Can Russia Revive the Adana Agreement between Syria and Turkey?

Whenever Turkey threatens to launch a military operation in northern Syria to establish a “safe zone,” Russia puts on the mediation table the revival of the Sochi Agreement on the east of the Euphrates, in preparation for the implementation of the Adana Agreement. The latter was signed by Ankara and Damascus in July 1998, establishing security cooperation between the two parties and allowing the Turkish army to pursue the Kurdistan Workers Party (PKK) deep into Syrian territory.

Since the Russian war in Ukraine, Turkish President Recep Tayyip Erdogan has activated his old plan to establish a safe zone with a depth of 35 kilometers, trying to benefit from the improvement of Ankara’s negotiating position due to Washington and Moscow’s “need” for Turkey’s role.

America clearly announced its rejection of the military operation east of the Euphrates, while Moscow mediated between Damascus, Ankara and the Kurds, and deployed Syrian army forces in various areas in the north of the country to “deter” the Turkish army, ahead of the Russian-Turkish-Iranian summit in Tehran on Tuesday.

Ankara wants new incursions linking its military “enclaves” in northern Syria, namely the Euphrates Shield, north of Aleppo, which was established in 2016, the Olive Branch in Afrin in 2018, the Peace Spring, eEast of the Euphrates, formed at the end of 2019, and the Peace Shield, at the start of 2020.

Moscow proposes either activating the Adana Agreement or the full implementation of the Sochi Agreement of 2019, in addition to a military memorandum between Damascus and Qamishli in exchange for an agreement between Ankara and Washington. Below is a review of the most important agreements:

What are the terms of the Adana Agreement?

After Turkey threatened to attack Syria in mid-1998, late Egyptian President Hosni Mubarak mediated between the two parties, until a security agreement was concluded between Ankara and Damascus in the Turkish city of Adana. The text of the agreement and its annexes included, among others, the following items:

- As of now, the leader of the Kurdistan Workers’ Party, Abdullah Ocalan (detained in Turkey since the beginning of 1999), will not be in Syria, and will certainly not be allowed to enter Syria.
- PKK members abroad will not be allowed to enter Syria.
- As of now, PKK camps will not operate on Syrian soil, and will certainly not be allowed to become active.
- Many members of the PKK were arrested and referred to the court. The lists containing their names were prepared and submitted by Syria to the Turkish side.
- Syria, based on the principle of reciprocity, will not allow any activity launched from its territory that harms the security and stability of Turkey. Nor will Syria allow the supply of weapons, logistical materials, and financial and promotional support for PKK activities on its soil.
- Syria has classified the PKK as a terrorist organization, and has banned the activities of the party and its affiliated organizations on its territory, along with other terrorist organizations.
- Syria will not allow the PKK to establish camps or other facilities for training and shelter purposes or to conduct commercial activities on its soil.
- Syria will not allow members of the Kurdistan Workers Party to use its territory to cross to third countries.
- A direct telephone line is immediately operated between the higher security authorities of the two countries.
- The two parties appoint special security representatives in their diplomatic missions in Ankara and Damascus. Those are presented to the authorities of the host country by the heads of the mission.
- Annex No.3: As of now, the two parties consider that the border disputes between them have ended, and that neither of them has any claims or rights due in the territory of the other party.
- Annex No. 4: The Syrian side understands that its failure to adopt the security measures and duties stipulated in this agreement gives Turkey the right to implement all necessary security measures inside Syrian territory to a depth of five kilometers.

What does the Adana Agreement mean at the political and security levels?

