Ask yourself why you asked your question in English but not in any other languages and you will find that out.

Why is English so important to/for Asian people? - That's a better way to ask the question.

I can't stand for most Asian people,but most Taiwanese think that English is the first way to let us understand and contact the world.

Learning English offers alot of opportunities in careers and education, especially in English-speaking countries, where you will find it easier to converse with the local population.
