Other than unified, that describes most places in the 15th or 16th century.

The one country in Asia* to not suffer colonialism (Japan) is way ahead of all the others that did have it, especially on "Eurocentric" metrics such as GDP and productivity and democracy and human rights. That alone should be a rebuke to colonialism's purported development powers.
* Arguably Thailand is another but it was forced to cede land to colonial powers. It too is considerably richer than its immediate neighbors.

I don't think this is a good example, given the actual modern history of Japan.
Contemporary Japanese democracy and respect for human rights aren't indigenous Japanese developments. They were literally forced on Japan by the victorious Americans after the homegrown Japanese militarist empire, which didn't GAF about either, catastrophically lost a major war.
