The main objective of the agreement was to restore bilateral relations between Syria and Turkey, although the Turkish delegation insisted that full normalization should not be achieved until Syria met the requirements, including the cessation of what Turkey considered to be an “incitement to other Arab League member nations against Turkey” , as well as cooperation in the arrest of Ocalan. These requirements were attached to the text of the agreement.  The agreement signed in the southern city of Adana in Turkey was aimed at allaying Ankara`s fears about the presence of the PKK terrorist group in Syria. During its decades of campaigning of terror, the PKK has killed 40,000 people in Turkey, including women, children and young children. It is also considered a terrorist organization by Turkey, the United States and the European Union. The text of the agreement, which is publicly available, does not provide for any provision allowing Turkey to travel five kilometres deep into Syria. Turkish politicians and experts say the law stems from a secret provision that both sides have hidden from the public. The only relevant document that has emerged to date is a letter of 22 October 1998 sent by the Turkish Foreign Minister, Mr Ismail Cem, to the President of the European Commission to provide him with information on the agreement. The letter, the copy of which was seen by the journalist, cites an “annex 4” of the agreement that “the Syrian side understands that its inability to take the necessary measures and security obligations set out in this agreement gives Turkey the right to take all necessary security measures within a 5 km deep period on Syrian territory.” The Adana Agreement (pronounced [a da.na]; in Turkish: Adana Mutabakat; In Arabic: “) was a 1998 agreement between Turkey and Syria on the expulsion of the Kurdistan Workers` Party (PKK) from Syria.  The agreement was updated in 2010, a year before the start of the war in Syria, and the Turkish Parliament approved it in 2011.
Turkey and Syria will lead broader cooperation in the fight against terrorism. However, another formal document exists between the two countries: the Joint Cooperation Agreement on Counter-Terrorism and Terrorist Organizations, signed on 21 December 2010 by Turkish Foreign Minister Ahmet Davutoglu and his Syrian counterpart Walid Muallem, in support of the Adana Agreement. The 23-article agreement came into force on 26 April 2011, after approval by the government and Parliament, replacing the Adana agreement. The agreement had a three-year validity period, which was automatically renewed, unless both sides withdrew, but with the outbreak of the Syrian conflict, it became irrelevant. In addition, Turkey`s border policy has allowed the passage of weapons and militants into Syria and has encouraged the insurgency.
