SAARC is an eco-political organization established in 1985 by 8 South Asian nations to promote friendship, cooperation, and development. Covering over 2 billion people, it is the largest regional organization in the world. Its goals include improving welfare, economic growth, social progress, cultural development, self-reliance, and maintaining peace in the region. Member states include India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Afghanistan, and Maldives. While opportunities like increased trade, counterterrorism cooperation, and youth programs exist, challenges include political and cultural differences as well as tensions like the India-Pakistan relationship and water disputes. Benefits to Bangladesh could include poverty reduction, increased revenue, and skills exchange.
