Is there even a need? All China needs to do is provide Pakistan the approximate location of the Indian strike groups. Pakistan has anti carrier missiles that can reach out to 300 km, and it’s available for both JF-17 and J-10. A PAF contingent of a dozen aircraft, with a tanker and AWAC, along with a few PN ships, will be more than enough to take care of both carrier strike groups with ease. This isn’t a USN carrier group, it’s Indian one. They have much less situational awareness and their MiG-29s are terribly outclassed by both J-10 and JF-17I disagree, because china can also take out India in a nuclear exchange. India leadership isn't interested in mutual assured destruction. Neither is USA interested in a hyperinflation for the next 10 years.
Selling hypersonic missile to pakistan will piss off indians for sure, but it would be against the missile export restriction. I believe its limited to less than 300km, and that is pretty much useless, because indian carrier would be parked outside the 300km.
not to mention, china probably don't want the technology leak, because hypersonice anti carrier missile is china's ace card against american carrier. uncle sam will be more than happy to give a few trillion loan to get some samples.
If Pakistan is to make a significant land move into Kashmir, it’s only logical to strike hard at the IN simultaneously. Maybe this is what is in the works..
