That's spot on. Also don't forget the EU-US Technological Council that is set up in order to block Chinese Tech advancement. Anyone who still believes that EU is "neutral" has probably not kept to to date with news for the past years.
In fact, forget Huawei, the big thing that showed the EU had taken US' side, was them accepting the US ASML ban on selling advanced IC equipment to China.
There is nothing the Dutch/ASML could've really done in that case. ASML would gladly sell China its EUV if critical supplies weren't sourced from China. Again, EU is currently powerless in this semiconductor war due to insufficient investment in this area.
You are probably overly pessimistic about EU/US cooperation. After all, we just had a president that wanted to break up with EU and there is a good chance he will be president again in 3 years. Just 4 years ago, Trump had royally pissed off the Europeans, who were turning to China for more cooperation everywhere. Right now, there is a warming of EU/US relationship due to the Russian scare. In a couple of years, EU countries could very well have a "Russian fatigue" from years of sanction fueled inflation. COVID will be far away from people's mind. And a certain popular figure in America is talking about "America first" on the campaign trail again.
As China develops, there is no reason China cannot sell IC products to Europe just as it has been selling other advanced technology (like NEV) to Europe. Remember, successfully developing semiconductor supply chain gives China power. Only with power, can they dictate the terms at which they engage other parties. Europe may prefer to deal with US, but it will also deal with China if China can offer them what they need.
Let's put it this way, if the Europeans cannot do anything more than adding the occasional anti-dumping tariffs on Chinese new energy exports to Europe (which actually have large European competitors), what makes you think they'd be able to stop China from exporting semiconductor related product? China just needs to develop technologically. Everything else will follow.
