In the politics of Taiwan, both terms are used to refer to an increase or decrease in cultural and economic ties with Mainland China. Both terms have been used more commonly after 2001. Since the 1990s, there has been general consensus in Taiwan in favor of the political status of Taiwan, though there is some debate about what that is. There is also general consensus that Taiwanese localization movement is favourable. That is, emphasizing local culture and language.
Also, the argument in the Republic of China on Taiwan between supporters of Chinese reunification and supporters of Taiwan independence is considered a matter of sinicization. Supporters of independence are generally wary of increasing cultural and economic links (such as the three links) with Mainland China. They feel it is part of a strategy by the People's Republic of China to sinicize Taiwan, thus making reunification inevitable.
Another meaning is the process by which other peoples like the Koreans and the Japanese are influenced by Chinese culture and working practices. An example of this is the kanji writing system of the Japanese language.
