Pakistan has dispatched approximately 8,000 troops, a squadron of Chinese-made JF-17 fighter jets, two drone squadrons, and an HQ-9 surface-to-air missile defence system to Saudi Arabia under a mutual defence pact signed last year. The full scale of the deployment, confirmed by three security officials and two government sources, has been disclosed for the first time. Described as a substantial, combat-ready force, it is intended to bolster the Saudi military should the kingdom face further attack. Neither the Pakistani military nor the foreign ministry, nor the Saudi government media office, responded to requests for comment on the equipment and troop numbers, underscoring the sensitivity of the arrangement.

The deployment raises acute questions about Pakistan’s simultaneous role as the principal mediator in efforts to end the US-Iran standoff. From Islamabad’s perspective, the move reflects a balancing act between its longstanding alliance with Riyadh and its diplomatic ambitions. Yet viewed from Tehran, the positioning of thousands of troops and advanced Chinese weaponry on its southern flank risks undermining Pakistan’s claims of neutrality. Analysts in London note that the contradiction could erode trust in Pakistan’s mediation at a moment when the region is on edge, particularly after recent informal exchanges of fire between Iran, the UAE, and Saudi Arabia.

The diplomatic backdrop is further complicated by President Donald Trump’s latest stance. In a brief interview with the New York Post, Trump said he received Tehran’s recent response to negotiations and declared he has “no intention” of granting any concessions to the Islamic Republic, warning that “it will soon find out what happens.” Republican Senator Lindsey Graham reinforced that message, expressing confidence that Trump will not appease Iran over its refusal to negotiate in good faith and its actions in the Strait of Hormuz. Graham urged that any talks be conducted from a position of strength with a decisive response.

Looking ahead, the deployment is more than a military signal; it is a test of Pakistan’s ability to manage contradictory pressures. The secret nature of the mutual defence pact leaves neighbours and international partners guessing about its precise commitments. As Washington and Tehran remain deadlocked, and with Riyadh bolstering its defences, Pakistan’s effort to straddle both camps may become untenable. The coming weeks will reveal whether Islamabad can sustain its mediating role while deepening a military alliance that increasingly looks like an implicit alignment against Iran.
