Taiwan promotes nationalism of its own nation, although it's nowhere near as hardline as the mainland.
> Taiwan promotes nationalism of its own nation
Huh?
Kuomintang for a long time considered themselves a "tru Chinese", carriers of the spirit of the Chinese nation (as opposd to those godless commies).
Regardless of your political views, Taiwan is a different China from mainland China. There are a lot of initiatives to promote a Taiwanese identity such as MIT (Made in Taiwan) and Taiwanization.
I doubt it is Taiwan, the only country I could think of that fits the description is Malaysia.
