It occupies a central place in the Community decision-making system, in which it is both a forum for dialogue (between permanent representatives and between them and their national capitals) and a political control body (defining guidelines for the work of expert groups and their follow-up). In practical terms, a common strategy defines the objectives and duration of the overcast time, as well as the means to be made available by the Union and the Member States. Common strategies are implemented by the Council, including the adoption of common actions and common positions. The Council can recommend common strategies to the European Council. an agreement between two or more people, groups or countries in which they agree to cooperate to achieve something. They require strengthening of legal administrations and systems and a drastic adaptation of the infrastructure of candidate countries to EU standards, particularly in the areas of environment, transport, energy and telecommunications. In order to facilitate these important adjustments, pre-accession assistance is granted to the candidate countries. A European agreement is a specific type of association agreement between the European Union and certain Central and Eastern European states (Article 310 of the EC Treaty). Its aim is to prepare the associated state to join the European Union and it is based on respect for human rights, democracy, the rule of law and the market economy. So far, European agreements have been concluded with ten countries: Bulgaria, the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Romania, Slovakia and Slovenia. Turkey has association agreements with the EU covering the same areas as those with Central and Eastern European countries (with the exception of political dialogue) and its aim is to create a customs union. Future challenges include promoting closer cooperation between national administrations and combating fraud through successive customs programmes in 2002 and 2007.