• It gives the Turkish army the right to pursue the PKK at a depth of five km in northern Syria, according to Annex No. 4.
• Damascus relinquishes any claim to its rights in Iskenderun (Hatay Province), which Turkey annexed in 1939, according to Annex No. 3.
• The PKK, led by Abdullah Ocalan, is considered a “terrorist organization”, in accordance with the provisions of the agreement.
• Ankara interprets the agreement as meaning that the Kurdish People’s Protection Units (YPG) is a “terrorist organization”, as an extension of the PKK.
• The agreement means the start of direct security contacts, knowing that the Director of Syrian National Security, Ali Mamlouk, has held several meetings with Turkish Intelligence chief Hakan Fidan.
• It also means re-operating the Turkish embassy in Damascus and the Syrian embassy in Ankara, noting that Damascus has a consulate in Istanbul, given that the agreement requires the appointment of a security liaison officer in each embassy.
• The agreement entails “indirect contacts” acknowledged by Turkish Foreign Minister Mevlut Cavusoglu, and Ankara’s recognition of the legitimacy of the Syrian government, as its required many procedures, including the formation of a joint committee and the operation of a hotline.
• The agreement offers an alternative to the Turkish-American understanding on the depth of the “buffer zone” of 32 kilometers in northeastern Syria, and opens the way for the implementation of the Sochi Agreement between Erdogan and President Vladimir Putin in October 2019, following former US President Donald Trump’s decision to withdraw his forces from the east of the Euphrates, which paved the way for a Turkish attack at the time.

What is the 2019 Sochi Agreement?

Erdogan and Putin have agreed on 10 points, including:

The determination to combat terrorism in all its forms and manifestations, and to disrupt separatist projects in Syrian territory.
• In this context, the status quo will be preserved in the current Operation Peace Spring area, which covers Tel Abyad and Ras al-Ain, at a depth of 32 kilometers.
• Both parties reaffirmed the importance of the Adana Agreement. Russia, for its part, will facilitate the implementation of this agreement under the current circumstances.
• The Russian military police and Syrian border guards will enter the Syrian side of the Syrian-Turkish border, outside the area of Operation Peace Spring, in order to facilitate the removal of the Kurdish People’s Protection Units and their weapons.
• Turkey and Russia will conduct joint patrols west and east of the Operation Peace Spring area, at a depth of 10 km, with the exception of the city of Qamishli.
• All members of the Kurdish People’s Protection Units and their weapons will be removed from Manbij and Tal Rifaat.

What about the US-Turkish agreement of 2019?

Prior to that, an agreement was signed between Erdogan and former US Vice President Mike Pence in October 2019, which consisted 13 items. Those included, among others:
• The United States and Turkey confirm their relationship as NATO partners, and the United States understands Turkey’s legitimate security concerns on its southern border.
• The two sides agreed on the need to maintain the safety of the area, in order to address Turkey’s national security concerns and seize heavy weapons from the Kurdish People’s Protection Units.
• The Turkish side temporarily stops Operation Peace Spring to allow the withdrawal of the People’s Protection Units from the Spring area. Operation Peace Spring will be halted upon completion of this withdrawal.
• Once Operation Peace Spring is stopped, the United States agrees not to continue imposing sanctions pursuant to the October 14, 2019 Executive Order banning property and suspending entry to certain persons contributing to the situation in Syria.

How did the Syrian army return to the east of the Euphrates?

In parallel with these Russian-Turkish-American agreements that followed Trump’s withdrawal from Turkey’s borders in northeastern Syria - which opened the way for Ankara’s incursion – a memorandum of understanding was reached between the Syrian Democratic Forces, the allies of Washington, and Damascus. Here are some of its points:

• The Syrian Democratic Forces (SDF), which includes the Kurdish People’s Protection Units, agreed to enter the Syrian Arab Army and extend its control over the entire region, starting from Ain Diwar in the east, and up to Jarablus in the west, where the forces will be deployed from three axes:
1. Tabqa axis in the north towards Ain Issa and its countryside, and in the north, towards the Syrian-Turkish border at Tal Abyad and towards the west.
2. The Manbij axis towards Ain al-Arab on the Syrian-Turkish border, to the point of Tal Abyad and towards the west.
3. Al-Hasakah-Tal Tamer axis to Ras al-Ain and from it to the east to Qamishli and then to al-Malikiyah and towards the south.
4. The forces are deployed in the Manbij area, starting from Arima and along the Sajour River line, according to the previous agreement on the deployment of forces in Arima.

