The Nordic Council became more outward-looking, to the Arctic, Baltic, Europe, and Canada. The Øresund Bridge linking Sweden and Denmark led to a large amount of cross-border travel, which in turn led to further efforts to reduce barriers. However, the initially envisioned tasks and functions of the Nordic Council have become partially dormant due to the significant overlap with the EU and EEA. In 2008 Iceland began EU membership talks, but decided to annul these in 2015. Unlike the Benelux, there is no explicit provision in the Treaty on European Union that takes into account Nordic co-operation. However, the Treaties provide that international agreements concluded by the Member States before they become members of the Union remain valid, even if they are contrary to the provisions of Union law. However, each Member State must take all necessary measures to eliminate any discrepancies as quickly as possible. Nordic co-operation can therefore in practice only be designed to the extent that it complies with Union law.
