Probably yes, I've hit the language barrier many times in the past; not being a native English speaker and having spent less than 2 months combined in my entire life in English speaking countries comes at a price:)
> Actually why would Russia interfere or react to China/Taiwan in any way, regardless of Ukraine?
Pure speculation, but it is possible that both Russia and China will support each other, at least through economic pressure or threatening military action against the US and NATO countries, so that the US are forced to keep the guard up on multiple fronts because, should the shit hit the fan on one front, they could deploy only part of the available personnel and gear.
That would work as hell of a deterrent, and I'm pretty sure that if it happens on one front, let's say China invades Taiwan and the US intervene militarly, something nasty would happen also on the Russian front, like Russia getting the chance to attack some EU or NATO country so that the US would be forced to divert part of their force there.
Since never; I wrote the exact opposite. About the rest, only time will tell.