In this memorandum, “the (SDF) forces affirmed their readiness to preserve the unity and territorial integrity of the Syrian Arab Republic and under the flag of the Syrian Arab Republic, and to stand by the Syrian Arab Army in the face of Turkish threats to the Syrian territories, led by President Bashar al-Assad.”

However, Trump’s keeping his forces east of the Euphrates has led to the slow implementation of this memorandum. In the face of recent Turkish threats, Russia returned to push the SDF and Damascus to implement the 2019 memorandum.

Just as Russia implemented the “disengagement” agreement between Syria and Israel and deployed international forces in the Golan, it seeks to put the interim agreements into effect, leading to the reactivation of the Adana Agreement, which would pave the way for “legitimizing” the government and expanding its sovereignty in the country.

Russia had previously suggested this option during the preparations for the tripartite summit in Tehran, and will continue to push for its implementation.

Gemayel to Asharq Al-Awsat: Khaddam was Assad’s Stick to Apply Pressure

Late Syrian President Hafez al-Assad was a masterful negotiator, fiercely protective of his image and reputation. He was known for exhausting his guests with lengthy detours into history before addressing the substance of any talks.

Assad had an exceptional ability to restrain his anger, circling around an issue before striking again — often with calculated patience.

He avoided coarse language, allowing resentments to speak for themselves, but he never forgave those he believed had tried to derail his vision. Among them, according to accounts, were Yasser Arafat, Kamal Jumblatt, Bashir Gemayel, Amine Gemayel, and Samir Geagea.

In dealing with rivals and pressuring opponents, Assad often relied on a trusted enforcer: Abdel Halim Khaddam, his long-time foreign minister and later vice president. In the second part of his interview with Asharq Al-Awsat, former Lebanese President Amine Gemayel said Khaddam was Assad’s “stick,” used to assert control.

Many Lebanese politicians believed Khaddam’s bluntness was not personal, but rather a reflection of an official mandate from his mentor.

Assad rarely issued direct threats. Instead, he preferred subtle intimidation — as when he told Gemayel that his aides had once suggested blowing up President Anwar Sadat’s plane to prevent him from reaching Jerusalem.

Khaddam, the late Syrian strongman’s long-serving envoy, was known for humiliating both allies and foes who dared defy Damascus’ directives. His tactics were often unsettling — deliberately designed to leave visitors unnerved and pliant by the time they reached Assad’s office.

In a conversation in Paris during his retirement, Khaddam defended his hardline methods, saying they were not meant to insult but to prevent potentially dangerous confrontations. “The aim was to avoid escalation that could lead to security agencies taking over, which might have resulted in worse outcomes,” he said.

In the same meeting, Khaddam accused former Lebanese President Amine Gemayel of obstructing a political solution in Lebanon, calling him “hesitant and suspicious.”

He also acknowledged Assad was caught off guard when the Tripartite Agreement collapsed. The Syrian leader, Khaddam said, had not believed anyone in Lebanon would openly defy Syria — or the other Lebanese factions who had signed the accord.

“President Assad had many cards to play. President Sarkis had none,” recalled former Lebanese Foreign Minister Fouad Boutros, reflecting on the stark imbalance between Syria and Lebanon during Elias Sarkis’s presidency.

Assad, he said, had the power to topple or paralyze the Lebanese government before Sarkis even returned to Beirut. “Sarkis had no leverage over Assad,” Boutros noted. “But while Sarkis often showed flexibility, he would stand firm when asked to compromise Lebanon’s core principles.”

Boutros, who played a key role in Lebanon’s diplomacy during the civil war, said he had to exercise utmost restraint to keep Khaddam — Syria’s often abrasive envoy — from derailing talks with personal attacks or inflammatory language.

The dynamic, he suggested, was not unique to Sarkis. It also echoed the later, uneasy relationship between Gemayel and Assad.

