It's worth noting that if Pakistan was genuinely interested, it'd take a few years to just draft the accord/agreement. MMU is serious. It'd take a lot of negotiation, audits, and investigation to figure out offsets, co-production, IP sharing, etc. The amount of money involved would be as much as CPEC.
You gotta be kidding me. Designing, testing, and manufactering a 5th generation fighter is no easy task and something which cant be done by 90% of nations in the world but to put it at CPEC level of technical expertise or funding would be a joke/mistatement. CPEC covers a wide range of different projects estimated at 60bn today more than likely reaching 100bn over the next decade.
In our part of the cost of manufactering/labor/matierials are super cheap compared to developed countries.Give me 5bn USD and ill give you a 5th generation manufactering plant at KAMRA, a few initial prototypes as well as the first squadron of the jets within 5 years
If you broke the 5bn up I believe the PAF has already spent atleast 500million USD now on the AZM program overall. No clear figures just an estimate. Now going forward work will be split with the Turks. Both sides will start off with the existing infrastructure that has already been developed and go from there.
