Yup they did...
But why not the, from what I heard the JF-17 isn't that bad a plane. Its probably easier to maintain though possibly requiring more maintenence per flight hour than a western jet. Cheaper and until someone matches it up against an F-16 (aka the bellybutton seems everyones got one it used to be the Mig-21's byline) and I am sure thats going to happen soon with the Pakistani Air Force and the data is let out. Seems like a good deal also it does come without the western restrictions that are sometimes imposed.
Its like buying a VW or a Skoda why buy a VW for the price of a VW you can buy a new Skoda and you get all the toys with the Skoda... So the badge isn't too shiny (I am not being disrespectful there to anyone)...
