While this is an old article, I find it most interesting. Here, Vietnam used a Belarus Design house to design their "own" MALE UAV. This is an interesting model, since such a UAV or UCAV is not permitted for export due to MTCR. Pakistan could also work on this model, instead of buying or copying the CH family (CH-3 Burraq), and CH4 and CH5 being evaluated for UCAV, it is a difficult time internationally for the country to be toying with a potential MTCR violation. Many western governments would be waiting to victimize the country further.
Working on the Vietnamese model, a Belarus development partner could co-design the UAV/UCAV in Pakistan, and setup the design house and production line. This shall enable Pakistan to receive an indigenous capability, not violate any crucial laws, and continue the development towards a more robust MALE and UAV capability.
