With the reorganisation of leading EU posts under the Lisbon Treaty, there was some criticism of each post's vague responsibilities. Ukrainian ambassador to the EU Andriy Veselovsky praised the framework and clarified it in his own terms: The Commission president speaks as the EU's "government" while the president of the European Council is a "strategist". The High Representative specialises in "bilateral relations" while the European Commissioner for Enlargement and European Neighbourhood Policy deals in technical matters such as the free trade agreement with Ukraine. The president of the European Parliament meanwhile articulates the EU's values.
