Two examples: 1. A decade or so ago, in my capacity as a tech entrepreneur, I was in chats with some engineers at a certain well known UK University. I went to visit the Uni's core technology lab re a joint venture. It was staffed mainly by young Chinese, who were very odd in their behaviour, but at the time, I did not know anything about the Chinese efforts to infiltrate our institutions. A wealthy Chinese woman who was involved tried to lure me (and other British business people) to her home somewhere else. I declined. 2. Later I want to a mixer in London held by our patent attorneys at the time. All the company partners were there along with clients. Much alcohol being consumed. I got to talking to a Chinese lady who had bene working for the firm but told me she was looking for a new job, and asked me for a role. She said she had previously been working for the UK government. She was very inquisitive and I did find it all very concerning. I did not take things further.
Fast forward to today, with Chinese part ownership of some of our critical infrastructure utilities including a water company, and I can see the big picture now. China has inserted or been trying to insert it's tentacles everywhere. This is immensely serious. I am glad I did not release any of my companies IP, even under NDA.
Ironically, I do buy solar panels from Longi via UK's City Plumbing, but they are good, and there is no risk to national security in doing so. Our solar electronics are from Victron, a Dutch company, so China cannot disable our energy generation!
It was obvious China used Covid to make a killing, mainly via al the PPE tat.
UK government were fooled hook line and sinker. Trump has always known China is a threat, he's a superb judge of character and saw through their smiles and BS.
