Two Germans, two Koreans, why can't two Chinas? No such a thing such as "One China" --- It has been always "Two Chinas". Isn't good if we have 2 Chinese seats in UN? If you want to conquer then no need to discuss, go ahead...
The “One China” Principle is a principle held by the PRC, which is, in my opinion, antiquated and unhelpful for solving the current cross-strait impasse. It doesn’t solve the question – it only worsens it. Under the One China Principle, the Taiwanese are forced to separate themselves further and further away from the mainland – not necessarily that they want to, but because they have to in order to survive. That is a sad fact that has been ignored by many mainlanders.
Not only that, you are also encouraging the pro-TI forces: you are daring them to abandon China (Republic of) so that they may pursue more international space. As the last 8 years have shown, the percentage of Taiwanese identifying with “China” and “Chinese” are on the decline. I believe that is caused in large part by PRC’s erroneous One China principle.
The laws that you talk about could not adequately explain the current status: that there are two separate political entities in existence under this entity known as “China.” Neither state could represent the other right now – and I think you agree with that notion too. The “One China” principle is only applied toward foreign countries, which, in the end, resulted in two effects: (1) Taiwan’s friends and international space are reduced, and (2) as a result of (1), Taiwanese people resent the mainland government more and more and desire unification less and less. The “One China” principle might be successful in isolating Taiwan, but, in the end, it loses the heart of the Taiwanese people. That is not a good trade.
(BTW: the territory encompassed under the ROC and the PRC are actually different. Take Mongolia, for example.)
To me, the Germany model: the “dach theory” is the better way to resolve this. The “roof” of “Germany” covers two states: East Germany and West Germany. However, both of the two Germanys remained an independent state, free to engage in relations with other countries, while “Germany” was still alive and represented by its two components. And, it should be noted that, when the West Germany took this approach, they were actually more successful in winning the hearts of the East Germans – not by squeezing out their international space, but by proposing a win-win solution for both sides. The same thing happened between the North and South Koreas.
And I think that’s what Mr. Yang meant. There is no point in pursuing the “One China” principle now – politically, it only pushes Taiwan further and further away and gives TI supporters greater reason to do what they do.
In the end, if you want to solve the Taiwan problem by force, then there’s no point in discussing the above. Since no one wants to take that approach (and whether it will work is still highly suspect), we must look for other options. Mr. Yang is pointing that out – squeezing out Taiwan’s international space will not work. We already know that from the last 8 years. In order to make the Taiwanese people want to unify with the mainland, a different approach must be taken. The Germans used the “dach theory,” and the Koreans used the “sunshine policy,” both of which, although imperfect, have worked much, much better than the “One China” principle that you speak of. And I think it is time to learn from the Germans and the Koreans.
