Saudi Crown Prince Mohammed bin Salman, Turkish President Recep Tayyip Erdogan and Pakistani Prime Minister Shehbaz Sharif signed a collective‑defence treaty on August 7, creating a three‑nation security bloc. The agreement, announced amid escalating U.S.–Iran tensions, obligates the parties to treat any armed attack on one as an attack on all, marking the most formalized defence coordination among major Sunni powers to date.
The Mecca Joint Defence Agreement was signed in Jeddah by Crown Prince Mohammed bin Salman, President Erdogan and Prime Minister Sharif, with Turkey’s foreign minister Hakan Fidan and Pakistan’s foreign minister Ishaq Dar later emphasizing that the pact is purely defensive and not aimed at any specific country, including Iran. It also invites other regional states to join under the same collective‑defence terms.
The alliance links Saudi Arabia’s oil wealth and regional clout, Turkey’s NATO membership and growing defence industry, and Pakistan’s nuclear arsenal and extensive combat experience, potentially reshaping procurement and security spending across the Gulf and South Asia. Existing Saudi‑Pakistan defence accords remain in force, and the new framework may influence investors monitoring stability and arms‑sale flows in the region.
