Let me help you with the answer there since it is rather obvious. Let's start with South Asia. China, India, Pakistan and Bangladesh notably cannot seem to agree on anything. For starters there is yet to come a formidable bloc in Sth Asia. Even developing African countries managed to create formidable blocs to serve the interests of their regions. The European nations are by and large masters of creating formidable blocs which includes the USA and Turkey to secure the bloc's interests. Russia has its own bloc in Eastern Europe. South America has created their blocs which includes Cuba. Come back to Sth Asia and the only pragmatic nation is China which is starting to create a common economic sphere. India and Pakistan as neighbors can't even agree on an economic bloc let alone a political bloc. Bangladesh is the filling in the sandwich which gets yanked inbetween India and Pakistan. The situation in Burma is bad. Sth Asia is impotent to act since they are divided. The rest of the world is too busy tending to their own backyards to bother about a few hundred Muslims getting massacred regularly in some far off place unimportant to them. Hopefully Sth Asians will realise the importance of political and economic co-operation. In my view a genocide is starting to happen and India and its neighbors are each pointing to the other and saying "you do something about it." Someday, the dark skinned people of South Asia could rise up and start slaughtering the fair skinned people there or the tall people may start slaughtering the short people and you will still be asking the same question whilst the answer remains obvious
