“Syria, on the basis of the principle of reciprocity, will not allow activities that depart from its territory and are supposed to jeopardize Turkey`s security and stability. Syria will not allow the supply of PKK weapons, logistical equipment, financial support and propaganda activities on its territory,” an article in the agreement said. The agreement confirmed a new model of friendly relations with Syria — and Iran surged in 2003 and concluded that Turkey`s agreement should be part of its broader regional strategy. This change was a response to the American invasion of Iraq, which led Tehran to decide that it should reach its neighbor, Turkey, to counter the threat of the United States encircling Iran. Tehran severed relations with the PKK when U.S. troops landed in Iraq. At first, Syria rejected the Turkish demands, but after important negotiations it decided to partially accept the end of the PKK`s presence in Syria. Prior to the agreement, the Syrian government allowed Ocalan to leave the country instead of handing it over to the Turkish authorities, as required by Turkish request. Instead, he was put on a plane to Moscow.   “The 1998 Adana Agreement was concluded between Turkey and Syria, its essence is to allay Turkey`s fears for its security,” Lavrov said. “This agreement paves the way for Turkey to enter in the event of adverse events,” President Recep Tayyip Erdogan said, two days after meeting with Russian President Vladimir Putin at a rally in the eastern province of Erzurum, reaffirming his willingness to fully implement the agreement. The Syrian regime “has concluded this agreement and has accepted certain commitments, and we assume that this agreement will remain in force. As far as I know, the States Parties are doing the same,” he added.
At a press conference in Rabat after a meeting with his Moroccan counterpart Nasser Bourita, Lavrov said how the Adana agreement was still in force and argued that it could serve as a basis for negotiating related issues. 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 5 km of depth in Syrian territory.
