Diasporas have emerged as powerful entities since they are recognized as ‘soft power’ in the realm of foreign policy strategy and also as an agent or catalyst of economic development of countries of origin beside their active role in the host countries. For instance, in the economic sphere, the Chinese Diaspora has been seen as a propelling force for its emergence as an economic super power. In the political sphere, the Jewish Diaspora has a strong grip over the US and European Union in terms of shaping their strategic relationship with Israel. Hence, Diasporas being transnational communities have become important non-state actors as well as deciding factors in international political and economic relations. One could argue that Diaspora policy and Indian foreign policy are two sides of the same coin. As discussed above, it is productive and counter - productive as well. India is yet to utilize the potential of Indian Diaspora in its domain of foreign affairs. For instance, India has been demanding for permanent seat in the UN Security Council, but it has not been realized so far. Indian Diaspora can be utilized for achieving the long due aspirations of India. In the recent decades, the international migration of semi-skilled and high skilled Indians has seen an upsurge due to demand of software Industry and H1-B visa phenomena. A tangible and scrupulous Diaspora policy is imperative to leverage upon the growing Indian Diaspora population. With the versatile role of Diaspora, India could fulfill its cherished dream of being a super power and it could make much head way in its international and foreign affairs. This book is an attempt to analyze the impact of India’s diaspora policy with regard to Indian diaspora in Southeast Asia.
