Turkish President Recep Tayyip Erdogan arrived in Saudi Arabia on Friday, August 7, 2026, for a short visit expected to end with a new defence agreement between Turkey, Saudi Arabia, and Pakistan. Reuters reported on August 6 that the three countries were set to sign the joint defence pact in the city of Jeddah, citing sources familiar with the arrangements.

Pakistani Prime Minister Shehbaz Sharif arrived in Saudi Arabia on Thursday, August 6, for a three-day visit, accompanied by Pakistan's army chief Field Marshal Asim Munir. Erdogan was expected to hold a meeting with Mohammed bin Salman and Sharif during the visit. Turkish presidential communications director Burhanettin Duran confirmed Erdogan was expected to meet with both leaders, saying the trip would focus on "bilateral relations and regional developments" without sharing a formal agenda.

The deal would likely build on a mutual-defence agreement that Saudi Arabia and Pakistan signed in September 2025. That treaty treats an attack on one country as an attack on both, meaning each is obligated to help defend the other. Adding Turkey to that framework would link three of the largest armies in the Muslim world. It would also commit Turkey to defending interests in the Gulf and Arabian Peninsula through a formal treaty for the first time.

This is Erdogan's second visit to Saudi Arabia in 2026 and his first since the outbreak of the US-Israel war on Iran. His previous visit to Riyadh in February 2026 brought similar talk of a Turkish-Saudi partnership, but no formal alliance came out of it. During that February stop, Erdogan and Mohammed bin Salman covered bilateral relations and cooperation in energy, defense industry, investments, trade, and technology, according to the Turkish presidency's communications directorate. A joint statement was published following those contacts. On his return flight, Erdogan told journalists he had productive meetings with the Saudi crown prince.

Sharif and Mohammed bin Salman had also met in Jeddah in March 2026 to discuss regional developments, Reuters reported at the time, showing that Riyadh and Islamabad had stayed in regular contact in the months before Friday's expected signing.

The region around the pact has become much more dangerous. Iran retaliated against US and Israeli attacks by launching missiles and drones at military bases hosting American troops across the region, including in Gulf states, and also targeted hotels and energy sites. Saudi Arabia has also been dealing with rising tensions with the Houthis in Yemen, with the two sides trading attacks and the Yemeni group targeting Saudi ships in the Red Sea.

A week before Erdogan's visit, Saudi Arabia unveiled a multinational maritime security initiative to protect shipping through the Red Sea, the Bab al-Mandeb strait, and the Gulf of Aden, backed by 14 countries including Turkey and Pakistan. That initiative and the trilateral defence pact are complementary instruments: one secures sea lanes through multilateral coordination, the other binds three states to mutual defence obligations on land.

The broader context here is that security partnerships across the Middle East and South Asia are shifting rapidly. The US-Israel war on Iran has left Gulf states in a vulnerable position, caught between their American security partnerships and the reality that Iranian missiles can reach them. Riyadh's September 2025 mutual-defence treaty with Islamabad was an early sign that Saudi leadership was looking beyond traditional Western security guarantees. Bringing Turkey into that framework, if the signing goes ahead, would add a NATO member with the second-largest standing army in the alliance to a pact that already links the Gulf and South Asia.

For Ankara, there are benefits and risks. Turkey has sought deeper defence industrial cooperation with Gulf states and has prioritised economic ties with Saudi Arabia, as the February joint statement's emphasis on energy, defense industry, investments, trade, and technology made clear. But formal mutual-defence obligations would tie Turkey to Gulf security situations it has previously handled through informal diplomacy rather than treaty commitments. The February visit produced no formalised alliance; whether Friday's signing completes that transition depends on the final text, which has not been publicly released.

What is still unclear is how a three-way mutual-defence pact would interact with Turkey's existing NATO obligations, and whether the agreement includes the same automatic-response trigger that characterises the Saudi-Pakistani treaty. The Turkish intelligence source's claim that basic terms were already agreed suggests the negotiations have moved beyond early drafting, but the specifics of what each side has committed to will only become clear once the agreement is signed and, if it is, published.
