Lol China made JF-17 operational in 4 years, it first flew in 2003 and was inducted by PAF in 2007, similarly J-20 first flew in 2011 and became operational in 2017 just 6 years, these chinks think that the world is a fool taking decades.
Biggest advantage of them being in NATO and also with Russia, we should grow closer to both as we did a good think by buying S400 now America can’t sell its aircrafts citing S400 purchase but then they’ll lose some serious market as well so they’ll now offer products at a much better value.
They usually license produce things and label them as indigenous so maybe a RollsRoyce engine local production, why are they going for 120KN engines? Maybe they are making a heavy Category aircraft.
