Because it is their most advanced attack helicopter project right now...China has never exported to Pakistan it's top of the line stuff.I don't see that changing.
The WZ 10 may be sold to Pakistan but only years down the line.Not anytime soon.
Who said they have not sold us or given us their state of the art equipment ??
They offered us the J-10 way back in 2005-06 when they had not even officially declassified the plane, our president was given a tour of the manufacturing plant.
JF-17s have their best avionics suite, same radar tech which is in their J-10s, offered us their latest PGMs and other missiles.
Their AEW&C tech is their latest thing, which we will be getting by end of this year.
FC-20 would be the most advanced version of the J-10 series, and we would be among the first ones to operate it.
Similarly, for the next block of JF-17s, they have already started testing their most advanced avionics suite available.
PAF F-7PGs were more advanced compared to any series of J-7s, when PAF got them.
Tank technology is latest from them and we have improved many things and gave new features to them, SSMs tech is from them, their SLC-2 weapon locating radars are latest as per their tech & we have them, AR-1 300 barrel system for them are latest and we have them, F-22Ps have their advanced tech and we have them, they have offered us their Type-054As, which is also the latest among the lot, they have offered us their submarines, and knowing we operate one of the best available sub fleet, they will show us their latest tech also, recently the PA COAS chief was given a live firing demo of their latest UCAV & was offered for sale.
Many more examples of their latest tech having been given to Pakistan and currently on offer also.
Plus, they know very well that, if they don't provide, we can buy from somewhere else also, platforms which are much more high tech, durable and efficient and combat proven also, plus PA has already started to talk with the Turks regarding the T-129s and strong possibility that we will test them and even get them.