Gemayel recalled a cold and confrontational relationship with Khaddam, describing him as “the stick and the poison” used by Assad to pressure Beirut into submission.

“There was no warmth between us from the beginning,” Gemayel told Asharq Al-Awsat.

“Khaddam used underhanded tactics to undermine the presidency and sow division within my team. While President Assad treated me with respect and politeness, he needed someone to apply pressure — and that was Khaddam,” he added.

Gemayel said Khaddam was behind all the pressure campaigns Syria waged against him — all with Assad’s full knowledge. “Assad played the courteous statesman. Khaddam handled the dirty work. Syria wanted me to sign agreements harmful to Lebanon’s interests, and Khaddam was the one tasked with forcing my hand.”

Despite Khaddam’s harsh demeanor, Gemayel said he never allowed him to overstep.

“I kept him in check. He didn’t dare cross the line with me. We were once in a meeting with President Assad, and Khaddam had been spreading ridiculous rumors beforehand. When he spoke up, I turned to Assad and said: ‘Mr. President, we have a problem with Khaddam. Please ask him to stop acting like a spy when dealing with us.’”

Khaddam, Gemayel said, tried to intimidate many Lebanese politicians — but not him.

“He was rude, even insolent to the point of absurdity. But he knew that if he said anything out of line with me, I would respond immediately.”

Assad’s Subtle Control and the Language of Minorities

Assad understood early on the fragility of Lebanon’s sectarian makeup. To him, the country was a meeting place for minorities — one that always needed an external patron to manage its wars and truces. He allowed for limited victories, but never total defeat, ensuring that no side could do without Syria’s oversight.

Assad sought to rule Syria indefinitely, with Lebanon as a backyard extension of his regime. Yet unlike his brother Rifaat, he avoided openly sectarian rhetoric or calls for partition. Rifaat, according to Gemayel, once suggested dividing both Syria and Lebanon along sectarian lines during a conversation with Lebanese leaders Walid Jumblatt and Marwan Hamadeh.

When asked whether he ever felt his dialogue with Assad was, at its core, a conversation between an Alawite and a Maronite, Gemayel replied: “No — that was Rifaat’s language. He used to say minorities must come together and show solidarity. But that narrative was never pushed by President Assad or his inner circle. It was always tailored to serve their own agenda.”

Assad’s political strategy was built on gathering leverage — and minority groups were central to that plan. His ties with Lebanon’s Druze community, and his clash with Druze leader Kamal Jumblatt, fit squarely within this framework. Assad relied on Syria’s own Druze population, as well as the Christian minority, to tighten his grip on the country’s diverse communities and align them under the banner of his regime.

“Assad had a firm hold on the minorities,” Gemayel said, adding that “he brought them all together to make them part of the Syrian system.”

Tensions between Syria’s Alawite leadership and the country’s Sunni majority were well known, Gemayel added, particularly through the candid rhetoric of Assad’s brother, Rifaat.

“Rifaat was open about the hostility between Alawites and Sunnis,” Gemayel said. “In his conversations with us, it was clear. But with President Assad, there was no visible sign of that. What lay beneath the surface, only God knows — but in our dealings with him, we never felt it.”

Gemayel Dismisses Reports of a Syria-Lebanon Confederation Proposal

Asked about longstanding claims that former Lebanese President Camille Chamoun had once proposed a confederation between Lebanon and Syria to Hafez al-Assad, Gemayel was quick to reject the idea.

“That’s absolutely not true,” he said. “President Chamoun would never have made such a proposal. A lot of things were said at the time. There were even reports that US envoy Dean Brown had suggested relocating Lebanon’s Christians to California — all of it nonsense, poetic talk with no grounding in reality.”

Gemayel also addressed one of the most controversial moments in US diplomacy during Lebanon’s 1988 presidential crisis: the phrase reportedly used by US envoy Richard Murphy — “Mikhael Daher or chaos.”

