Book excerpt: This book focuses on the role of immigrants in building economic, social and political relationships between countries. In this era of growing global interconnectedness, international migration and immigrant issues have become a significant source of disunity between countries. In some receiving countries, immigrants are now workforce replacements for an ageing population, while in sending countries immigrants use the experience gained in their country of residence for investment and entrepreneurial activity in their country of origin. This has led to the suggestion that immigrant activities are no longer a process of bridging the economic imbalance between nations, but rather the bridging of economic, social and political relationships.Transnational diaspora entrepreneurial activity relies on the relationship between immigrants and their home country, their understanding of the economic, political, and social systems in both their home and host countries, and the demand for their home country's cultural goods. As the demand for home cultural goods grows, there is a need to establish businesses that can operate across multiple environments. This book posits that transnational diaspora entrepreneurship can be seen as the internationalization process of immigrant entrepreneurship. It explains the role of enclaves in supporting this activity and offers valuable insights into how immigrant enclave activity and informal networking influence transnational diaspora entrepreneurship.
