The United States has suspended a recently agreed technology partnership with Britain, injecting fresh uncertainty into the transatlantic relationship as Washington presses London for broader trade concessions beyond the tech sector.
According to reporting by the Financial Times, the U.S. administration halted progress on the so-called Tech Prosperity Deal last week, despite the agreement having been unveiled earlier this year as a flagship framework to deepen cooperation in artificial intelligence, quantum computing and civil nuclear energy. British officials have since confirmed the suspension, though neither government has formally commented.
The Financial Times is gated, but Reuters summarised the report.
The move appears to reflect growing frustration in Washington over what it views as the UK’s reluctance to address a range of non-tariff barriers, including regulatory and standards-based restrictions affecting food products and industrial goods. U.S. officials are said to be seeking concessions in these areas, signalling that the technology partnership has become entangled in wider trade negotiations.
The suspension underscores the increasingly transactional nature of U.S. trade policy under President Donald Trump, with sector-specific agreements now more tightly linked to broader market-access objectives. While the tech deal was framed as a strategic collaboration aimed at strengthening Western leadership in advanced technologies, it has become leverage in talks over trade frictions unrelated to digital policy.
The setback is notable given the scale of existing U.S.–UK economic ties. The United States is Britain’s largest trading partner, and major U.S. technology firms have already invested billions of dollars in UK operations across cloud computing, artificial intelligence research and data infrastructure. The UK has positioned itself as a key hub for emerging technologies, particularly as it seeks to differentiate its regulatory framework post-Brexit.
Although the suspension does not amount to a cancellation, it raises questions over the durability of bilateral tech cooperation if progress on trade issues stalls
