Geopolitical Fragmentation of Global Competition Regimes

Introduction

Geopolitical fragmentation of global competition regimes refers to the increasing divergence of competition/antitrust laws, enforcement priorities, institutional approaches, and remedies across major jurisdictions because of geopolitical rivalry, economic nationalism, technological competition, national-security concerns, and competing regulatory philosophies.

Historically, competition law was principally concerned with consumer welfare, market power, efficiency, prices, output, and competitive process. Globalisation encouraged convergence around broadly similar principles. However, the digital economy, strategic technologies, supply-chain vulnerabilities, foreign subsidies, data control, artificial intelligence, semiconductors, and geopolitical rivalry have increasingly caused jurisdictions to treat competition policy as an instrument of economic security and strategic autonomy.

The result is not simply different competition laws. It is a fragmented system in which the same transaction or conduct may be:

• approved in one jurisdiction;
• prohibited or subjected to structural remedies in another;
• examined under national-security legislation elsewhere;
• tolerated because of industrial-policy considerations in another country; and
• simultaneously regulated under digital-market, data-protection, foreign-subsidy, or investment-screening regimes.

1. Meaning of Geopolitical Fragmentation

Geopolitical fragmentation occurs when competition regimes increasingly reflect national or regional strategic interests rather than a common global conception of competition.

It has several dimensions:

A. Jurisdictional fragmentation

The EU, US, UK, China, India, Japan and other jurisdictions may apply different standards to the same conduct.

B. Substantive fragmentation

Different jurisdictions may disagree about:

• relevant market definition;
• dominance;
• abuse of dominance;
• merger effects;
• consumer welfare;
• innovation competition;
• data-related market power;
• ecosystem power;
• essential facilities;
• national champions.

C. Institutional fragmentation

Different regulators may exercise overlapping authority:

• competition authorities;
• sector regulators;
• digital-market regulators;
• national-security authorities;
• foreign-investment screening bodies;
• export-control authorities;
• data-protection regulators.

D. Remedial fragmentation

A transaction may face:

• behavioural commitments in one jurisdiction;
• divestiture in another;
• prohibition elsewhere;
• licensing obligations in another;
• interoperability requirements;
• data-access obligations; or
• national-security restrictions.

2. Why Global Competition Law Is Fragmenting

2.1 Economic nationalism

Governments increasingly seek to protect strategically important industries such as:

• semiconductors;
• AI;
• cloud computing;
• telecommunications;
• defence technology;
• batteries;
• critical minerals;
• biotechnology; and
• energy infrastructure.

Competition policy can therefore become intertwined with industrial policy.

A merger that improves efficiency may nevertheless be viewed as dangerous if it creates excessive dependence on a foreign supplier.

2.2 US–China technological rivalry

Competition regulation increasingly intersects with geopolitical competition between the United States and China.

Issues include:

• semiconductor supply chains;
• AI chips;
• cloud infrastructure;
• telecommunications;
• 5G;
• critical software;
• data;
• technology exports;
• investment screening.

This creates an environment in which market competition and national security can no longer be completely separated.

2.3 European strategic autonomy

The European Union has increasingly supplemented traditional competition law with instruments addressing:

• digital gatekeepers;
• foreign subsidies;
• strategic dependencies;
• economic security;
• digital sovereignty;
• data governance.

Consequently, EU enforcement may pursue objectives extending beyond conventional price-based consumer welfare.

3. Fragmentation of Merger Control

Merger control provides perhaps the clearest example.

A multinational merger may be reviewed independently by:

• European Commission;
• US Department of Justice or FTC;
• UK CMA;
• Chinese SAMR;
• Indian CCI;
• Japanese JFTC;
• other national authorities.

These regulators do not necessarily reach the same conclusions.

Possible consequences

A transaction can therefore become subject to:

One global transaction + multiple regulatory outcomes.

For example:

EU: divestiture
US: litigation/prohibition
UK: prohibition
China: conditional approval
India: approval with behavioural remedies

This creates significant uncertainty for multinational businesses.

