Turkey–Qatar defence pact gives Ankara a second Gulf promise to keep

Turkey and Qatar signed a mutual defence agreement in Istanbul on Friday 13 November. President Recep Tayyip Erdoğan and Qatar’s emir, Sheikh Tamim bin Hamad Al Thani, signed it at the Dolmabahçe presidential office during the 12th meeting of the two countries’ Supreme Strategic Committee, according to Qatar News Agency, Anadolu and the Turkish presidency. Neither government has published the text. The Turkish presidency said only that the pact would “add a new dimension” to relations and that defence-industry cooperation would keep growing. Middle East Eye reported that, unlike earlier Turkish–Qatari defence deals, the new one obliges each country to come to the other’s defence.

Most coverage has treated the signing as a bilateral story: two old allies tightening an existing partnership. The more important point is what it adds to Turkey’s commitments. Ankara now has, or is about to have, two separate promises to defend Gulf states, and one of those states is already at war.

A second Gulf promise in three months

On 7 August Turkey, Saudi Arabia and Pakistan signed the Mecca Joint Defence Agreement, which treats an armed attack on any of them as an attack on all. Turkey’s parliament approved it last week by 279 votes to 119, according to Middle East Eye and the Ilke news agency, and the law approving it was adopted on 5 November, according to the text published by the Grand National Assembly. The 16-article pact has no expiry date and allows withdrawal only after ten years, Middle East Eye reported.

Saudi Arabia is fighting the Houthis in Yemen, who have been striking Saudi oil infrastructure and cities. Turkish officials have said the next step is a separate parliamentary mandate to deploy forces to the kingdom. The foreign minister, Hakan Fidan, has said any deployment would be defensive and that Turkish forces would not operate in Yemen. According to Middle East Eye, Ankara also still needs a status-of-forces agreement setting out which courts would have jurisdiction over its troops.

The Qatar pact sits on top of a much older presence. Under a 2014 agreement, which entered into force in 2017 after Turkey’s parliament approved it, Turkey has had troops at a base in Qatar for years, and its parliament approved a larger deployment in June 2017, days after the Saudi-led blockade of Qatar began. In October this year Turkey, Qatar, Pakistan and Indonesia also signed the “Badr” memorandum in Doha, which covers joint arms production, training and research but, as its signatories describe it, contains no mutual defence commitment.

The result is a set of overlapping obligations with Turkey at the centre. Turkey has a NATO commitment in Europe, a three-way defence pact with Riyadh and Islamabad, and now a bilateral defence pact with Doha. Saudi Arabia and Qatar, meanwhile, were on opposite sides of the 2017 blockade, in which Turkey sided with Qatar. Both are now, separately, under Turkey’s protection.

Who holds the power

For Qatar, the agreement is insurance against doubts about the United States. Qatar hosts Al Udeid, the main US air base in the region, and in September 2025 President Donald Trump signed an executive order saying Washington would treat an armed attack on Qatar as a threat to American peace and security. That order followed Israel’s airstrike on Doha that month. An order is not a treaty, and a security analyst, Yusuf Alabarda, told Al Jazeera on Friday that Gulf states, “especially Qatar”, had concluded that their US security guarantees “are not working properly”. That is his reading, not an official Qatari position, but it explains why Doha wants a second guarantor whose troops are already in the country.

For Turkey, the pacts bring influence and customers. Qatar has money; the Badr memorandum was built on the idea that Turkey supplies technology and Qatar supplies capital, as analysts told Al Jazeera in October. Mr Erdoğan said on Friday that defence-industry cooperation would continue to grow, according to his office. Bilateral trade was only $1.3bn in 2025 against a target of $5bn, according to Türkiye Today. Defence and energy, not ordinary commerce, are what hold the relationship together.

The real limit on all this is Turkey’s own parliament. Approving a defence treaty does not authorise sending troops. Each deployment needs a separate mandate, as the Mecca process shows, and Ankara has so far offered Riyadh air defence and other non-offensive support rather than combat forces, according to analysts writing for the Carnegie Endowment and the Middle East Forum. A promise to defend two Gulf states is only as strong as Turkey’s willingness to fight for them. So far that willingness stops at defence.

The overlooked agreement: mediation, and Africa

One of the four other documents signed on Friday has drawn almost no attention: a memorandum of understanding on cooperation in peace, reconciliation and conflict resolution, signed by Mr Fidan and Qatar’s prime minister and foreign minister, Sheikh Mohammed bin Abdulrahman Al Thani. Its contents have not been published either. But the two signatories are among the most active outside mediators in Africa.

Qatar facilitated the Doha Framework for a Comprehensive Peace Agreement between the Democratic Republic of Congo and the AFC/M23 rebel alliance, signed in Doha on 15 November 2025, and it remains a facilitator of implementation talks alongside the United States, Togo as the African Union mediator, Switzerland and the AU Commission, according to a joint statement published by Qatar’s foreign ministry in August. Turkey brokered the Ankara Declaration of December 2024 between Somalia and Ethiopia over Ethiopia’s port deal with Somaliland, which Qatar publicly welcomed at the time. Turkey’s own statement on Friday said the leaders also discussed Libya, where both countries backed the Tripoli-based government during the 2019–20 war.

A formal mediation partnership between the two could make them a more coordinated diplomatic force in the Horn, the Great Lakes and North Africa. It could also blur the line between mediation and the two countries’ strategic interests, which in Libya have included backing one side. African parties to talks in Doha or Ankara will want to know whether the new memorandum means joint mediation, shared funding, or simply better coordination between two capitals that already work closely. That has not been explained.

What happens next

Three things will show how much the Istanbul pact matters. The first is whether the text is published and sent to Turkey’s parliament for approval, as the Mecca agreement was, and whether it says what counts as an attack and what help each side must give. The second is whether Turkey’s presence in Qatar changes, for example through the air-defence deployments that Mr Alabarda suggested could follow. The third is how Ankara manages two Gulf commitments at once if the US-Iran conflict flares again, since Turkey has said it wants to prevent war in the Gulf, not join one.

For now, the agreement is a statement of intent by two governments that no longer want to depend on a single outside protector. Whether it becomes a real military obligation will be decided in Ankara, not Doha.
