Prije pokretanja svojih pregovora o pristupanju, Turska je potpisala dogovor kojim se njen carinski sporazum sa EU proširuje na sve njene nove članice, uključujući i Kipar, koji su se bloku pridružio u maju 2004, ali bez svog sjevernog dijela pod Turcima, koji priznaje samo Ankara.
Prior to the launch of its accession talks, Turkey signed a deal extending its customs agreement with the EU to all its new members, including Cyprus, which joined the bloc in May 2004, minus its Turkish-run north, which is recognised by Ankara alone.
