'The present monograph is a welcome treatise on services in the EU and the WTO. The author has done enormous works having analysed two systems of services regulation not in isolation but having tried to make a systematic comparison. Both the EU and the WTO system are looked at from a different angle, which gives an opportunity to discover new constellations and issues. The present monograph is a useful and recommendable work for readers who wish to deepen their knowledge and understanding both of the General Agreement on Trade in Services and regulation of services in the European Union law.'
