Being sustainably successful for hundreds of years?

I mean, China is the only successful country that isn't western, not even in spirit (like India, Japan, or Korea) and their run seems coming to an end lately, with all their debtors defaulting.

Causing two global conflicts isn't what I'd call 'sustainably successful'. Since those, I'd agree with you, but definitely not hundreds of years.

Not?

The Indian trading companies seem to have left the west in a very good position.

I m not sure if this is fully accurate though, especially about Japan and South Korea part. Both of them have demonstrated solid economic prowess in the last few decades & if you ignore a few decades of colonial interlude and look back further - they still have had sound economies in previous centuries. I think Singapore , Taiwan and even may be UAE are missing from this list ( depending on how much further back in history you are looking at).

I think GP meant that unlike China these countries are "part of the West" now, not that they are unsuccessful.

Yes.

They are successful and follow the "western spirit" more than the rest of Asian countries.
