Can I visit mainland China after going to Taiwan?

Hi,

I plan to visit mainland China but beforehand I really want to visit Taiwan. I'm familiar with Chinese Visas and how they work as I've been to China quite a few times so that's not a concern. I can get that sorted however, my only concern is that if I have a Taiwan stamp in my passport will this be an issue when I want to enter mainland China?

If I could get an answer ASAP that would be great. (I'm also a UK citizen and realised there's no specific visa required for Taiwan; only for mainland China).

Thanks!
