Within NATO, the process of enlargement normally involves the following steps1:

  • Allies invite an aspirant to begin accession talks.
  • Accession talks with a NATO team.

The aim of these talks is to obtain formal confirmation from the invitees of their willingness and ability to meet the political, legal and military obligations and commitments of NATO membership, as laid out in the Washington Treaty and in the 1995 Study on NATO Enlargement.

  • Invitees send letters of intent to NATO, along with timetables for completion of reforms.

In the second step of the accession process, each invitee country provides confirmation of its acceptance of the obligations and commitments of membership in the form of a letter of intent from each foreign minister addressed to the NATO Secretary General. Together with this letter, they also formally submit their individual reform timetables.

  • Accession protocols are signed by NATO countries.

NATO then prepares Accession Protocols to the Washington Treaty for each invitee. These protocols are in effect amendments or additions to the Treaty, which once signed and ratified by Allies, become an integral part of the Treaty itself and permit the invited countries to become parties to the Treaty. From the moment when Accession Protocols are signed, NATO invites representatives of the invited countries to attend meetings of the North Atlantic Council as observers.

  • Accession Protocols are ratified by NATO countries.

The governments of NATO member states ratify the protocols, according to their national requirements and procedures.
