The twenty-first century is witnessing the first time in history, asserting two powers—India and China in Asian continent, they are attempting to bring change in global politics. India is the biggest country in the South Asian subcontinent. The other six countries are not positive about the role of India in the subcontinent. As, Bhabani Sen Gupta in 1984 described the prevalent such perspectives as “the Big Brother Syndrome”. The spatial dimensions of the present work, however, extend to the South Asian subcontinent and beyond that up to China, but the central point of the discussion revolves around India’s increasing role in cooperation and collaboration in resolving regional political and security issues. The book has captured diverse dimensions of an actor (India) such as demographic, social and cultural, economic, political, technological, and ecological, which employed for positively engaging with other actors in the region. The contributors in the book see links and convergences between their perspectives. Their perceptions of the India’s role (of an actor) reflect new openness to internal and external influences that has led to change in the existing perspectives about the actor (India) in the region (South Asia).
