Is this happening now? or are you talking about a story of 15 years ago?If we are talking about rumors and their veracity, then I can share with you a story that PN is considering or in negotiations with the Chinese for 04 DDGs, of which one is presently going through the MLU program (052Bs), and the other is slated for MLU in the very near future (051Cs).
Would anyone believe it, and it comes from the same source who announced the induction of the 054A in the PN when the 054As had just begun?
The notion is that everything began as rumors before becoming reality, often without fully maturing.
I don't think Pakistan Navy would be interested in these two types now. They are both mainly equipped with Russian weapons and electronics before MLU and after MLU they are both almost larger displacement Type 054As. They cannot afford the long / middle range air defence and fleet battle command center requirement of PN.
I think if Pakistan were to introduce from or co-develop with China for a new type destroyer, it would be highly possible based on the Type 052D. The Type 052D is a perfect compromise between performance and price, so China built a lot for the PLAN. It's also an ideal warship for Pakistan to confront its enemy.
