The Lisbon Treaty transferred competence over foreign direct investment from EU member states to the EU level. This has implications for existing bilateral investment treaties between member states and other countries. To manage this transition, the European Commission plans to adopt a regulation that will grandfather existing member state BITs and delegate investment competence back to the member states. However, the details of how the Commission will exercise its new investment powers have not yet been clarified, leaving many questions about Europe's future investment policy approach.
