China itself is Taiwan's top trading partner

Followed by the US. China does not need to "pressure its trading partners".
Taiwan has its own currency, does not pay tax to the mainland, has a real democracy, and is an ally to the US.
Chinese passports can devote a page to whereever they want, it means nothing.
Interesting fact... phone numbers in the Taiwanese capital begin 02. That's because when the KMT invaded, they reserved 01 for Nanjing, their base of operations when they were the mainland government, and for whatever reason they wanted to believe they would be able to retake it.

Does this mean Taiwan owns Nanjing? :-) Nor does the passport page act as a deed of ownership for Taiwan...
