Hahaha... I think it's indeed a Filipino thing? We do have some foreign brand noodles in the international section in some supermarkets. Though there are some Korean or Japanese shops in some places. I haven't fund any Cambodian noodles here, though.
I guess the Philippines is pretty much a mixture of various cultures including food. We even have our Filipino version of Spanish foods like chorizo, paella, empanada among others. ^^
