Can I expect to encounter any problem when visiting the Republic of China (Taiwan) after visiting the People's Republic of China or vice versa?
I mean, some countries have political clashes with each other, and sometimes such clashes just poison a traveller's life. It happens sometimes that a passport with stamped visa of one specific country is not even recognized as a valid document by another country.
UPD: I'll be most probably on Russian passport, but I believe it would be nice if you can provide any kind of information on this issue, specific to whatever citizenship - just like @Tom Squires have done. So it can be useful to any traveller as well.