4. National Security and Competition Law

One of the most important developments is the increasing overlap between competition policy and national security.

Traditional competition analysis asks:

Will the transaction substantially lessen competition?

Geopolitical regulation increasingly asks:

Will the transaction create strategic dependence or compromise national economic security?

The second question may concern:

• military supply chains;
• critical infrastructure;
• sensitive data;
• semiconductor technology;
• AI capabilities;
• telecommunications;
• energy security.

This creates a potentially significant departure from purely economic competition analysis.

5. Digital Markets as a Source of Fragmentation

Digital markets intensify fragmentation because different jurisdictions conceptualise platform power differently.

A platform can simultaneously be viewed as:

• a dominant undertaking;
• a digital gatekeeper;
• an essential facility;
• a strategic infrastructure provider;
• a data intermediary;
• a national-security concern.

The EU's ex ante digital regulation, US antitrust litigation, UK digital-markets regime and China's platform regulation therefore represent different regulatory philosophies toward similar economic phenomena.

6. Six Major Case Laws

Case 1: United States v. Microsoft Corp. (2001)

Facts

Microsoft was accused of abusing its dominant position in operating systems by restricting competition from competing browsers and engaging in exclusionary practices.

Significance

The case demonstrated the willingness of US antitrust law to address technological platform power.

Relevance to geopolitical fragmentation

Microsoft illustrates an important historical foundation for modern digital competition enforcement.

The case demonstrates that:

• technological ecosystems can create durable market power;
• control of an important platform can facilitate exclusion;
• competition law can intervene in rapidly evolving technological markets.

Today, similar issues arise internationally, but different jurisdictions increasingly employ different regulatory tools.

Principle

Platform control can become a competition problem when technological dominance is used to exclude competitive threats.

7. Case 2: United States v. Google LLC – Search and Search Advertising (2024)

Facts

The US Department of Justice challenged Google's conduct concerning distribution agreements and default arrangements that allegedly reinforced Google's dominance in general search.

Significance

The litigation represents modern US antitrust scrutiny of digital ecosystems.

Relevance

The case demonstrates the US preference for traditional antitrust litigation applied to modern digital markets.

This contrasts with the EU's increasingly ex ante approach toward designated digital gatekeepers.

Geopolitical significance

A major global technology company may therefore face:

• US litigation;
• EU ex ante regulation;
• UK digital-market regulation;
• Chinese platform regulation;
• competition scrutiny elsewhere.

The same global ecosystem can consequently be subject to substantially different legal theories.

Principle

Digital distribution arrangements may reinforce market power even where services are nominally provided to consumers at zero monetary prices.

8. Case 3: Google Shopping – European Commission / General Court

Facts

The European Commission found that Google had abused its dominant position by favouring its own comparison-shopping service in search results.

The General Court substantially upheld the Commission's decision.

Significance

The case became one of the most important European decisions concerning self-preferencing and digital-platform power.

Geopolitical relevance

The European approach differs significantly from the traditional US model because the EU has increasingly treated platform architecture, preferential treatment and ecosystem control as competition concerns.

The case demonstrates how:

EU competition law can pursue competitive neutrality within digital ecosystems even where the precise harm is not simply higher consumer prices.

Principle

Dominant digital platforms cannot necessarily use their control over an important intermediary infrastructure to systematically disadvantage competing services.

9. Case 4: Intel v European Commission

Facts

Intel was found by the European Commission to have abused its dominant position through rebates provided to major computer manufacturers and distributors.

The case ultimately reached the Court of Justice.

Significance

The Court emphasised the importance of examining whether allegedly exclusionary rebates are capable of restricting competition rather than relying exclusively upon formal classifications.

Geopolitical significance

Intel demonstrates how competition enforcement concerning major technology companies can have consequences extending across global markets.

Semiconductor and processor markets are strategically important because they underpin:

• computers;
• cloud infrastructure;
• AI;
• defence systems;
• telecommunications.

