Interdependence and Sovereignty in Contemporary International Relations: Realist, Liberal, and Constructivist Perspectives

Introduction

The relationship between interdependence and sovereignty constitutes one of the most enduring debates in International Relations (IR) theory. Classical conceptions of sovereignty, rooted in the Peace of Westphalia (1648), conceive the sovereign state as possessing supreme authority within a defined territorial jurisdiction and independence from external interference. However, processes of economic globalization, technological integration, transnational governance, environmental interdependence, and global production networks have intensified interactions among states, raising fundamental questions about the continued viability of traditional sovereignty.

The concept of interdependence gained prominence through the works of scholars such as and , who argued that states increasingly operate within webs of mutual dependence that alter the dynamics of power and governance. Yet the implications of interdependence for sovereignty remain deeply contested. Realists view sovereignty as resilient despite growing interconnectedness, liberals regard interdependence as transforming rather than eliminating sovereignty, while constructivists emphasise the socially constructed and historically evolving character of sovereignty itself.

This essay critically evaluates realist, liberal, and constructivist interpretations of the relationship between interdependence and sovereignty. It argues that contemporary interdependence does not signify the disappearance of sovereignty but rather its adaptation and reconfiguration within emerging structures of global governance. Sovereignty remains a foundational organising principle of world politics, although its exercise increasingly occurs through networks, institutions, and shared regulatory frameworks that challenge purely territorial understandings of political authority.

Conceptualising Sovereignty and Interdependence

Sovereignty: Classical and Contemporary Understandings

The modern concept of sovereignty is most commonly associated with the writings of and . Sovereignty traditionally comprises two dimensions:

Dimension	Meaning
Internal Sovereignty	Supreme authority within a territory
External Sovereignty	Independence from external control and recognition by other states

Stephen Krasner famously described sovereignty as an “organised hypocrisy,” arguing that while sovereignty remains a normative principle, states have frequently violated or modified it in practice.

Interdependence in International Relations

Keohane and Nye define interdependence as situations characterised by reciprocal effects among actors in different countries. Interdependence involves:

• Economic integration.
• Financial interconnectedness.
• Technological networks.
• Environmental linkages.
• Transnational governance mechanisms.

Unlike mere interconnectedness, interdependence implies mutual sensitivity and vulnerability, making states increasingly responsive to developments beyond their borders.

I. Realist Interpretations: Sovereignty Remains Supreme

1. Interdependence as a Reflection of State Interests

Realists regard states as the primary actors in an anarchic international system. From the perspective of scholars such as , , and , sovereignty remains indispensable because survival remains the ultimate objective of states.

For realists:

• Interdependence is subordinate to power.
• States participate in cooperative arrangements only when advantageous.
• Sovereignty continues to determine political authority.

Economic interdependence may increase interactions, but it does not eliminate strategic competition.

---

2. Vulnerability and Asymmetric Interdependence

Realists emphasise that interdependence often creates vulnerabilities.

Keohane and Nye distinguished between:

• Sensitivity interdependence.
• Vulnerability interdependence.

Realists argue that powerful states exploit asymmetrical dependencies to enhance influence.

Examples include:

• Energy dependence in Europe.
• Financial sanctions imposed by major powers.
• Technological restrictions in strategic sectors.

From this perspective, interdependence frequently becomes an instrument of statecraft rather than a force diminishing sovereignty.

---

3. The Return of Geopolitics

Contemporary geopolitical developments reinforce realist arguments.

Events such as:

• US-China strategic competition.
• Russia–Ukraine conflict.
• Supply-chain securitisation.

demonstrate that states prioritise security considerations over economic efficiency when core interests are threatened.

Realists therefore conclude that sovereignty remains the fundamental organising principle of international politics despite growing interdependence.

---

II. Liberal Interpretations: Sovereignty through Cooperation

1. Complex Interdependence

The liberal perspective is most closely associated with Keohane and Nye’s theory of complex interdependence.

According to this framework:

• Multiple channels connect societies.
• Military force becomes less central in many issue areas.
• International institutions facilitate cooperation.

Interdependence generates incentives for states to coordinate policies and manage common problems collectively.

---

2. Institutionalised Sovereignty

Liberals argue that sovereignty is transformed rather than weakened.

States voluntarily delegate authority to institutions because:

• Collective action improves outcomes.
• Cooperation reduces transaction costs.
• Institutions provide predictability.

Organizations such as:

• ,
• ,
• ,

illustrate how states exercise sovereignty through institutional participation.

