The first JF-17s that flew in pakistani airspace on the occasion of 23rd march were built in China and brought in semi-knocked down state. They were re-assembled and painted in pakistan/china colors and flown on 23rd march, 2007.
Then in Jan 2008, Kamra started limited batch production. Here the planes were brought in a more knocked down parts and were assembled in Kamra. The flight testing facility was commissioned so the plane were assembled and flight testing was performed here. During that time till now, other facilities for manufacturing and avionics were being gradually set-up.
June 2009 saw the commencement of full serial production of the JF-17. Some parts are being imported from china and some will start local production. Gradually, this local production will increase to about 60% of airframe and 80% of avionics by 2010-11.
While individual parts are in the thousands, let me tell you what will be produced in pakistan. Both the wings, tail section and front fuselage. Real fuselage that will house the Russian engine and later (most probably) the chinese engine, will be made in China (atleast the parts with possible assembly at Kamra). This is for the 150 planes initial agreement with China. Pakistan will however have full ToT and, if at a later stage have the finances and decides to go for it, will be able to make 100% of the airframe. The engine, as we all know, will be foreign.
Hope that clears it up.
