China is an economic competitor to the US while Russia is essentially not. China controls a lot of the supply chains that the US depends on which gives it great but subtle power. It's not in the interests of a nation to allow another nation that much control over the items it depends on. They may not use that power right now but that can change at any moment and there may less public uses of that power. Same reason China (and Russia) pushes home grown companies over foreign companies.

At the same time, the US controls the financial monetary system (petrodollar), dominates the world military-wise, tech and so on. If one is able to follow this logic, does that mean that Europe and other countries should also take hostile measures against the US since they control "supply chains" and has "great but subtle" powers over them?

Yes they should and in some ways they are with various laws aiming to curb the power of large (US) tech companies. They also seem to have stronger laws protecting domestic industries than the US although I might be wrong. Europe failing to protect itself properly against either the US or China (see how much of UK infrastructure is owned by China) isn't an argument for other nations not doing so.