Delegation is viewed not as a loss of sovereignty but as a strategic exercise of sovereign choice.

---

3. Globalization and Shared Governance

Liberal theorists argue that many contemporary challenges transcend national boundaries:

• Climate change.
• Pandemics.
• Financial crises.
• Cybersecurity threats.

No state can effectively address these issues alone.

Consequently, sovereignty increasingly involves participation in governance arrangements that facilitate collective problem-solving.

Anne-Marie Slaughter’s concept of “disaggregated sovereignty” highlights how governmental agencies cooperate directly across borders while remaining embedded within sovereign states.

---

4. Sovereignty as Capacity

Liberals often distinguish between formal sovereignty and effective sovereignty.

Interdependence may actually enhance state capacity by providing access to:

• International markets.
• Technology.
• Information.
• Regulatory cooperation.

Thus, sovereignty becomes more effective through integration rather than isolation.

---

III. Constructivist Interpretations: Sovereignty as a Social Institution

1. Sovereignty as a Social Construct

Constructivist scholars such as , , and challenge the assumption that sovereignty possesses a fixed meaning.

For constructivists:

• Sovereignty is socially constructed.
• Its meaning evolves through norms and practices.
• International society continuously redefines legitimate authority.

Wendt’s famous assertion that “anarchy is what states make of it” applies equally to sovereignty.

---

2. Normative Transformation of Sovereignty

The contemporary era has witnessed the emergence of new sovereignty norms.

Examples include:

• Human rights regimes.
• Humanitarian intervention.
• Responsibility to Protect (R2P).
• International criminal accountability.

These developments indicate that sovereignty is increasingly understood not merely as control but also as responsibility.

Francis Deng’s notion of “sovereignty as responsibility” exemplifies this transformation.

---

3. Interdependence and Identity Formation

Constructivists argue that interdependence shapes identities and interests.

Participation in institutions:

• Socialises states into common norms.
• Alters preferences.
• Creates expectations of appropriate behaviour.

For example, regional integration within the has transformed traditional understandings of sovereignty without eliminating statehood.

Interdependence and the Transformation of Sovereignty

Economic Sovereignty

Global production networks and financial integration constrain autonomous economic policymaking.

However:

• States continue to regulate markets.
• Governments shape industrial strategies.
• Economic nationalism has re-emerged.

Rather than disappearing, economic sovereignty has become more complex and negotiated.

---

Technological Sovereignty

The digital age illustrates sovereignty’s adaptation.

States increasingly seek:

• Data sovereignty.
• Cyber sovereignty.
• Technological autonomy.

Far from declining, sovereignty is being reasserted in new domains.

---

Environmental Sovereignty

Climate governance demonstrates how sovereignty adapts through collective commitments.

Agreements such as the involve voluntary obligations accepted by sovereign states.

These arrangements modify the exercise of sovereignty without abolishing it.

---

Does Interdependence Mean the Decline of Sovereignty?

Arguments Supporting Decline

Some scholars contend that:

• Multinational corporations constrain governments.
• Global finance limits policy autonomy.
• International institutions influence domestic legislation.
• Transnational problems transcend territorial control.

These developments appear to weaken traditional notions of absolute sovereignty.

---

Arguments Supporting Adaptation

However, empirical evidence suggests adaptation rather than disappearance.

States remain:

• Primary legal actors.
• Creators of international institutions.
• Controllers of citizenship and territory.
• Principal providers of security.

Even highly integrated arrangements depend upon state consent.

As Krasner observes, sovereignty has historically evolved in response to changing political and economic circumstances.

---

Conclusion

The relationship between interdependence and sovereignty is best understood not as a zero-sum conflict but as a dynamic process of institutional adaptation. Realists correctly emphasise the enduring significance of state power and strategic autonomy, demonstrating that interdependence often generates new vulnerabilities and opportunities for coercion. Liberals highlight the ways in which states employ institutions and cooperation to manage mutual dependence and enhance governance capacity. Constructivists provide a deeper understanding of how the very meaning of sovereignty evolves through changing norms, identities, and practices.

Contemporary interdependence has undoubtedly challenged traditional Westphalian notions of exclusive territorial authority. Yet it has not rendered sovereignty obsolete. Instead, sovereignty has been reconfigured through shared governance, institutional participation, transnational regulation, and emerging normative frameworks. The contemporary international system therefore reflects neither the decline nor the disappearance of sovereignty, but its transformation into a more complex and multidimensional institution capable of operating within an increasingly interconnected world.
