Will Chinese soldiers be stationed in Poland and Europe in 10 years?

And that's where you might be wrong. Poland has good relations with China and doesn't recognize Taiwan as a separate state which only improves these contacts. However, unofficial contacts with Taiwan are maintained.

I hope these 'geniuses' in charge won't conclude under some US pressure to recognize Taiwan. That would be treason.

Even the US does not recognize Taiwan, but they unofficially help them, as do many other countries.
