The state and globalisation

Case Study

The Global Pandemic

  • The SARS-CoV-2 pandemic originated in China in late 2019 but quickly spread across the world

Timeline

  • On January 30th 2020, the World Health Organisation (WHO) declared the rapid spread of the disease a public health emergency of international concern

    • On March 11th, a global pandemic was announced

  • Vaccine research was conducted immediately

    • In December 2020 a vaccine was made available through international agencies co-led by the WHO

  • The WHO advised states to protect citizens by enforcing travel restrictions, lockdown, mandating masks and other measures

    • Misinformation quickly spread through social media

Impacts

  • Devastating global impacts included

    • Tourism collapsed 

    • Businesses were forced to close 

    • Millions of jobs were lost 

    • The global supply chain of goods and services was severely disrupted

    • Disruption of food supply systems resulted in shortages and  price increases

    • Over 7 million people died globally

Theoretical explanations

  • The global pandemic can be examined through the contrasting lenses of Realism and Liberalism

Realist perspective

Liberal perspective

  • Realists argue that interdependence made states more vulnerable during the pandemic

  • Global connections enabled the rapid spread of the disease, alongside misinformation

  • Economic interdependence led to severe economic disruption when borders closed and supply chains collapsed

  • Despite the presence of global governance institutions, states ultimately acted independently

    • For example, Sweden initially adopted limited restrictions, ignoring much of the guidance from the WHO

  • States prioritised national self-interest, particularly in access to treatment and vaccines

  • Poorer states and populations suffered higher death rates and greater economic damage, increasing global inequality

  • Liberals argue that complex interdependence enabled cooperation and an effective response

  • Multiple actors – including IGOs, NGOs and multinational corporations – coordinated containment efforts

  • This cooperation helped produce an effective vaccine within a year

  • Economic interdependence incentivised states to support a coordinated global response

  • Global governance institutions, especially the WHO, provided clear guidance during uncertainty

  • Accurate information and public health advice spread rapidly across borders

  • Many states adopted WHO-recommended measures and cooperated through initiatives such as COVAX, which aimed to ensure global vaccine access

  • State sovereignty was the main barrier to an even more effective global response

Global governance: political and economic

  • Realism and liberalism offer contrasting interpretations of global governance

    • They disagree over whether political and economic cooperation meaningfully constrains state behaviour

Political global governance

Realist view

  • Realists argue that true global governance does not exist because there is no authority above the state

    • States only participate in international institutions when it serves their national interest

    • Powerful states can ignore international rules without serious consequences

      • E.g. The USA has a low rate of acceptance of international human rights laws, supporting the realist view that states prioritise sovereignty over global rules

Liberal view

  • Liberals argue that the world is interconnected and interdependent, requiring shared rules and cooperation.

    • Global governance is seen as a rules-based international order upheld by a community of states

      • E.g. The United Nations has 193 member states, demonstrating widespread acceptance of political global governance.

Economic global governance

Realist view

  • Realists argue there is no overarching authority in global economic governance

    • International economic institutions are often viewed as tools of powerful states

    • Their interventions can cause harm by interfering in domestic economies

      • E.g. In Ghana, World Bank Structural Adjustment Programmes (SAPs) are widely criticised for increasing debt, poverty and inequality

Liberal view

  • Liberals argue that economic development and stability depend on cooperation and reduced trade barriers

    • Economic global governance is seen as essential for managing interdependence and preventing crises

      • E.g. The IMF’s bailout of Greece (2010–2018) helped prevent economic collapse and wider damage to the European economy.

Global governance: human rights and environmental

Human rights

  • Realism and liberalism offer contrasting perspectives on humanitarian intervention and the Responsibility to Protect (R2P)

    • In particular, they disagree over whether breaching state sovereignty can ever be justified to prevent severe human rights abuses

Liberal viewpoint on humanitarian intervention

Realist viewpoint on humanitarian intervention

  • It is acceptable to breach the sovereignty of a state if they not addressing, or actually causing, severe human rights abuses against their citizens

  • The threat of forcible humanitarian intervention can be enough to stop severe abuses

  • The motivations for the intervention must be carefully evaluated to ensure states are not intervening to better their own interest

  • There is a possibility that humanitarian intervention can make conflict situations worse and must be exercised with caution

  • It should be applied to any state but given the structure of the UN Security Council this is not likely

  • Forcible humanitarian intervention goes against the principles of state sovereignty by interfering in the internal affairs of another state and should not happen