Consequently, competition regulation in semiconductor-related markets increasingly intersects with industrial and geopolitical policy.

Principle

The legal assessment of exclusionary rebates must consider their actual or potential ability to foreclose equally efficient competitors.

10. Case 5: Illumina/GRAIL

Facts

The European Commission examined Illumina's acquisition of GRAIL, a company developing early cancer-detection tests.

The Commission ultimately prohibited the transaction.

Significance

The transaction became highly significant because it involved a vertically integrated acquisition involving a developing technology.

Geopolitical relevance

The case demonstrates how competition authorities increasingly examine:

• innovation;
• future competition;
• technological ecosystems;
• emerging markets;
• strategic biotechnology.

It also illustrates the growing willingness of regulators to scrutinise transactions involving nascent competition, even where conventional market shares may not adequately capture future competitive significance.

Principle

Competition law may protect innovation competition, not merely existing price competition.

11. Case 6: Qualcomm v European Commission

Facts

The European Commission imposed a major fine on Qualcomm concerning payments to Apple that were considered exclusionary.

The General Court later annulled the Commission's decision because of deficiencies in the Commission's analysis.

Significance

The case demonstrates the complexity of applying competition law to technologically sophisticated markets.

Geopolitical significance

The semiconductor and telecommunications sectors are deeply interconnected with:

• 5G;
• mobile devices;
• AI;
• national technological capabilities;
• strategic supply chains.

Competition decisions affecting major technology firms can therefore have consequences beyond conventional market competition.

Principle

Competition enforcement must remain economically rigorous even when dealing with strategically important technology markets.

12. Case 7: Qualcomm v Apple – Global Regulatory Dimension

Qualcomm's disputes with Apple also illustrate fragmentation because competition and licensing disputes involving the same companies have generated regulatory and litigation proceedings across multiple jurisdictions.

The underlying issues included:

• standard-essential patents;
• licensing;
• royalties;
• chipset supply;
• bargaining power;
• technology ecosystems.

Importance

This illustrates how a single technological relationship can simultaneously generate:

• competition-law disputes;
• intellectual-property disputes;
• contractual litigation;
• regulatory proceedings.

Different jurisdictions may adopt different approaches to the relationship between IP rights and competition law.

13. Case 8: CAT v Google / UK Competition Approach

The UK's post-Brexit competition framework increasingly operates independently from EU competition enforcement.

Digital-platform cases involving Google and other major technology firms illustrate how UK regulators may develop their own theories concerning:

• digital advertising;
• search;
• data;
• platform access;
• self-preferencing;
• interoperability.

Geopolitical significance

Brexit itself created a new layer of competition-law fragmentation.

A company operating in Europe may now face:

EU competition law + UK competition law

rather than a single European enforcement system.

Thus, geopolitical and constitutional changes can directly produce competition-regulatory fragmentation.

14. Types of Geopolitical Fragmentation

15. Competition Law and Industrial Policy

One of the greatest sources of fragmentation is the tension between:

Competition policy

Seeking:

• lower prices;
• consumer choice;
• innovation;
• efficient allocation;
• competitive markets.

Industrial policy

Seeking:

• national champions;
• strategic autonomy;
• domestic production;
• supply-chain resilience;
• technological leadership.

These objectives can conflict.

For example, protecting a domestic semiconductor producer from foreign acquisition might preserve national technological capacity but potentially reduce competition.

16. Foreign Subsidies and Competitive Neutrality

Another major development is the increasing scrutiny of foreign state subsidies.

A company may appear highly competitive because it receives:

• government financing;
• tax advantages;
• preferential loans;
• subsidised infrastructure;
• state procurement;
• government guarantees.

Competition regulators increasingly ask whether such advantages distort competition.

This creates a new form of geopolitical competition:

State-supported firms competing against privately financed firms.

The EU's foreign-subsidy framework is particularly significant in this respect.

