7 January 2008 UTC Well after WW2 they had already struck a deal to return Japanese colonies back to either RO China or Korea with the exception of Okinawa which btw was itself influenced by different groups Actually ethnicity and culture are not good arguments considering the 70 of Taiwanese are Hoklos and 15 Hakka both classified as a branch of Southern Han while the rest is 12 various mainlanders and 3 mixed Aborigines Culturally they re a typical East Asian nation The reason why they re separate is because they were founded by the refugees of the ROC making them a separate nation 09 18
