This report describes an era where large-scale migration combined with an increased rivalry between democratic and authoritarian states have made "human geopolitics" take centre stage on the international arena. This is happening mainly by states actively formulating policies in relation to their diasporas, not least authoritarian states using these policies to try to influence members of the diaspora (sometimes referred to as "extraterritorial authoritarian rule"). In a context where a large and growing share of the populations of many countries, such as Sweden, have their roots in states of this kind, the overarching aim of the report is to add to the knowledge base necessary to best handle these influence activities. This, in order to protect the security of both the state, and of individuals residing within it. The report is based on previous research and other sources describing different forms of influence activities from five authoritarian states: Iran, China, Eritrea, Syria, and Russia. The current state of knowledge for each of these countries is detailed, in order to describe the aims and methods for their influence activities. These aims and methods are then analysed, and key areas for future research are identified. The conclusion is that influence activities of this kind constitute a large and growing problem, where aims and methods vary in a way that makes comparisons possible, in order to reach a deeper understanding of the phenomenon under study. Among other findings, it is clear that while some states focus only on influencing the diaspora for internal, regime stabilising purposes, other states also aim to achieve strategic, foreign policy goals. Taken together, the development detailed in the report is a serious challenge for liberal democracies like Sweden, not least in finding a balance between protecting the security interests of the state, while at the same time protecting the democratic rights of the individual.
