will the JF-17 Block 3 use the KLJ-7A Aesa radar or will feature an AESA from Italy, France?
It's quite simple, actually.KLJ-7A has been finalized for Block III.
Hu Mingchun, head of the Nanjing Research Institute of Electronics Technology in Jiangsu province, said the KLJ-7A active phased array radar will give the JF-17 many advantages in an aerial combat.
"Our product will tremendously extend the fighter jet's detection range, giving it a much longer sight that will help it detect the enemy's aircraft before they do, and this is very important because in real combat if you see first, you fire first," he said. "The radar is capable of tracking dozens of targets and engaging several of them simultaneously. It also has a good jamming-resistant capacity that keeps the plane away from enemy's electronic interference."
The KLJ-7A radar can be mounted on light-or medium-weight fighter jets. It is one of the best of its kind in the world in terms of technology and capability, Hu said.

The possibility of the Europeans refusing export clearances to countries like Myanmar seeking an AESA upgrade for their Block 2's in future (or buying new Block 3's) on grounds of human rights abuses/technology concerns may have impacted PAF's decision in this regard.
And then, there is Nigeria with its own record as well.
It's quite simple, actually.
The PAF has a stock of SD-10 and C-802s. Switching to a non-Chinese radar will mean the Block-III can't use those munitions. Even in the case where the PAF wants better BVRAAM and AShM, the next-gen Chinese stuff is likelier to come sooner than any other option. In fact, who else would you consult for a supersonic AShM but the Chinese?
AVIC told Alan Warnes that the SD-10 won't be integrated to a Leonardo radar, so the Vixen 1000E offer would have had to come with tangible AAM offers to be serious. I guess Turkish AAMs, but those are in development and waiting for them would mean delaying the Block-III's combat entry, needlessly. Besides, why not wait for the next-gen of Chinese AAMs if you need a better AAM?If compatibility were the only reason for selecting KLJ-7A, Leonardo wouldn't be offering the Vixen at the first place.
Some say, SD-10A was a 'stop gap' until a better BVR AAM was inducted.
Regarding supersonic anti-ship missiles, a JF-17 was seen flying with 2x CM-400AKG which PAF says is 'integrated but not inducted'. We have seen the JF-17B, its larger nose cone.. essentially what the Block III upgrade will include.
There will not be a major improvement in range, and existing Block 2's with IFR (and AEW&C support) will do the ASV job just fine.

The CM-400AKG is a mini ballistic missile/airborne rocket (no air-breathing engine, just solid rocket motor/s), not a supersonic cruising missile like the CM-302 or BrahMos. It's not the same capability. I'd argue that if a cost-effective supersonic cruising AShM were doable on the JF-17, it'd happen from China a lot sooner than anyone else, and again, a Chinese radar will be necessary.
It depends on how much the JF-17's centerline hardpoint can handle, but it'll mean negating the fuel tanks and having relatively short range. OTOH, China can look at reducing the CM-302's warhead and instead have the missile rely on its terminal velocity to do damage. The South Africans had a similar concept back in the 1990s (LRTM). Don't doubt the Chinese's willingness to innovate, they literally came up with a solution analogous to the Rolling Airframe Missile and could do it for a lighter supersonic AShM if the demand was there.A-Darter and the under-development Marlin was an option. Pointless discussion now with the KLJ-7A finalized.
CM-400AKG may not be sea-skimming but does the same job with a high altitude approach. How good are ship air defences in intercepting a high flying 'mini ballistic missile' at Mach 4 and diving at the target at Mach 5.5 in the terminal stage?
Brahmos and CM-302 are much larger (and heavier) missiles, even the Su-30MKI can carry only 1x Brahmos under the fuselage. Not happening with light fighters like JF-17.
