IB Global Politics Interdependence Notes

Understanding Interdependence

1. Economic Interdependence:
   1. Trade: Countries rely on each other for goods and services.
   2. Investment: Cross-border investments create financial linkages.
   3. Example: The global supply chain for electronics involves components from multiple countries.
2. Political Interdependence:
   1. Diplomacy: States collaborate on issues like climate change and security.
   2. Institutions: Organizations like the UN facilitate cooperation.
   3. Example: The Paris Climate Agreement requires collective action to address global warming.
3. Social and Cultural Interdependence:
   1. Migration: People move across borders, sharing cultures and ideas.
   2. Communication: Technology connects individuals worldwide.
   3. Example: Social media platforms enable global movements like #MeToo.

Theoretical Perspectives on Interdependence

1. Liberalism:
   1. Emphasizes the benefits of cooperation and institutions.
   2. Argues that interdependence reduces the likelihood of conflict.
2. Realism:
   1. Views interdependence with skepticism, highlighting vulnerabilities.
   2. Argues that states prioritize security and may exploit dependencies.
3. Constructivism:
   1. Focuses on how interdependence shapes identities and norms.
   2. Argues that shared values can strengthen cooperation.

Challenges and Criticisms of Interdependence

1. Vulnerability:
   1. Interdependence can create vulnerabilities, such as reliance on a single supplier for critical resources.
   2. Example: The 2021 semiconductor shortage disrupted global industries.
2. Inequality:
   1. Interdependence may exacerbate inequalities between countries, with wealthier nations benefiting more from global trade.
   2. Example: Developing countries often face barriers to accessing global markets.
3. Sovereignty:
   1. Some argue that interdependence undermines state sovereignty by limiting policy autonomy.
   2. Example: International trade agreements may constrain domestic economic policies.

The Future of Interdependence

1. Technological Advancements:
   1. Emerging technologies like artificial intelligence and blockchain may reshape interdependence by creating new forms of connectivity.
2. Geopolitical Shifts:
   1. Rising tensions between major powers, such as the US and China, may lead to a reevaluation of interdependent relationships.
3. Sustainability:
   1. The global focus on sustainability and climate change will likely increase the importance of interdependence in addressing transnational challenges.

Case study

Global Semiconductor Supply Chain and Interdependence

• Background
  • Semiconductors (microchips) are essential to every modern industry - from smartphones to military systems to medical devices.
  • The global chip market is worth over $580 billion (2023) and is projected to exceed $1 trillion by 2030.
  • Taiwan (TSMC) manufactures over 90% of the world's most advanced chips - creating an extreme concentration of strategic dependency.
• Interdependence in Action
  • The supply chain spans dozens of countries: US designs chips, Netherlands (ASML) makes lithography machines, Taiwan fabricates, China assembles.
  • The COVID-19 chip shortage (2020-2022) shut down auto factories, delayed electronics, and cost the global economy an estimated $500 billion.
  • Demonstrates how disruption in one node of an interdependent system causes cascading global effects.
• Geopolitical Tensions
  • The US imposed export controls (2022) blocking China's access to advanced chips and chip-making equipment - weaponizing interdependence.
  • China is investing $150+ billion to build domestic chip manufacturing capacity and reduce dependence on foreign technology.
  • Taiwan's role gives it a "silicon shield" - some argue global dependence on TSMC deters Chinese invasion.
• IB Connections
  • The best contemporary case for analyzing complex interdependence and its political consequences.
  • Illustrates how economic interdependence can be both a source of peace (mutual dependence) and conflict (weaponized leverage).
  • Raises questions about whether globalization is reversible or whether "decoupling" is economically feasible.

Case study

The COVID-19 Pandemic and Global Interdependence

• Background
  • COVID-19 emerged in Wuhan, China in late 2019 and within months became a global pandemic - infecting over 770 million and killing nearly 7 million by 2024.
  • The virus spread through the very networks of global interdependence - air travel, trade routes, and supply chains.
  • Exposed how deeply connected the global economy is - and how disruption in one area cascades everywhere.
• Economic Interdependence Exposed
  • Global GDP contracted by 3.1% in 2020 - the worst recession since the Great Depression.
  • Supply chain disruptions caused shortages of PPE, semiconductors, and consumer goods worldwide.
  • Vaccine nationalism - wealthy nations hoarded doses while COVAX failed to deliver equitable global distribution.
• Governance Failures
  • The WHO was criticized for delayed response and excessive deference to China in the early stages.
  • States pursued unilateral border closures and export bans, undermining multilateral cooperation.
  • The pandemic revealed the weakness of international health governance - no binding enforcement mechanisms exist.
• IB Connections
  • The most powerful recent example of complex interdependence and its vulnerabilities.
  • Illustrates the tension between national sovereignty (border closures) and global cooperation (vaccine sharing, WHO coordination).
  • Raises questions about whether interdependence makes the world more resilient or more fragile.
