The three countries have signed a landmark joint defence deal in Mecca that would establish a trilateral security arrangement in which an attack on one of them by another country would be considered an attack against all.
The deal was signed in a meeting at the level of Saudi Crown Prince Mohammed bin Salman with Turkish President Recep Tayyip Erdoğan and Pakistani Prime Minister Shehbaz Sharif.

The agreement's most crucial fact is its mutual defence clause that makes an armed attack against any one of the three signatories an attack against all. Governments haven't released the full operational nature of the treaty yet, but the agreement is similar to the collective defence principle of other military alliances that commit the three countries to closer cooperation if external foes attack.
The agreement will also link cooperation on joint military exercises, intelligence sharing, defence technology sharing, training and strategic coordination (in addition to collective defence). The partnership will enhance deterrence and strengthen the three countries' capacity to respond to regional security challenges, officials in the deal said.
The agreement comes at a time of increasing instability in the Middle East -- on Iran, maritime security, and bigger regional problems. Analysts say the three countries are trying to work better together as uncertainty about regional security and traditional defence structures takes hold.
The agreement also builds on an earlier Strategic Mutual Defence Agreement signed between Saudi Arabia and Pakistan in 2025 and a bilateral mutual defence commitment already in place. Turkey’s inclusion turns that deal into a trilateral security partnership with a broader strategic direction.
In the partnership, all three countries have major military capabilities. Turkey has one of NATO’s largest armies and the fastest-growing defence manufacturing industry. Saudi Arabia has substantial financial resources and strategic influence in the Gulf, while Pakistan has one of the world’s largest armed forces and extensive military experience.
Experts believe the agreement will change regional security by establishing a more coordinated defence framework in which all three countries are participating as one. Some analysts also believe that the pact might eventually be open to others in the region - although no official announcement of this has been made.
The Mecca Joint Defence Agreement is a diplomatic and strategic milestone for Turkey, Saudi Arabia and Pakistan. We will monitor how the new alliance will affect military cooperation, regional security and the geopolitical situation of the Middle East as more details of the strategy are known.
