I don't get the US paranoia about Russia. It is a nuclear country so from a military perspective it requires attention. But from a technology perspective? As a market it is smaller than Germany, France, UK or Italy and, thanks to sanctions, its struggling. Its GDP per capita is one third that of any western state. And why are tech companies not part of the embargo on Russia?
China is a different case - at least to me, a European. The US hegemony on stuff technical is dangerous for the prosperity of Europe. Sure, we get to use it but it sucks cash and talent out of Europe. Meanwhile Europeans seem totally incapable of forging a common technical market to rival the US. So China offers Europeans the prospect of an alternative technical nexus. No matter how significant China becomes, like the US it is too far away to be a political or military threat to Europe. But the prospect of having a second vendor to the world (not just a manufacturing shop) would introduce real competition.
