There was no problem getting licenses for local production of 6TD series, Ukraine is still offering that, it does not make economic sense for Pakistan to spend all the money required on R&D, supply chain, metallurgy, machinery etc that would enable it to produce engines locally because the volume of production is so small. That’s why PA didn’t get TOT for VT4 powertrain either despite Chinas insistence, it would raise per-tank cost by 30-35% as opposed to importing the engines directly from China. I’ve butted heads with HIT enough times over this already and that’s their answer, which in a sense is valid too, as much as I’d like them to bite the bullet and set up local engineer production capabilities, they have a valid point when they say that such capabilities must start from commercial automakers where production volume is higher and trickle down to HIT instead of the other way around
