It's always perplexed me as to how several disparate economies with disparate strengths (and economic models, it seems) managed to develop so rapidly. I could ask the same question about the West, but we have popular explanations for that (first to industrialise, colonialism, etc.)
How about East Asia? How did the economies of Japan, HK, Taiwan and S. Korea develop so fast? And with China catching up apace? I don't think they are abudant in natural resources. Either, unlike the Gulf states.
