The extent of my knowledge is that when Taiwanese individuals would like to travel to China for business and/or pleasure they can not use the same passport they use for travel elsewhere. Instead they must apply to China for other travel documents specific for this purpose.
During this process I believe there is a statement that must be signed. I don't know, but my guess is that it has something to do with "clearing up ambiguities" with how One China is interpreted.
So I'd like to ask:
Question: What are Taiwanese required to do and sign to travel to China? Can active, reserve or retired military do so?
Taiwan's military has several branches of active military as well as an armed forces reserve; I'm curious if Taiwan allows them to go through this procedure.
note: I understand that there will be some who may take exception with the wording of my question because "they can't travel to China because they are already in China" and others who may take exception to that! I don't know if there is a way to word this question in an absolutely neutral way that everyone will be happy with, but let's just keep the focus on what is required to do and sign and who can and can't.
