The Adana agreement between Turkey and Syria was concluded on 20 October 1998 in the Turkish city of Adana and contained the following: In 1998, Damascus signed a protocol with Ankara in the southern Turkish city of Adana, promising to stop supporting the PKK. Iran joined this consensus in 2003 and Syrian and Iranian support for the PKK is once again in the spotlight, with the disintegration of Syria and Turkish-Iranian competition destroying the foundations of the old status quo. In light of the messages sent by the President of the Arab Republic of Egypt, H.E.Mr Hosni Mubarak and Iranian Foreign Minister H.E.Mr. Kamal Kharrazi, on behalf of Iranian President H.E.Mr. Seyid Mohammed Khatemi and the Minister of Foreign Affairs of the Arab Republic of Egypt H.E., the Turkish and Syrian delegations whose names are on the attached list (Annex 1) met in Adana on 19 and 20 October 1998 to discuss the issue of cooperation in the fight against terrorism. 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 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, signed by Turkey and Syria on 20 October 1998, was the most critical topic on the agenda of the meeting between Turkish President Recep Tayyip Erdogan and Russian President Vladimir Putin on 23 January. The two heads of state and government discussed the agreement at their joint press conference. Putin stressed that the 20-year-old agreement between Ankara and Damascus remained binding, while Erdogan stressed its importance and said Turkey would keep it on its agenda.
It was the first meeting between the two heads of state since the announcement of the U.S. decision to withdraw its troops from Syria. That is why their discussions were already important – and the issue of the Adana agreement became even more important. What is this 1998 agreement and why is it back on the agenda after seven years of conflict in Syria? The Adana agreement was signed at a time when relations between Turkey and Syria were tense and neighbours were on the brink of war. Damascus had allowed Abdullah Ocalan, leader of the Kurdistan Workers` Party (PKK), who is now serving a life sentence on the Turkish island of Imrali, to protect and direct the terrorist organization`s activities for several years within its borders. When Turkey threatened to act militarily, Damascus deported Ocalan and closed PKK camps in the country. The Adana agreement should help restore bilateral relations. It was finally concluded after Iranian Foreign Minister Kemal Harrazi and Egyptian Foreign Minister Amr Moussa intervened on behalf of their presidents. Some have described the agreement as a Turkish-Syrian version of the Camp David agreement signed by Egypt and Israel. In 1998, Syria and Turkey signed an agreement in turkey`s southern city of Adana to allay Ankara`s fears about the terrorist group PKK. In 1998, Syria and Turkey signed a pact with which Damascus actively worked to allay Turkey`s concerns about the terrorist PKK.
