Finland and Estonia, the two peripheral states of the European Union’s north-eastern corner have steadily converged since the fall of the Soviet Union, both bilaterally and in a multilateral European context. The co-operation is significant and covers multiple sectors of society. Now the two countries have set out on a project to join their two capitals by building a fixed link under the Gulf of Finland forming the symbolic twin-capital of Talsinki. This case-study sets out to analyse what motivations there are in creation of the twin-capital, and what relevance does the fixed link have on the regionalization process. The qualitative analysis of policy and spatial-economic documentation triangulated with media sources shows that the incentives are mainly economic, and the process is mainly driven by state- and regional level politicians motivated by regional development. The study also indicates that the rising influence of China and other global actors has an effect on the regional politics of peripheral Europe.
