A ‘rule of law’ approach would promote mutual agreements and investments, but be much tougher on their implementation. For example, the European Commission should be given political support to apply competition policy in the energy sector, and to investigate some of the more dubious deals between Russian and EU companies. More generally, the EU should demand the enforcement of the growing number of agreements which have not been implemented – the PCA, the four Common Spaces and the European Energy Charter. Ignoring Russian foot-dragging undermines the very principle of a rules-based relationship with Russia. .
