No. Why would they be? If you believe that China is a "threat to UK national security", could you spell out exactly how? The video you posted most certainly didn't, although it referred to this "threat" multiple times, the alleged threat/s remain unspecified. The threats are the other way around in reality.
Currently cyberthreats: Jaguar Landrover, Marks and Spencer, Harrods, the Co-op. I'm sure you've heard of the proposed new embassy in Tower Hamlets, the largest in Europe with its spy dungeon for interrogating dissidents and intercepting information communicated via underground cables.
There's the ever-existing threat against Taiwan, which provides most of Europe's semiconductors. China has cracked down on democracy in Hong Kong, a violation of the Thatcher-Howe agreement of One Country-Two Systems, which was supposed to endure for fifty years from 1997.
Given your preoccupation with genocide around the world I'm surprised you're not concerned about the Uighurs. Anyway, I'll let Iain Duncan Smith continue the talking.
