TL;DR

China’s foreign ministry dismissed the UK National Cyber Security Centre’s latest warning at a press conference on 4 November, with spokesperson Mao Ning saying Beijing “expresses grave concern over the wanton speculative accusation”. As the question put to the ministry summarised it, the NCSC review had said China would highly likely be using AI-enabled hacking routinely by 2028. A denial was predictable, but the ministry’s choice to tie it to Britain’s standing in AI governance talks is the part UK readers should note.

What was said

The exchange came from a question put by Phoenix TV, whose summary of the review described China as a leading developer of AI-cyber capability and the “most sophisticated and sustained” challenge the UK faces. Mao’s reply, according to the ministry’s transcript, said the accusation came “despite the absence of evidence”.

The sharper line followed. “Regrettably, the UK, having long politicized the cybersecurity issue, is now rehashing hacking allegations as a pretext to curb China’s AI development,” Mao said. This kind of action, the transcript adds, “hurts the UK’s credibility when it comes to cooperation on global AI security governance”. The ministry’s alternative is new rules formulated at the UN.

Syria’s state agency SANA carried the remarks on 5 November, attributing them to Xinhua and placing them on the Thursday. The ministry’s own transcript is dated the day before, and we have followed that.

Reading the exchange

We covered the NCSC’s review when it appeared on 3 November. Neither side’s statement here settles the underlying question. The ministry offers no evidence of its own, and it speaks as an interested party. Nor does this exchange test the NCSC’s assessment, which is a forward-looking judgement.

In our view, the useful signal lies in the diplomatic framing. Beijing is presenting UK security warnings as a form of technology restriction, and it is linking them to Britain’s role in international AI discussions. That matters for any UK attempt to build broad agreement on frontier AI, on which Beijing here says it wants rules made at the UN.

Looking Forward

Watch whether the UK government responds publicly, and whether the argument reappears in multilateral AI talks. For UK businesses, nothing here changes the practical advice: a foreign ministry’s denial does not alter the NCSC’s guidance on defending systems. Boards reading both statements should treat the 2028 judgement as what it is, an estimate from the UK’s cyber authority, disputed by the government it names.