17. Digital Sovereignty

Digital sovereignty is becoming an important component of competition policy.

States increasingly want control over:

• cloud infrastructure;
• data;
• AI models;
• semiconductor supply;
• digital identity;
• telecommunications;
• critical software.

This can produce tension with traditional competition principles.

For example, mandatory localisation of infrastructure might protect national resilience but simultaneously reduce:

• cross-border competition;
• economies of scale;
• market entry;
• interoperability.

18. Data as a Strategic Competitive Asset

Data increasingly functions as an economic and geopolitical resource.

Large platforms may control:

• consumer data;
• behavioural information;
• location data;
• financial information;
• industrial data;
• training data.

This produces competition concerns involving:

Data accumulation

A dominant platform can acquire large datasets through multiple services.

Data advantage

Large datasets may improve algorithms and AI models.

Data foreclosure

Competitors may be unable to obtain comparable data.

Data portability

Users may face switching barriers.

Data localisation

States may restrict cross-border data movement.

Thus, privacy and competition law increasingly overlap with geopolitical regulation.

19. AI and Geopolitical Competition

Artificial intelligence dramatically increases fragmentation.

AI requires:

• advanced chips;
• enormous computing capacity;
• cloud infrastructure;
• datasets;
• engineering talent;
• model-development ecosystems.

Countries therefore increasingly regard AI infrastructure as strategically important.

Competition policy consequently faces questions such as:

• Can cloud providers discriminate against AI startups?
• Can dominant chip manufacturers restrict access?
• Can foundation-model providers lock users into ecosystems?
• Can governments subsidise domestic AI champions?
• Can export controls alter competitive conditions?
• Can compute concentration create an essential-facility problem?

This produces a new relationship:

Compute power → AI capability → economic power → geopolitical power.

20. Extraterritorial Competition Enforcement

Competition law has become increasingly extraterritorial.

A transaction or conduct occurring outside a country can be investigated if it substantially affects that country's market.

This produces overlapping jurisdiction.

For example:

US authority
↓
investigates global technology company

EU authority
↓
investigates same conduct

UK authority
↓
separate investigation

China/India/Japan
↓
additional proceedings

The company must therefore comply with multiple legal systems simultaneously.

21. Conflicting Remedies

Fragmentation becomes particularly problematic when remedies conflict.

Suppose one authority orders:

Divestiture of Business A.

Another authority requires:

Integration of Business A to preserve interoperability.

A third authority requires:

Domestic ownership of Business A.

The company may be unable to satisfy all three requirements efficiently.

This produces a phenomenon sometimes described as remedial fragmentation.

22. Forum Shopping

Geopolitical fragmentation can encourage strategic behaviour.

Companies may attempt to:

• structure transactions to avoid particular jurisdictions;
• locate assets in favourable jurisdictions;
• choose contractual governing law strategically;
• seek regulatory approvals in particular countries first;
• restructure global supply chains.

Regulators may also compete for jurisdictional influence.

23. Risk of Regulatory Protectionism

A major danger is that competition law could become a vehicle for disguised protectionism.

For example:

"Competition protection" may actually protect a domestic incumbent.

The distinction between legitimate competition enforcement and industrial protectionism therefore becomes increasingly important.

Competition authorities must demonstrate that intervention is based on competitive harm, rather than nationality alone.

24. Impact on Multinational Enterprises

Businesses operating globally face:

Higher compliance costs

Multiple regimes require separate:

• filings;
• economic studies;
• legal opinions;
• behavioural commitments.

Longer transaction timelines

Global mergers may require sequential or parallel approvals.

Strategic uncertainty

A transaction considered economically rational may become impossible because of conflicting regulatory requirements.

Supply-chain restructuring

Companies may establish geographically separate production and technology systems.

Increased regulatory risk

Digital and technology firms may face continuous supervision rather than one-time merger review.

25. Impact on Developing Countries

Geopolitical fragmentation creates both opportunities and risks for developing economies.

