Saudi Arabia has entered a NATO-like Islamic alliance with Pakistan, which has nuclear weapons, and is part of a group of friends of China.

Judge as of 2025-09-19. The claim has three parts: (a) Saudi Arabia has entered a formal alliance with Pakistan that is 'NATO-like', meaning it contains a mutual-defence commitment under which aggression against one counts as aggression against both; (b) Pakistan has nuclear weapons; (c) Saudi Arabia is part of a grouping or circle of states friendly to China. 'Islamic alliance' is met if the pact is between Muslim-majority states (bilateral counts). True: a Saudi–Pakistan agreement with such a mutual-defence clause was signed on or before 2025-09-19, Pakistan is a nuclear-armed state, and Saudi Arabia has formal or widely recognised close ties with China (for example SCO dialogue partner status, a BRICS invitation or membership, or a comprehensive strategic partnership). Mostly true: (a) and (b) hold but (c) holds only loosely, for example close ties with China but no membership of any China-led grouping. Mixed: the agreement exists but is only a cooperation or consultation pact with no mutual-defence commitment, so 'NATO-like' is a substantial overstatement, while the other parts hold. Mostly false: there is only an announced intention or a draft, with no signed agreement by that date. False: no such Saudi–Pakistan defence agreement exists, or Pakistan does not have nuclear weapons.

   “Pakistan and Saudi Arabia have entered into a landmark mutual defence agreement, under which any aggression against one state will be considered an attack on both.”

4. E4 Could the Pakistani-Saudi Defense Pact Be the First Step Toward a NATO-Style Alliance? - Nuclear Network Nuclear Network (CSIS) · 6 October 2025

   “While the pact’s NATO-like language signals an intent to strengthen collective deterrence, the SMDA currently lacks the necessary provisions for nuclear deterrence and regional political consensus to evolve into a joint defense framework.”

The evidence shows that a Saudi–Pakistan mutual defence agreement with an aggression-against-one clause was signed on 17 September 2025 [E1][E2], and that Pakistan has nuclear weapons [E3]. No evidence item covers Saudi Arabia's ties to China, so the material cannot settle part (c), which the criteria use to tell true from mostly true.
