How dependent is Britain on China and what risks does it pose to business and security?

Britain’s economic relationship with China has grown deeper over the past decades, touching everything from trade and technology to critical infrastructure and research. While the benefits of this engagement are clear, the increasing reliance on Chinese investment and supply chains is raising questions about national security, corporate resilience, and the country’s ability to act independently.

A Complex Balancing Act

For years, successive British governments have sought to maintain a delicate balance: attracting Chinese investment while safeguarding national interests. Recent setbacks, including the collapse of a high-profile espionage trial, have exposed the difficulties of this approach. Legal failures, experts argue, reflect not just isolated judicial missteps, but a broader tension between political caution, economic incentives, and strategic security concerns.

China is no longer just a commercial partner; it is a state with a coordinated global strategy. Its investments are strategically placed across infrastructure, energy, technology, and academia. British universities, for example, increasingly rely on Chinese funding and tuition from students, while critical materials for manufacturing and green energy projects are often sourced from Chinese-controlled supply chains.

The implications are straightforward: when one country wields disproportionate influence over the economy, policy decisions and public discourse are inevitably affected. Over time, warning signs may be muted, and sensitive issues—such as espionage or coercion—may be downplayed to avoid economic repercussions.

Business on the Frontline

This challenge extends beyond government corridors. The private sector faces heightened exposure, as demonstrated in Heligan Group’s report, When Commerce Conquers Conservation. British companies are often unaware of how intertwined they are with China. Supply chains, data storage, and investor relationships can all introduce vulnerabilities that affect national and corporate security.

Most businesses focus on efficiency, cost, and reliability—an approach that worked during a period of globalisation perceived as low-risk. Today, this mindset leaves firms susceptible to cyberattacks, data breaches, and supply chain disruptions. Smaller suppliers, contractors, and partners have become prime targets, offering hackers indirect access to larger systems.

Companies cannot wait for government intervention. Building resilience involves asking critical questions: Can suppliers be replaced if tensions with China escalate? Do companies fully understand where their data flows and who has access? Are cybersecurity measures sufficient? Simple, proactive steps—diversifying suppliers, safeguarding sensitive data, and vetting investors—can significantly reduce exposure without requiring new legislation.

Moving Forward: Strategy Over Complacency

Experts warn that complacency poses a greater threat than confrontation. China has historically leveraged economic power to influence other nations, targeting sectors that shape the future, from energy and artificial intelligence to critical infrastructure. Britain’s instinct to prioritise short-term economic benefits over strategic independence could gradually erode its autonomy.

The solution lies in a combination of government honesty and corporate strategy. Policymakers must openly assess the country’s dependency on China, while businesses need to integrate risk awareness into strategic planning. By identifying vulnerabilities and taking measured actions, Britain can maintain global engagement without ceding control.

The goal is not to sever economic ties with China, but to ensure that British decisions are guided by national interests rather than external pressures. The responsibility for achieving this balance rests not only in Westminster but also in boardrooms across the country.
