"The Kuomintang holds the "One China Principle" and maintains its claim that under the ROC Constitution (passed by the Kuomintang government in 1947 in Nanjing) the ROC has sovereignty over most of China (including by their interpretation both mainland China and Taiwan)...Former ROC President Ma Ying-jeou had re-asserted claims on mainland China as late as October 8, 2008."
The interview was published yesterday.
Ma said despite the stipulation of the ROC Constitution, Taiwan cannot recognize the existence of another country, nor does China want to recognize Taiwan. In other words, under the ROC Constitution, “mainland China” is not a country."
