Give the history a look and you'll know why.

Unlike in Europe where people choose to unite and live largely peacefully after many conflicts (2 world wars got people fed up especially quickly), Asian countries landed themselves in a different situation, and reasonably suspicious towards "outsiders". What makes things even worse is that due to how many of these countries are governed (dictatorships, monarchies, monoparties and fake democracies), the recent movement of globalization is less effective in terms of bringing enough benefits to their citizens to allow them to brainwash their old world views out of their head voluntarily.

Plus, many of these Asian countries don't have enough market ability to support the development of such Internet product domestically. As a result, if you just fully open up your Internet, the majority of the benefit from the action will then be absorbed by some companies located half an earth away while continue to deplete the market demand for homegrown alternatives. This is the situation where when you fully obey the international treaties, you lose.

So, all and all, it's not "the east (just) does things a little differently" ("argh, these uncivilized barbarians" probably follows). Some delicate and sophisticated calculation is involved there.
