South Korea (per capita GDP $24k) is hardly the only success story in that part of the world. Japan ($38k), Hong Kong ($38k), Singapore ($55k), and Taiwan ($20k) have basically pulled off the same trick. All these places have in common that they are either Chinese (mostly Chinese, in Singapore's case) or very closely related culturally to China (Korea and Japan are more closely related to China than, for example, Laos or Myanmar). They are all small, without huge agricultural potential or much other resources, but with good access to the sea.
A more recent, and possibly more relevant example is Malaysia ($11k). Malaysia is an interesting case. It is majority Muslim, but it has a significant non-Muslim Chinese minority that controls most of the economy. It is a large petroleum exporter, but it has successfully expanded to manufacturing and services, arguably escaping the "resource curse".
You might be tempted to conclude that Malaysia pulled this off because of their Chinese population (and I know some Malays have said exactly this), but there are counterexamples to this - Thailand ($6k), Indonesia ($4k), Vietnam ($2k) and Cambodia ($1k) all have significant ethnic Chinese populations. On the other hand, ethnic Chinese control business in all those countries far out of proportion to their share of the population.
What useful lessons Arabs can draw from this I have no idea. Well, I have some idea: just look at North Korea ($0.6k) and Vietnam ($2k). The lesson isn't just simply "communism is bad" though, because they are well behind Russia ($15k) and even Cuba ($6k).
