You assume all developers from Asia/Pacific are familiar with Chinese. Speaking as one of 1.2 billion Indians, we are not familiar with Chinese, despite being firmly in Asia/Pacific. I doubt the Japanese, Koreans, Malayasians or Filipino are familiar with Chinese either. (familiar = to the point of being able to read it)

Just because a language is accepted at the UN doesn't mean everyone should be familiar with it. Even the UN needs translators for Arabic, Spanish, Russian, French and Chinese; all official languages. (Aside: the UN Secretariat uses only English and French).

Being a UN accepted language shouldn't be a criterion for programming, being popular among developers should be. And anyone writing any piece of code in any human language, be it English or Chinese, should know that by making that choice, they are also limiting the set of understanding eyes that can be laid on their code.
