In close combat JF-17 lacks what it takes to win the fight. Its wings doesn’t have wing twist nor does it have enough area to provide a low wing loading. Its performance during low speeds and high alphas would be very dangerous for the pilot indeed. It has a Maximum G loading of only 8, as claimed by PAC. Its thrust to weight ratio is another negative point. Pakistan Aeronautical Complex(PAC) proudly displays the RD-93’s “Combat thrust with afterburner” as 19,200lbf, while the whole defense community knows RD-93’s thrust is 18,300lbf and the only real thrust increase was achieved with its new re-designed Sea Wasp RD-33MK engines- which has been explicitly stated by Klimov. However, Klimov’s RD-33 series 3(or series 2?), whose avatar is RD-93 with re-positioned Gear boxes, has a provision for emergency thrust which Klimov says can produce 8700kgf(~19200lbf) in their officially released document. They further state that as “Take-off emergency mode”. So the mentioned thrust can only be used during take-off where the Air is denser, and also only during emergency situations since it would seriously lower the engine’s lifespan. This is a far cry from PAC's “Combat thrust” claim. Hence the true, lower than published, specifications of Chinese and Pakistani components are open to any one’s guesses. In any case, the close combat capabilities of JF-17 is below average or average at best.
The next Achilles heal is JF-17’s speed. For a good interception, speed is an important criteria. However JF-17’s max speed is Mach 1.6 which is claimed by PAC. This indicates that JF-17 is draggier. When compared, their F-7s(Reverse engineered Mig-21s) have higher speed of mach 2+ with a lower thrust engine. The IAF fighters which it is going to face, all have speeds greater than the Thunder.
