Very rarely, By the time its told to the public its usually something they have already talked it over, its especially true if they(forces) reallly want it.Question for more knowing folks about this possible deal for J-35, KJ-500, HQ-19, has there ever been the case in the past where the pakistani government (strictly the government, discounting any rumours/unofficial sources) made public offers on various chinese weapons systems that did not materialized in firm contracts/ deliveries? I see some argue that since at present it's only an offer it doesn't necessarily means it's a done deal, so trying to find out about such instances in the past.
But apparently Pakistan PM/FM is apparently going to visit China in june/july so maybe we will find out some more details by then?
