MI5, which stands for Military Intelligence Section 5, was originally formed in the run-up to World War I to counter the domestic threat from countries against which we were about to fight i.e. Germany and its allies. Due to the counter-espionage success, its role was expanded to include fifth columnists and Soviet propagandist sympathisers, who worked to overthrow the legitimate government of the United Kingdom. After the Cold War, when Francis Fukuyama told us history had “ended”, MI5 lost its sense of purpose until 9/11, when international terrorism raised the threshold of domestic attacks in western countries. Since then, it has never been busier because Britain created a National Security Register, which now runs to thousands of serials.
Reading the MI5 dire warnings about China by the head of MI5 today, one might be led to believe that the People’s Republic is about to invade a British Territory, or a NATO ally. Whereas in fact, the Armed Forces have been encouraged to share information with China for many years. A good example was the Chief of the General Staff’s land warfare conference, which I organised in 2011. On day 1, at 10.15 after the US Chief of the Army, General Martin Dempsey delivered a keynote address, the next speaker was General Zhang Qinsheng, who as Deputy Chief of the People’s Liberation Army gave a vivid strategic overview. The following day, after Rhett Hernandez, Commanding General of US Army Cyber Command, provided the conference with an update about American cyber capability, he answered a myriad of questions posed by the Chinese delegation (see the unclassified photograph below).
I am sure Sir Ken McCallum is truthful when he states that MI5 is disrupting Chinese intelligence gathering in the United Kingdom, but if we are so worried about this, why are we giving academic scholarships to Chinese students at our prestigious universities, who then have access to incredible levels of private knowledge? And why are we not being consistent with other economic competitors which are also “spying” and attempting to steal copyright material?
Successive governments have fudged this issue partly because China is not a direct military threat to Britain and partly because even though there is a trade deficit, the People’s Republic is our fifth largest trading partner and, according to a government factsheet, we exported £28.8 Billion of goods to China in the four quarters to the beginning of 2025.
