I guess Myanmar would be the westernmost Southeast Asian country, and Bangladesh/Indian is the start of South Asia. But hey, I'm an American, and there are many ASEAN Hivers that aren't from Southeast Asia nor living there. As long as your content has a Southeast Asian element to it, it's welcome in this community. Maybe a post about a really good Thai restaurant in Pakistan, or similarities between South Asian and Southeast Asian culture/ways of life, etc.
