8 June 2026, Federation of American Scientists, world nuclear forces. Also: SIPRI military expenditure release, 27 April 2026, China Daily, defence budget report of March 2026.
Who had allies?
The Cold War was a contest between two blocs. This card sets the bloc dates beside the Russia–China partnership of 2022.
When were the two blocs formed?
NATO began with the Washington Treaty, signed on 4 April 1949. The Warsaw Pact followed on 14 May 1955. The Soviet Union formed it as a counterweight to NATO.
What did Russia and China say in 2022?
Russia and China issued a joint statement on 4 February 2022. It said their friendship has no limits. It said there are no forbidden areas of cooperation. It called their ties superior to the political and military alliances of the Cold War era.
So the partnership is not a treaty bloc. It is a close alignment with no formal pact.

What ended the Soviet challenge?
The Soviet challenge ended in 1991. This card follows the steps from the Office of the Historian page.
What changed from 1989?
President George H.W. Bush took office in January 1989. He ordered a review of policy on the Soviet Union. He encouraged Gorbachev’s reforms.
Gorbachev allowed elections with several parties and created a presidency. The page says this slow democratisation eventually destabilised Communist control. It also says it contributed to the collapse.
How did the end come?
After an August 1991 coup attempt, Ukraine and Belarus declared independence. Leaders of Ukraine and Belarus then met in Brest. They formed the Commonwealth of Independent States.
On 25 December 1991 Gorbachev resigned and the Soviet flag was lowered.
Why did the arsenal worry the USA?
The page calls the Soviet nuclear arsenal vast. US officials put the prevention of nuclear catastrophe first. They also wanted the arsenal secured as the union broke up.
How has US thinking about China changed?
US strategy moved from engagement to open competition. This card shows three steps with dates.
What did the 2017 strategy say?
The National Security Strategy of December 2017 named three sets of challengers. One set was the revisionist powers of China and Russia. It said China and Russia challenge American power, influence and interests.
What happened to trade?
A Federal Register notice of 20 June 2018 set an extra 25% duty on products from China. The notice also sought comment on further action.
What happened in 2025?
On 30 October 2025 the Trump–Xi meeting in South Korea ended with a truce. Al Jazeera reported that China would defer planned rare earth export controls. The USA would drop a threatened 100% tariff.
The USA would also cut a 20% fentanyl-related tariff to 10%.

What is great to know for a balanced verdict?
Which rival is stronger where?
A good answer weighs both sides. This card pulls the earlier facts into one comparison.
Where was the Soviet Union stronger?
- Weapons. The world total peaked near 70,300 warheads in 1986. China has around 620.
- Bloc. The Soviet Union led the Warsaw Pact. Russia and China have no treaty bloc.
Where is China stronger?
- Economy. China’s PPP GDP is above the US figure. It has been since 2014 in the World Bank series.
- Trade. China was the third-largest US goods trading partner in 2023.
- Technology. The US export rule of 2022 aims at chips that China wants.
What should the verdict say?
The threat differs in kind, not only in degree. The Soviet challenge was military and ideological. The Chinese challenge runs through trade, chips and economic weight.
Examiners reward balance over slogans. State both sides and then give a clear verdict.

What are the exam traps? Exam practice
What did exams ask, and what are the traps?
Exams ask for a balanced comparison. This card shows the past question and the traps.
What did UPSC CSM 2021 ask?
UPSC CSM 2021, GS Paper II, Q10 (10 marks, 150 words). The wording is as shown on this site’s UPSC CSM 2021 GS Paper II page.
“The USA is facing an existential threat in the form of a China, that is much more challenging than the erstwhile Soviet Union.” Explain.
Begin by defining the word existential. Compare the two rivals on economy, trade, technology, military power and alliances. End with a balanced verdict.
What are the traps?
- PPP year. The World Bank series shows China passing the USA in 2014. Some notes say 2016–17.
- Warhead totals. SIPRI says 12,187 for January 2026. The FAS figure for the start of 2026 is 12,321. They count differently.
- Defence spending. China’s own 2026 budget is about $276.9 billion. SIPRI’s 2025 estimate is $336 billion.
- Trade. Census figures are goods only. The 2022 total was about $690.3 billion.
- Bloc dates. NATO is 1949. The Warsaw Pact is 1955.

Questions to think through
Why does trade make this rivalry different?
Each side buys a lot from the other. Cutting those ties would hurt both, so both think twice.
Why do warhead numbers not settle the question?
Existential means survival and way of life. Missiles matter, but so do the economy, trade and chips.
Why do two sources give different defence figures?
They cover different years and use different methods. SIPRI estimates for 2025. China’s budget is a plan for 2026.
Why did the Soviet challenge end without a war between the blocs?
The Historian page describes political change. It lists elections, a coup attempt, independence moves and a resignation.
