UK faces accelerating threat from Chinese cyber espionage and covert activities

The United Kingdom is increasingly alarmed by China’s multifaceted approach to threatening national security, including cyber attacks, physical surveillance, and political influence operations, prompting a comprehensive response.

China poses a significant national security threat to the United Kingdom, encompassing direct dangers such as cyber attacks and espionage, as well as indirect threats stemming from its assertive activities in regions like the South China Sea. This perspective was recently underscored by a former Cabinet Secretary on the Crisis Room podcast, who highlighted China’s multifaceted approach to challenging UK security and interests.

The UK government has long been vigilant against Chinese cyber intrusions and covert operations. In July 2021, then-Foreign Secretary Dominic Raab publicly accused Chinese state-sponsored groups of orchestrating a large-scale cyber attack on Microsoft Exchange servers. This assault affected around 250,000 servers globally, enabling extensive espionage including theft of personal data and intellectual property. Raab characterised this as part of a “reckless but familiar pattern” of Chinese behaviour, urging Beijing to cease such systematic cyber sabotage and warning of consequences should it persist.

UK security concerns extend beyond cyber threats to include physical espionage on British soil. Reports from April 2025 revealed that Chinese intelligence operatives had placed surveillance devices in key central London locations frequented by government officials and civil servants. Popular spots such as St James’s Park and surrounding Whitehall buildings were identified as prime targets for bugging efforts, prompting advisories for officials to avoid these “hotspots.” This raised alarm about the extent of China’s intrusive intelligence-gathering activities within the UK capital.

In a broader strategic move, the UK introduced the Foreign Influence Registration Scheme in June 2025 to enhance transparency around foreign political influence operations. While China was exempt from the strictest provisions, the scheme signalled a growing official determination to confront covert attempts to manipulate the UK’s political system. Security Minister Dan Jarvis emphasised the importance of accountability and visibility as tools to detect and disrupt foreign interference, reflecting the evolving challenges posed by global powers including China.

Historical context further illuminates the UK’s ongoing struggle with Chinese cyber operations. In December 2018, the Foreign Office identified a severe campaign of cyber intrusions attributed to groups acting on behalf of the Chinese Ministry of State. This campaign targeted intellectual property and commercially sensitive data across Europe, the US, and Asia. Then-Foreign Secretary Jeremy Hunt condemned these acts as some of the most extensive against the UK and its allies, demanding that China halt such hostile activities.

The National Cyber Security Centre (NCSC) has repeatedly linked Chinese state-affiliated groups to attacks on UK political institutions in recent years. A notable instance in March 2024 involved APT31, a China-backed cyber actor accused of targeting the email accounts of MPs and peers critical of China, as well as launching an attack on the Electoral Commission. This group is known for its global reach, targeting governments and parliaments beyond the UK, including Finland and Norway, underscoring the transnational nature of Chinese cyber espionage.

Concerns over cyber and intelligence threats from China are not new. As far back as 2012, then-Foreign Secretary William Hague issued firm warnings at an international cyberspace summit, marking cyber spying—as well as internet freedom suppression—as unacceptable behaviours whether conducted by states or individuals. Hague stressed the necessity of global cooperation to establish clear norms and “rules of the road” in cyberspace, aiming to curb the rise of online crime and state-sponsored cyber aggression.

Taken together, these revelations and governmental responses paint a comprehensive picture of a persistent and evolving challenge for the UK. China’s combination of cyber intrusions, espionage through physical surveillance, and covert political influence operations places it at the centre of Britain’s national security concerns. The UK’s multifaceted response—from public accusations and defensive cyber measures to legislative schemes targeting foreign interference—reflects the complexity and urgency of managing this threat in an increasingly interconnected global environment.
