The diaspora is now recognized as an international influencer. Apart from its role in economic development, it plays an important role in bilateral relations between the host country and country of origin. It has emerged as a major driver for the foreign policy of countries with substantial overseas communities. Globalization enables it to serve as a resource both for the host and home country. It has created an environment for communities to look beyond rigid national boundaries for economic and cultural needs. Even developing countries have matured now to permit extraterritorial loyalties. Many of them are using their own diaspora abroad as well as the diaspora within their territory as an important resource to realize their national objectives. Cheaper and faster means of communication at a global level provide opportunities for different diaspora to network and come together. The emerging scientific and technological advancement and global media have further enabled the different diaspora and states to engage with each other.
