Britain has been harsher on China than anybody in the EU for a while now.
E.g. the UK is one of only four countries in the world that have the balls to formally recognise the Uyghur Genocide as a genocide. The UK offered asylum to over 3 million Hong Kong citizens. The UK sanctioned china over attempts to infiltrate the UK's Electoral Commission. The UK got into a spat with China over them hacking some MoD server. Several Chinese spies have been charged by the UK, etc...
UK-China relations were already rocky even before the bullshit in Hong Kong (which as you can imagine is a big issue for the UK and not others) and Russia invading Ukraine (in which the UK has been one of the top supporters of Ukraine), and it's got worse from there. Clearly you're talking about something that you know nothing about.
You're letting your xenophobic attitude towards the UK cloud your judgement. Put your hate aside for a moment and actually look at reality.
