The project aims to investigate growing divergence between countries’ inward foreign investment policies and their increasing links to national security. Novel interdisciplinary collaboration integrating political science, economics and law promises insights into these policy shifts, which appear driven by digitalisation of the economy and the rise of emerging markets (eg China) and State-linked investment. Expected outcomes include clarification of the causes and implications of these shifts and innovative understanding of the connection between national security and economic interests in investment. This new knowledge should enhance balance in investment policy and decision-making, with economic and foreign policy benefits for Australia.