Daher, a Christian MP close to Damascus, had been floated as the only candidate acceptable to both Syria and the United States.

But Washington later distanced itself from the deal. The episode, Gemayel said, underscored a period in which American pressure aligned more with Syrian — and by extension, Israeli — interests, leaving Lebanon’s sovereignty hanging in the balance.

Gemayel confirmed that US envoy Richard Murphy did indeed issue the stark ultimatum in 1988. The phrase, which became emblematic of foreign interference in Lebanon’s presidential crisis, reflected what Gemayel described as Washington’s unwillingness to confront Damascus — despite acknowledging its destabilizing role in Lebanon.

“Yes, Murphy said it,” Gemayel affirmed to Asharq Al-Awsat.

“The Americans had a problem — they wanted Syria, and they didn’t. They knew Syria was playing a destructive role in Lebanon, but they didn’t want to challenge it. They kept trying to find common ground with Syria, not with us.”

According to Gemayel, the US saw Daher — a respected Christian parliamentarian close to Damascus — as a palatable compromise. “They thought Daher was a respectable figure who might be acceptable to the Lebanese, so they went along with Syria’s choice,” he said.

Washington, he added, had consistently prioritized pragmatism over principle in Lebanon, often aligning with whichever side could deliver results — even if it came at Beirut’s expense.

“It was the same with the May 17 Agreement with Israel,” Gemayel said, referring to the short-lived 1983 accord.

“The US couldn't pressure Israel, so Lebanon had to pay. And they couldn’t pressure Syria either — Syria was stubborn, had resources, and they didn’t want a confrontation. So they kept trying to sell us solutions that weren’t in Lebanon’s interest.”

“The Americans were always looking for the quickest deal,” he added. “They wanted to please both Syria and Israel. With Syria, it was clear — they didn’t want to upset Assad, because they knew who held the real power in Lebanon.”

Gemayel said that while he personally held the reins in decision-making and negotiations with Syria during his time in office, several close advisers and intermediaries played essential roles in laying the groundwork for dialogue with Damascus.

“The relationship and final decisions were in my hands,” he told Asharq Al-Awsat.

“I was the one doing the actual negotiating. But when it came to preparation, the late Jean Obeid played a very valuable role. He was intelligent, committed to Lebanon’s interests, and had close ties with the Syrians. He couldn’t get everything done, but he managed to ease certain issues,” said Gemayel.

Gemayel also credited Eli Salem, another aide, for navigating delicate talks with Syrian officials — particularly with Khaddam.

“Salem had a knack for getting through on specific points,” Gemayel said. “He had good chemistry with Khaddam, and that helped, especially since Khaddam and I didn’t get along.”

One figure who unexpectedly played a constructive role, according to Gemayel, was Brigadier General Jamil al-Sayyed, then an intelligence officer stationed in Lebanon’s eastern Bekaa Valley.

“You may be surprised,” he said, “but Jamil al-Sayyed was very helpful. Whenever I was heading to Damascus, I would stop in the Bekaa to meet him. He gave me very precise insights into what was happening at the Syrian presidential palace and the broader picture in Damascus. He was well-informed, sincere, and provided intelligence that wasn’t widely available — information that truly benefited Lebanon.”

Asked whether Syria was uneasy about the role of veteran journalist and diplomat Ghassan Tueni in his administration, Gemayel said the Syrians had little affection for him.

“There was never any warmth toward Ghassan,” he said. “He came with me to Syria just once, and it was clear there was tension. Whenever he was present, things got heated. Ghassan and Khaddam were like a ping-pong match — constantly hitting the ball back and forth.”

The friction, Gemayel explained, stemmed in large part from Tueni’s association with An-Nahar, the Beirut daily he helped lead, which often published sharp criticism of Syria.

“Syria never appreciated An-Nahar,” Gemayel said. “Even if Ghassan tried to distance himself from specific articles, the content was out there for everyone to see — and the Syrians didn’t forget it.”