Opportunities

Developing countries can:

• strengthen domestic digital industries;
• negotiate technology-transfer arrangements;
• protect strategic infrastructure;
• develop independent competition institutions.

Risks

However, excessive fragmentation can:

• increase technology costs;
• reduce foreign investment;
• create regulatory burdens;
• encourage protectionism;
• fragment digital markets;
• prevent economies of scale.

For countries such as India, the central challenge is to balance:

strategic autonomy + open competition + consumer welfare + innovation.

26. Relationship Between Competition Law and Economic Security

The modern competition regime is increasingly moving from:

Competition → Consumer Welfare

toward a broader framework:

Competition + Innovation + Resilience + Economic Security + Strategic Autonomy

This does not mean that traditional competition principles disappear.

Instead, competition law increasingly operates within a wider regulatory architecture.

27. Core Legal Problems Created by Fragmentation

27.1 Conflicting jurisdiction

Which regulator should decide?

27.2 Conflicting substantive standards

What constitutes abuse or competitive harm?

27.3 Conflicting remedies

Which remedy should prevail?

27.4 National champions

Should strategically important domestic companies receive special protection?

27.5 Security exceptions

When can national security override competition principles?

27.6 Extraterritoriality

How far can a competition authority regulate foreign conduct?

27.7 Regulatory duplication

How should competition authorities coordinate with:

• data regulators;
• investment-screening authorities;
• telecommunications regulators;
• national-security bodies?

28. Possible Solutions

1. Greater international cooperation

Competition authorities should strengthen cooperation through:

• information sharing;
• coordinated investigations;
• merger-review cooperation;
• common analytical methodologies.

2. Clear separation of competition and protectionism

National security should not automatically become a justification for protecting inefficient domestic firms.

3. Procedural coordination

Authorities should coordinate:

• filing deadlines;
• evidence requests;
• remedies;
• commitments.

4. Common principles for digital markets

International principles could address:

• interoperability;
• self-preferencing;
• data access;
• platform neutrality;
• cloud switching;
• AI infrastructure.

5. Proportionality

Geopolitical objectives should be pursued through the least competition-restrictive means possible.

29. Overall Legal Assessment

The geopolitical fragmentation of competition regimes represents a structural transformation of international economic regulation.

The traditional assumption was:

Global markets require increasingly harmonised competition rules.

The emerging reality is:

Global markets increasingly operate within competing geopolitical regulatory blocs.

The EU increasingly emphasises digital fairness, market contestability and strategic autonomy.

The US traditionally relies more heavily upon litigation-based antitrust enforcement, although its approach to digital platforms is becoming more interventionist.

China integrates competition regulation with a broader framework of state economic governance and strategic development.

The UK is developing a distinct post-Brexit digital competition framework.

India and other emerging economies increasingly face the task of reconciling open markets with digital sovereignty and strategic autonomy.

Conclusion

Geopolitical fragmentation of global competition regimes means that competition law is no longer developing solely as a globally convergent body of economic law. It is increasingly influenced by geopolitical rivalry, industrial policy, technological sovereignty, national security, supply-chain resilience and strategic autonomy.

The cases involving Microsoft, Google, Intel, Qualcomm and Illumina/GRAIL demonstrate the evolution from traditional antitrust toward increasingly sophisticated regulation of technology, innovation and ecosystems.

The central legal challenge is to prevent geopolitical considerations from transforming competition law into economic protectionism, while still allowing governments to address genuine national-security and strategic vulnerabilities.

Ultimately, the future global competition regime is likely to be neither completely harmonised nor completely fragmented. It will probably consist of regional regulatory blocs connected through cooperation mechanisms, with increasing overlap between competition law, digital regulation, foreign-subsidy control, investment screening, data governance and economic-security policy.

Key proposition:

The principal danger of geopolitical fragmentation is not merely inconsistent competition rules; it is the transformation of competition policy from a primarily market-oriented discipline into a strategic instrument of geopolitical economic governance.
