The Treaty of Lisbon: Half Way Toward a Common Investment Policy

Abstract

As a follow-up study on the external investment policy of the EU, this article attempts to analyse the relevant provisions in the Lisbon Treaty and assesses their legal implications on the international investment treaty practice of the Union and its Member States. It first briefly reviews the EU's foreign investment competence before the Treaty of Lisbon, followed by an assessment of the different views concerning the interpretation of the Lisbon Treaty provision including ‘foreign direct investment’ under the common commercial policy. The practical legal implications of the change are discussed in the third part, including intra- and extra-EU investment treaty practices. It is concluded that while the change is significant and will greatly enhance the treaty-making competence of the EU in external investment areas, it is only a half way success toward a full common investment policy (CIP). Potential paths to achieve the ultimate goal are also briefly explored.
