As
@GiantKiwi mentioned when it comes to the actual spread of covid from parts that arrive from China you should probably consider that the virus itself cannot survive outside of a biological host for very long - typically a few hours, but up to 72 hours (unless the findings of this research has changed in the last couple of weeks). This being the case, you are more likely to get the virus from within the UK logistical side of things (so the postman or other courier) than you are from a Chinese product packed up in one of their factories.
But as far as getting away from ACM goods for moral reasons is concerned, as everyone's saying it is very difficult - I think even the South Korean companies have their stuff made in China.
The problem is, from a commercial perspective it makes very little sense to have something manufactured anywhere but there - even if you want decent QC; they can accommodate that too these days; I was watching a OnePlus factory QC tour video a few months ago, and they are a Chinese company building their own phones, and from what I can tell they are meeting the same standards as Korean and US competitors.
I think companies like Oneplus and Huawei show that dependence on China is only going to grow and even more so towards the top line products as they'll be catching both ends of the market.
