In recent times, the European Commission has shown to have increasing difficulty keeping up its central position in trade diplomacy towards China, in the face of a growing wariness and assertiveness of the member states. In this article, we observe a changing balance, a development from EU diplomacy towards European diplomacy, meaning a growing influence of EU member states in the process. We call this the “Europeanisation” of EU economic diplomacy. This is not limited to China and reflects a broader development, as is visible in the politicisation of the negotiation processes towards the (failed) Transatlantic Trade and Investment Partnership (TTIP) and the (provisionally applied) Comprehensive Economic and Trade Agreement (CETA) between the EU and Canada, and also in the trend towards mixed agreements that require member state ratification. However, it was particularly in the relations with China that such trends became visible for the first time and have continued to manifest themselves throughout the years. Apart from the member states assembled in the Council, also the European Parliament has strengthened its position in the process at the expense of the Commission.
