Finally, it is not easy to protect the militants of the People`s Protection Units (YPG) and to tackle Turkey`s security problems. Ankara says it can impose the area without terrorism itself. Although the Turks are opposed to a northern-style solution in Iraq, they seem open to cooperation with the United States, Russia and France. In 1998, Syria and Turkey signed a pact with which Damascus actively worked to allay Turkey`s concerns about the terrorist PKK. Putin`s goal is to encourage Turkey to cooperate with the Syrian regime. After the withdrawal of the United States, he wants Bashar Assad to take control of all areas controlled by the YPG. At the same time, the Russian leader referred to the Adana agreement to ensure that the security zone focuses on border security. Finally, he sent a message to YPG fighters and encouraged them to maintain dialogue with the regime. On 20 October 1998, Turkey and Syria signed the Adana Agreement, which met all of Turkey`s main demands, including serious action against PKK bases in Syria and the expulsion of PKK fighters and leaders.
Within a year, the complete rapprochement was in full swing. Turkish President Ahmet Necdet Sezer surprised everyone by leading his country`s delegation to the funeral of Hafiz al-Asad in June 2000; and in November of that year, Syrian President Bashar al-Asad sent Vice President Abd al-Halim Khaddam to Ankara in a letter pledging to „make a new leaf“ in bilateral relations. For both technical and geopolitical reasons, it is likely that the Turkish armed forces will continue their security cooperation with Israel; Joint military exercises, information exchange and strategic coordination continue on a regular basis. 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. The Adana agreement lasted until 2011, when Turkish support for the Syrian opposition in the context of the civil war ended goodwill between the two countries and the Syrian government again began to support Kurdish groups to counterbalance Turkish efforts in Syria.  The Syrian government said that Turkey had violated the understanding of the agreement by arming rebel groups inside Syria.  In 2012, Turkish officials accused the Syrian government of directly supporting the PKK.  The Adana Agreement between Turkey and Syria was concluded on 20 October 1998 in the Turkish city of Adana and contained the following points:  Since October 1998, Turkey has moved from the brink of war with Syria to the brink of signing a military cooperation agreement: Syrian Chief of Staff Hassan al-Turkomani will officially visit Turkey on 19 June. , the first visit of a Syrian Chief of Staff. Changes in relations between Turkey and Syria illustrate the volatility of Turkey`s general policy in the Middle East over the past decade. „The 1998 Adana agreement was concluded between Turkey and Syria, its essence is to dispel Turkey`s security concerns,“ Lavrov said.
He stressed, however, that the agreement must continue to be respected and that its implementation meant that either the Assad regime would no longer have to operate the YPG in Syria or Ankara would clean up its borders in the neighbouring country, citing the terrorist organization`s threat to national security. In 2019, the agreement gained new significance thanks to ongoing Turkish operations on Syrian territory.   The agreement was specifically mentioned in the second agreement on the North Syria buffer zone. One of the articles of the agreement also deals with close security coordination between the two countries with regard to the PKK. „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 WEAPONs, logistical equipment, financial support and propaganda activities of the PKK on its territory,“ says an article by the
