It is a "much scaled down request. In view of the constraints that we have on resources, we have now a far less ambitious package which is a mix of some old, used aircraft and some new," visiting Pakistan Foreign Secretary Riaz Khan told a joint news conference with US undersecretary of state Nicholas Burns.

He said he did not have all the details of the package.

"As regards the specific details of this package, I'll give you the basic fact, which is that it is a scaled down request. But exactly what are the numbers involved -- what were before because these things keeping on getting revised. So what numbers we may have started with, I even don't know that and I have rough idea as to what we have requested now.

" Khan said he was not really in a position to make a comparison as to what was in "our minds before and what it is that we have asked now, but it is a scaled-down, much scaled-down request and it is a mix, as I said, that this is no longer all new aircraft." burns said the us had received the request for the sale of F-16 aircraft from Pakistan to move forward and that Washington intends to begin its consultations on the issue with Congress shortly.

"We notified Congress several weeks ago. We've been talking to members and their staffs, but we'll present our views formally and in detail to Congress very shortly," Burns said at the end of the two-day bilateral strategic dialogue with Khan.
