In today’s interconnected global economy, businesses expanding across borders increasingly face complex regulatory frameworks that govern foreign direct investment (FDI). Understanding and effectively navigating these restrictions have become central to international business strategy. Various jurisdictions have introduced or tightened FDI screening mechanisms to safeguard national security, critical industries, or strategic assets from perceived external threats. For multinational enterprises, private equity firms, and even sovereign wealth funds, the ability to manoeuvre through these regulatory environments is critical to securing deals and ensuring long-term growth.
Policymakers grapple with balancing open-market principles against the need to protect vital national interests. Meanwhile, investors must decipher a patchwork of legislation, administrative guidance, and political sentiment that can differ considerably across regions. A strategic approach, informed by an evolving regulatory and political context, is key to successful cross-border investments.
Understanding the Global Trend Towards Stricter FDI Review
A clear trend over the last decade is the increasing scrutiny of foreign investments by governments worldwide. Fuelled by concerns over national security, economic competitiveness, technological sovereignty, and public health, countries have expanded the range of sectors considered sensitive. Additionally, geopolitical tensions, particularly between major powers such as the United States and China, have heightened sensitivity about the origin of foreign capital.
Post-pandemic realities have amplified these concerns, with supply chain resiliency and healthcare systems gaining prominence in investment screening agendas. This shift reflects a broader rethink about economic openness and the boundaries of national security. The concept of what constitutes a national security concern is being interpreted more broadly than ever before, encompassing not only traditional defence-related sectors but also data, infrastructure, agriculture, and emerging technologies.
The complexities arising from varied and sometimes unpredictable government reactions compel investors to anticipate potential regulatory reviews early and incorporate strategies to mitigate risks throughout the transaction lifecycle.
Key Jurisdictions and Their Approaches
While numerous countries have bolstered FDI controls, the following jurisdictions offer insights into the diversity of regulatory frameworks and degrees of restrictiveness that investors must navigate. Understanding the nuanced approaches adopted by major economies is critical for structuring cross-border investment strategies.
United States: Expansive National Security Scrutiny
The Committee on Foreign Investment in the United States (CFIUS) has operated since the 1970s, but recent reforms have significantly expanded its powers. The Foreign Investment Risk Review Modernization Act (FIRRMA) of 2018 broadened CFIUS’ jurisdiction to cover non-controlling investments in sensitive sectors, particularly those involving critical technologies, infrastructure, and personal data.
The U.S. framework is risk-based rather than prescriptive; it focuses on whether a transaction could pose a threat to national security. While no blanket prohibitions exist, investors must assess early whether a filing is mandatory, voluntary, or advisable. Particularly for deals involving Chinese buyers, CFIUS scrutiny has intensified, occasionally resulting in deal prohibitions or forced divestitures.
Importantly, CFIUS operates on a case-by-case basis, retaining wide discretionary powers. Investors, therefore, must conduct thorough due diligence to predict regulatory responses. Engaging counsel experienced with CFIUS engagement strategies and mitigation measures can significantly enhance the odds of successful review outcomes.
European Union: A Patchwork with Growing Coordination
At the European level, the FDI Screening Regulation, effective from October 2020, seeks to promote cooperation and information sharing among Member States regarding foreign investments. However, the regulation does not harmonise national screening mechanisms. Each EU Member State retains autonomy over whether to establish an FDI screening regime, the sectors covered, and the procedural nuances involved.
Countries such as France, Germany, and Italy have well-established screening frameworks, particularly for critical technologies, infrastructure, healthcare, and defence-related industries. France has expanded its list of sensitive sectors and reduced the threshold for triggering investment reviews. Germany has similarly extended scrutiny to emerging technologies and critical inputs such as semiconductors and artificial intelligence.
Nonetheless, discrepancies remain across the EU. Some Member States, like Sweden and Ireland, historically had light-touch regimes, but even they have moved towards tightening controls. Companies planning cross-European investments must be prepared for multi-jurisdictional reviews and different timelines, evidentiary requirements, and political sensitivities.
United Kingdom: National Security and Investment Act
Since January 2022, the National Security and Investment Act (NSIA) governs foreign investments in the UK. The regime is among the most comprehensive globally, requiring mandatory notification and pre-clearance for acquisitions in 17 sensitive sectors, ranging from defence and energy to advanced materials and data infrastructure.
The NSIA applies not only to foreign investors but also to UK entities controlled by foreign persons. A broad definition of “control” (e.g., ownership of 25% shares or voting rights) means even minority stakes can trigger notification obligations. In addition to mandatory filing sectors, the government can call-in any transaction posing a risk to national security, including asset purchases and internal reorganisations.
The Investment Security Unit (ISU), a specialised body within the Cabinet Office, handles reviews. The ISU has demonstrated a willingness to block or impose conditions on transactions, revealing the seriousness with which the UK regards safeguarding its technological and industrial base. Investors into the UK must treat NSIA analysis as an early-stage due diligence task and factor potential regulatory scrutiny into transaction timelines.
China: Balancing Openness with Security Priorities
China officially champions openness to foreign investment but has simultaneously retained significant review mechanisms to protect national interests. The Foreign Investment Law, effective since 2020, marked a significant liberalisation, replacing earlier piecemeal regulations. Nonetheless, the national security review regime, officially regulated under the Measures for the Security Review of Foreign Investment, remains formidable.