  • The threat of humanitarian intervention may have no impact on whether or not human rights are abused

  • The only reason states would support humanitarian intervention is if they somehow gained from it

  • Humanitarian intervention will make conflict more complex and difficult to resolve

  • It is applied selectively by the UN’s Security Council and these powerful states and their allies are not under threat of humanitarian intervention 

Environmental issues

  • Liberalism and realism offer contrasting interpretations of environmental security

    • Liberals emphasise global cooperation and governance

    • Realists focus on state survival, competition and self-interest

Liberal viewpoint

Realist viewpoint

  • The environment is a global political challenge impacting all states and needs a supranational plan of action 

  • Environmental changes such as climate change intensifies the competition for resources which will lead to conflict

  • Global governance climate agreements and agencies are the best way to collectively address these issues as states cannot be effective in isolation

  • Realists consider environmental security an important aspect of state survival and the responsibility of the state

  • Environmental changes such as climate change intensifies the competition for resources, which will lead to conflict

  • Global governance climate agreements and agencies are designed by powerful states to protect their own interests

Power and developments

  • China’s rapid rise as a global power can be interpreted in very different ways

    • Realism and liberalism offer contrasting explanations of its development, motivations and impact on the international system

Case Study

China’s rise as a global power

  • In 1949, China experienced a communist revolution, driven by underdevelopment and social inequality

  • Western democratic states were wary of communism but did not view China as a major threat due to its limited power and influence

Integration into the global economy

  • In 2001, China joined the World Trade Organisation (WTO), marking a major shift towards global economic integration

  • Throughout the 2000s, China’s GDP grew steadily

  • Industrial output expanded rapidly, leading China to be described as the world’s factory

  • Between 2006 and 2010, China’s economic growth began to rival established global economies

Expansion of global influence

  • In 2013, China launched the Belt and Road Initiative (BRI), a large-scale infrastructure and investment project spanning Asia, Africa and Europe

  • China later became the world’s largest economy by purchasing power parity (PPP), overtaking the USA

Consolidation of power

  • In 2017, President Xi Jinping declared a New Era, emphasising innovation, global influence and national rejuvenation

  • China has increasingly asserted itself within global governance institutions, including the UN Security Council, where it holds permanent member status

Competing interpretations of China’s rise

Realist perspective

Liberal perspective

  • China’s rise is the result of deliberate state-led strategies designed to maximise power

  • Economic growth has translated into greater geopolitical power, threatening US hegemony

  • As China’s power grows, conflict with the USA is increasingly inevitable

  • Participation in institutions like the WTO and UN is a way to advance national self-interest

  • BRI and New Era suggest China aims to reshape the global power structure

  • China uses its UN Security Council position to exercise power and resist reform

  • China’s political system is effective because it delivers power and influence

  • China’s rise shows how states can develop by engaging with global governance institutions

  • Joining the WTO and global supply chains has been key to China’s economic success

  • Economic interdependence has improved living standards for millions in China

  • BRI could bring economic benefits to many developing states

  • China’s greater role in international affairs is positive for global governance

  • China’s success offers hope to less economically developed states that change is possible

  • China’s lack of democracy and limits on rights remain a major concern

Regionalism and the EU

  • The European Union (EU) embodies European regionalism yet not all European countries have joined

Case Study

Norway and the EU

  • Norway is not an EU member and it has voted against joining twice

  • Energy security and Arctic stability are issues of increasing concern to the EU, indicating the EU needs Norway, but Norway does not need the EU

  • Gas pipelines crossing the North Sea have become Europe’s lifeline since Russia’s invasion of Ukraine.

  • Norway is now the EU’s largest and most reliable  supplier of natural gas

  • It is a founding member of NATO and relies on this for security

  • It has adopted EU economic legislation from environmental standards to human rights policies 

  • Norway and the  EU are interdependent in many ways economically but it chooses to remain an independent state 

Why has Norway decided to remain outside of the EU?

Liberal interpretation of Norway’s relationship with the EU

  • Despite not joining the EU Norway is not an isolated state

    • It has many connections including free trade with this regional governance institution

  • Additionally, Norway is a founding member of NATO

    • This supports the view that states thrive with interconnectedness and globalization. 

Realist interpretation of Norway’s relationship with the EU

  • Although the EU has seen a steady increase in membership since 2000, realists argue that unless there are clear economic or security benefits, a state will not be interested in joining regional governance institutions

    • Norway is a clear illustration of this belief
