Europe cannot be looked at as a homogeneous group. Frankly speaking, Italy was offering Grifo radars to Pakistan at the height of the 90's arms embargoes. Pakistan has a long standing working relationship with Selex (formerly FIAR and a subsidiary of Finmeccanica) and had, in the 90s, acquired Grifo 7 radar for the F-7P which was replaced by the Grifo Mk-II (under licensed production) and the F-7PG was fitted with the Grifo MG (also under lisenced assembly). Subsequently for Project ROSE, Mirage III was fitted with the Grifo M3 radar. Following this the Grifo S (or S7) was designed specifically to compete for the then Super 7 (now JF-17) project and was offered when other countries were not ready to offer anything. Even when France pulled the RC-400 under Indian pressure the Grifo S was on offer. No the KLJ-7 performed admirably so it was ultimately selected (also probably was cheaper), but all of this occurred at the height of the Nuclear embargoes so I see little risk in pursuing the Italian radar and electronics package. Additionally, though we may be wary of the UK, it has only ever blocked Nuclear/dual use tech and I doubt would have the need to block (if they have a veto) a Selex electronics sale to Pakistan. Additionally the J-10B/C are already using advanced AESA radars and IRST, so I dont know what benefit they would see from blocking this to Pakistan as it relates to China. Europe is not the US which is actively using F-16s as are many of its anti-Chinese allies in Asia (Taiwan, Singapore, Phillipines, Japan(in the form of F-2)) and so doesnt want the Chinese to know anything about the F-16s capabilities and sensors. Europe has no such issue other than IP which as I said is kinda a moot point with similar sensors and electronics manufactured in China. The 2 things mentioned that really intrigue me are the miysis and brightcloud systems which would be great for PAF JF-17s and a good option to offer for potential sale.
I agree with
@MastanKhan that south african weapons should be actively sought, especially a-darter and Marlin. The A-darter will be especially useful for the HOBS which can be married to a SA HMD. This could be then translated to even the F-7PGs which are planned to serve into the 2020's (id imagine at least another 10 years) and the ROSE III Mirages. This would give a degree of BVR capabilities (as the Missile has a 25km range) and the jets can be vectored in by AWACs against intruding airforces and fire off missiles in a shoot and scoot type action. With the A-darter's high degree of manouverability and lock-after-launch capabilities, it would make for a very effective weapon for these aircraft which have some BVR range capability (albeit minimum). They dont need to be close enough to achieve missile lock given the lock after launch but can fire from stand off range and get out. Given the PG's point defense nature it would be an optimal weapon for it to remain relevant against the IAF.
For export, it will make the JF-17 that much more attractive to have options, especially when most of those would be free of strings. Of note, with Rafale being a low-rcs aircraft and the potential of PAK-FA, the inclusion of an IRST like Selex's Skyward-G will keep the JF-17 relevant for a long time to come. Any addition of A-darter will be able to be fully utilized with IRST. Given the size similarity of Gripen and JF-17, I have no doubt that Selex can find a solution for a permanent IRST in the nose just forward the cockpit of the JF-17.
