2004年12月17日、欧州理事会は、トルコと加盟交渉を開始すべきであると決定した（詳しくは こちら）。 重要な交渉枠組み（framework for negotiations）について、理事会は以下のように決定している。
The European Council agreed that accession negotiations with individual
candidate States will be based on a framework for negotiations. Each framework,
which will be established by the Council on a proposal by the Commission,
taking account of the experience of the fifth enlargement process and of
the evolving acquis, will address the following elements according to their
own merits and the specific situations and characteristics of each candidate
||As in previous negotiations, the substance of the negotiations, which will
be conducted in an Intergovernmental Conference with the participation
of all Member States on the one hand and the candidate State concerned
on the other, where decisions require unanimity, will be broken down into
a number of chapters, each covering a specific policy area. The Council,
acting by unanimity on a proposal by the Commission, will lay down benchmarks
for the provisional closure and, where appropriate, for the opening of
each chapter; depending on the chapter concerned, these benchmarks will
refer to legislative alignment and a satisfactory track record of implementation
of the acquis as well as obligations deriving from contractual relations
with the European Union.
||Long transitional periods, derogations, specific arrangements or permanent
safeguard clauses, i.e. clauses which are permanently available as a basis
for safeguard measures, may be considered. The Commission will include
these, as appropriate, in its proposals for each framework, for areas such
as freedom of movement of persons, structural policies or agriculture.
Furthermore, the decision-taking process regarding the eventual establishment
of freedom of movement of persons should allow for a maximum role of individual
Member States. Transitional arrangements or safeguards should be reviewed
regarding their impact on competition or the functioning of the internal
||The financial aspects of accession of a candidate State must be allowed
for in the applicable Financial Framework. Hence, accession negotiations
yet to be opened with candidates whose accession could have substantial
financial consequences can only be concluded after the establishment of
the Financial Framework for the period from 2014 together with possible
consequential financial reforms.
objective of the negotiations is accession.
These negotiations are an open-ended process, the outcome of which cannot
be guaranteed beforehand.
While taking account of all Copenhagen criteria, if the candidate State
is not in a position to assume in full all the obligations of membership
it must be ensured that the candidate State concerned is fully anchored
in the European structures through the strongest possible bond.
In the case of a serious and persistent breach in a candidate State of
the principles of liberty, democracy, respect for human rights and fundamental
freedoms and the rule of law on which the Union is founded, the Commission
will, on its own initiative or on the request of one third of the Member
States, recommend the suspension of negotiations and propose the conditions
for eventual resumption. The Council will decide by qualified majority
on such a recommendation, after having heard the candidate State, whether
to suspend the negotiations and on the conditions for their resumption.
The Member States will act in the IGC in accordance with the Council decision,
without prejudice to the general requirement for unanimity in the IGC.
The European Parliament will be informed.
Parallel to accession negotiations, the Union will engage with every candidate
State in an intensive political and cultural dialogue. With the aim of
enhancing mutual understanding by bringing people together, this inclusive
dialogue also will involve civil society.
