Please see the post in the Taiwanese Identity blog.
A few quotes:
"Whereas Ma Ying-jeou pretended to a Taiwan-centric consciousness during the presidential campaign, upon his election and inauguration, he has pursued the ruthless Greater China ideology of the authoritarian one-party KMT dictatorship of his father's generation."
"Fortunately for the Siraya people, they had registered their ethnicity in the Japanese colonial era, and some had taken very unique Han surnames. So their descendants have been able to ascertain their ancestry and now seek to reclaim their cultural heritage while throwing off the Han culture that was forced on their ancestors.
But with the colonialist "Greater China" ideology of the Chinese Nationalist Party now currently in power in Taiwan, any attempts to revive non-Chinese Austronesian culture are either treated with neglect and indifference or even suppressed if neglect and indifferent do not do the trick to put out the fire of the cause."
The Taipei Times has an April 23, 2009 article exposing the Ma Ying-jeou administration's opposition to the struggles of the Siraya people to restore their ethnicity.
