The United Kingdom has played a consequential role in enabling the advancement of China’s military and technological capabilities—particularly in the domains of artificial intelligence and semiconductor engineering—by permitting or insufficiently scrutinising the acquisition of key British chip-making and technology firms by Chinese-linked entities. Notable acquisitions include Newport Wafer Fab (NWF), Future Technology Devices International (FTDI), and Imagination Technologies, long regarded as among the most significant assets in the UK’s high-technology landscape.
In contrast to the United States—which intervened decisively to prevent Chinese attempts to obtain sensitive semiconductor technologies, including those developed by Nvidia—the British government maintained an open investment posture. This occurred despite the clear awareness within Whitehall and the UK intelligence community that Chinese state-linked actors sought these technologies for dual-use, including military, applications. China’s rapid acceleration in 5G and artificial-intelligence capabilities, which surprised policymakers in Washington, is widely understood to have been facilitated in part by such access.
Although the UK ultimately intervened in the cases of NWF and FTDI, these actions occurred only after a delay of approximately three years. By that time, it is highly probable that the relevant technological expertise and intellectual property had already been transferred abroad.
Historical Context: British Power Balancing After 1945
This pattern, however, is not without precedent. Since the end of the Second World War, Britain—facing diminished material power and no longer capable of exercising global primacy—has pursued a dual strategy: aligning publicly with the United States while simultaneously cultivating opportunities to influence or recalibrate the balance of power among competing states, including America itself. Within this strategic framework, fostering limited or indirect polarity among major powers has repeatedly served Britain’s long-term geopolitical interests.
A frequently cited historical parallel concerns the Cambridge Spy network. Long depicted as ideologically motivated defectors who provided intelligence to the Soviet Union, figures such as Kim Philby, Guy Burgess, Donald Maclean, and Anthony Blunt also served strategic functions within British foreign-policy calculations. Sensitive materials, including nuclear information, were transferred to the Soviet Union, with Maclean even placed within the U.S. Manhattan Project. When their usefulness diminished, these individuals were either abandoned or selectively protected. Philby, for instance, reported in his memoirs that the Soviet state never fully trusted him, suggesting that his activities may not have aligned neatly with the conventional narrative of ideological defection.
Contemporary Resonances: The Imagination Technologies Case
A contemporary illustration of these dynamics emerged in testimony by Dr. Ron Black, former CEO of Imagination Technologies. Appearing on BBC Panorama (17 November 2025), Black stated: “I think in the fullness of time this is going to be recognised as the biggest intelligence failure since the Cambridge Five.” As argued here, the episode is more plausibly interpreted not as an intelligence failure but as a reflection of deliberate policy choices.
According to Black, China Reform—an investment vehicle linked to the Chinese state that gained control of Imagination Technologies via the firm Canyon Bridge—explicitly requested the transfer of proprietary technologies “from the brains of the British engineers to the Chinese engineers.” When Black refused and alerted selected government officials, he was informed that the issue constituted a “private industry matter.” China Reform subsequently claimed that the UK government had vetted the acquisition, and Panorama reported that following Black’s resignation, the relevant technologies were indeed transferred to China.
External observers have also raised concerns. AidData, a U.S.-based organisation tracking Chinese global investment activities, has noted that the UK had enabled Chinese access not only to semiconductor technology but also to Europe’s aerospace supply chain through acquisitions such as Gardner Aerospace, a British supplier to Airbus.
Britain’s Dual Messaging Strategy
The UK’s permissive stance has been accompanied by a careful public-relations strategy. On one hand, political leaders frequently articulate concerns about Chinese espionage or coercive economic practices; on the other, the government has consistently avoided designating China as a formal national-security threat. This approach allows Britain simultaneously to reassure domestic audiences and maintain economically valuable ties with Beijing.
This dynamic helps explain a number of high-profile but inconclusive public allegations of Chinese espionage—such as the cases of Christopher Berry and Christopher Cash—that were later dismissed, with officials noting insufficient evidence to classify China as a national-security threat. Under political pressure, the government commissioned a classified “China Audit,” but its findings were withheld from public release. Dame Emily Thornberry MP, Chair of the Foreign Affairs Committee, noted in Parliament that instead of the promised comprehensive review, “we were given three paragraphs on page 39 of the National Security Strategy,” leaving both Parliament and the public with “more questions than answers” (UK Parliament, 8 July 2025).
A Consistent Strategic Pattern
Britain’s contemporary behaviour reflects a long-standing strategic pattern: the pursuit of economic engagement with a rising power while maintaining a public façade of alignment with the United States. By quietly enabling China’s technological rise while signalling concern over Chinese influence, the UK has contributed to increasing structural tensions between the world’s two largest powers.
Historical analogies reinforce this interpretation. It was only after a personal meeting between Nikita Khrushchev and John F. Kennedy in the aftermath of the Cuban Missile Crisis that both leaders reportedly concluded that Britain had exacerbated Cold War tensions in ways that contributed to prolonged military and economic strain on both superpowers.
Taken together, these historical and contemporary cases suggest that Britain remains one of the least predictable and most strategically dexterous actors in the international system—operating through indirect, often opaque mechanisms to shape geopolitical outcomes from behind the scenes.
