What this dot point is asking
Edexcel wants you to explain the characteristics and sources of superpower status, analyse how the pattern of global power has changed over time, explain the role of superpowers in the economy, governance and the environment, and evaluate the geopolitical tensions and spheres of influence this creates.
What makes a superpower
Power can be hard (coercion through force or economic pressure) or soft (attraction through culture, ideology and diplomacy); most superpowers blend both, a mix sometimes called smart power. The USA's hard power is shown by a defence budget of over \800$ billion, far larger than any rival, and its soft power by Hollywood, Silicon Valley brands and the global use of English and the dollar.
How the pattern of power has changed
China's Belt and Road Initiative, launched in 2013, has committed an estimated \1$ trillion of infrastructure investment across Asia, Africa and Europe, building ports, railways and power stations to project economic and political influence, for example the port of Gwadar in Pakistan and a controversial 99-year lease of Hambantota port in Sri Lanka after a debt default. Theories such as Modernisation theory, Dependency theory and Wallerstein's World Systems theory (core, semi-periphery, periphery) explain how this global hierarchy emerged and how power can shift between groups over time.
Superpowers in the economy, governance and environment
Superpowers dominate the global economy through TNCs, trade and currency (around 60 per cent of global foreign-exchange reserves are held in US dollars), and the governance system through institutions such as the IMF, World Bank, UN Security Council, WTO and G7/G20, often setting rules in their own interest. They also shape the environment, both as the largest emitters (China and the USA together account for over 40 per cent of global carbon dioxide emissions) and as key players in climate agreements such as the Paris Agreement, a clear synoptic link to climate change and the carbon cycle.
Geopolitical tensions and spheres of influence
The rise of emerging powers creates tensions: competition for resources and energy, trade disputes and tariffs (the US-China trade war from 2018), contested spheres of influence (the South China Sea, where China has built artificial militarised islands; Eastern Europe, where Russia's 2022 invasion of Ukraine challenged the Western order), and rivalry over technology such as semiconductors and 5G. Alliances (NATO) and blocs reshape spheres of influence, and the relative decline of established powers can heighten conflict. Synoptically, players (the USA, China, Russia, the EU) hold competing attitudes to the global order, and contested futures range from renewed US primacy to a fully multipolar or bipolar US-China world.
Examples in context
Example 1: the South China Sea. China claims most of the sea within its "nine-dash line", building and militarising artificial islands over reefs claimed by the Philippines, Vietnam and others, and ignoring a 2016 international tribunal ruling against it. The dispute shows an emerging power asserting a regional sphere of influence over strategic shipping lanes and resources, and the limits of international institutions when a superpower defies them.
Example 2: the Belt and Road Initiative in Africa. Chinese investment in railways (the Mombasa-Nairobi line in Kenya), ports and mines has built influence and infrastructure across Africa, but critics warn of "debt-trap diplomacy" where heavy borrowing leaves states dependent on China. It illustrates how a superpower uses economic hard power and investment, rather than military force, to extend its sphere of influence and challenge established Western powers.

Q1. Distinguish between hard power and soft power. [2 marks]
- Cue. Hard power coerces through force or economic pressure; soft power attracts through culture, values and diplomacy.
Q2. Explain one way superpowers maintain influence through global institutions. [4 marks]
- Cue. Dominating voting and funding in the IMF or World Bank lets them set rules and lending conditions in their own interest.

Edexcel Paper 2 (style)12 marksAssess the extent to which the global balance of power is shifting from a unipolar to a multipolar world.Show worked answer →
The post-1990 unipolar dominance of the USA is being challenged by the rise of China and other emerging powers (the BRICS), shown by China's economic scale, Belt and Road investment, military growth and assertive role in institutions. This suggests a move towards a multipolar world.
However, the USA retains huge hard and soft power: military reach, the dollar, technology, culture and alliances such as NATO. Power is multidimensional, so a country can lead economically while another leads militarily or culturally. A balanced judgement might argue the world is becoming more multipolar economically but remains closer to unipolar in military and cultural terms, with the trajectory contested. The strongest answer distinguishes dimensions of power and uses evidence to support a judgement. AO1 supplies the dimensions of power; AO2 weighs the unipolar and multipolar evidence across those dimensions to reach a judgement.
Edexcel 20188 marksExplain how superpowers use their influence over international decision-making and global institutions.Show worked answer →
This is led by AO1 with AO2 development. Explain that superpowers dominate global governance institutions: the USA and EU hold the largest voting shares in the IMF and World Bank (weighted by financial contribution), so they shape lending conditions; the five permanent UN Security Council members (USA, China, Russia, UK, France) wield a veto over resolutions; and superpowers steer the WTO and G7/G20 agendas.
Develop the analysis: this lets them set rules in their own interest (the "Washington Consensus" of free-market conditions on loans) and project soft power. Balance with the rise of alternatives such as China's Asian Infrastructure Investment Bank and the BRICS New Development Bank, which challenge that dominance. Reward specific institutions and a sense of how influence is exercised, not just listed.