Reviews focus primarily on military, national defence industries, critical infrastructure, and key technologies. Acquisitions of sensitive enterprises are scrutinised for impacts on national security, economic stability, and social order.
Beyond formal reviews, the reality is that strategic sectors, including advanced manufacturing, telecommunications, and data-heavy industries, may attract political attention even if not officially designated sensitive. Moreover, factors such as the investor’s home country, industry practices, and perceived geopolitical risks can inform outcomes. Therefore, while China offers immense opportunities, sophisticated navigation of formal and informal regulatory nuances is crucial for success.
Australia: A Tough Stance on National Interest Grounds
Australia’s Foreign Investment Review Board (FIRB) assesses specific types of investments to determine whether they are contrary to the national interest. Amendments implemented in 2021 under the Foreign Investment Reform (Protecting Australia’s National Security) Act expanded FIRB’s powers considerably, enabling review of investments in sensitive national security businesses, critical infrastructure, and data.
All investors, regardless of nationality, must now notify the government before undertaking investments in these sectors, even for transactions involving zero monetary value. Penalties for non-compliance are severe, including fines and unwinding of transactions.
Australia has taken a particularly stringent stance where Chinese investments are concerned, reflecting broader geopolitical shifts. Investors must allocate substantial lead time for FIRB engagement, preparing fulsome applications that demonstrate awareness of national interest considerations and, where appropriate, proposing mitigation undertakings proactively.
Japan: A Tradition of Discreet Rigour
Japan’s Foreign Exchange and Foreign Trade Act (FEFTA) provides the foundation of its FDI screening regime. Under recent reforms, investors acquiring more than 1% of shares in listed companies operating in sensitive industries such as weapons, nuclear power, telecommunications, and cybersecurity must file prior notifications.
While Japanese regulators typically conduct reviews discreetly, they possess significant authority to impose conditions or block transactions considered to undermine national security. Notably, Japan harmonises carefully with its allies, especially the United States, on aligning security priorities vis-à-vis sectors such as semiconductors and critical digital infrastructure.
Proactive engagement with regulators and careful structuring of investments—such as limiting access to classified technology and governing rights—form key risk mitigation strategies. Japan’s culture of consensus also suggests that early, constructive dialogues with target companies and industry stakeholders can smooth regulatory pathways.
Best Practices for Navigating FDI Review Challenges
Early Planning and Diligence
Identifying potential FDI regulatory hurdles should begin during the preliminary deal structuring phase. Developing a grid of relevant jurisdictions, applicable regimes, sectoral sensitivities, and trigger thresholds enables investors to anticipate potential issues timely.
Specialist advisors with deep expertise in the relevant jurisdictions should conduct a regulatory diligence parallel to standard corporate, financial, and legal investigations. Mapping out whether mandatory filings are required, the likely level of scrutiny, and estimated review timelines is crucial for accurate project planning and communication with transaction counterparts.
Strategic Engagement with Authorities
Building a credible, transparent narrative around the investment’s purpose, benefits, and compatibility with national interests can shape regulatory perceptions favourably. Proactive pre-notification consultations in several regimes allow early feedback from authorities. Even where not formally prescribed, informal outreach can detect latent concerns and allow parties to frame mitigation strategies.
Engagement should be handled with a blend of legal firmness and political sensitivity, striking a balance between asserting legal rights and accommodating legitimate regulatory concerns.
Mitigation Structures
Where potential regulatory concerns are identified, investors can proactively propose mitigation measures. These may include ring-fencing sensitive operational units, granting limited governance rights, restricting access to sensitive technology or information, and establishing separate boards for classified activities.
Regulatory authorities increasingly prefer conditioning approvals on enforceable undertakings rather than outright prohibitions. Thoughtful mitigation proposals can turn a hostile review into a negotiated resolution.
Contingency Planning
Given the uncertainties inherent in regulatory reviews, investors should structure deals to accommodate possible regulatory delays or adverse outcomes. Termination rights linked to review findings, long-stop dates, and arrangements for managing change of control or interim periods must be meticulously thought out.
Preparing communications strategies, especially for material deals attracting media or political attention, is another essential element of transaction risk management.
Future Outlook: A More Fragmented Global Investment Environment
The tightening of FDI controls shows little sign of abating. Emerging technologies such as artificial intelligence, quantum computing, and biotechnologies are likely to attract intensified scrutiny as the lines between commercial advancement and national security blur further. Public opinion, already marked by increased economic nationalism, could continue pressuring governments to impose greater oversight over foreign ownership of critical assets.
Simultaneously, regulatory cooperation among Western allies, including the EU, US, UK, Japan, Canada, and Australia, may produce greater alignment on shared security priorities. For investors, this means that multi-jurisdictional exposure could entail interconnected regulatory risks.
Conversely, global investors must also remain attuned to opportunities arising from regulatory liberalisation in certain markets keen on attracting foreign capital to stimulate post-pandemic recovery.
Ultimately, in an environment marked by change, information is power. Investors who approach FDI review frameworks not as barriers but as integral elements of deal strategy will be best positioned to thrive on the international stage. Adaptability, readiness to engage thoughtfully with regulators, and deep understanding of the shifting boundaries between commerce and geopolitics are indispensable navigational tools in the modern global investment journey.
