You can clearly see at the moment in this year almost 4-5 countries are reportedly interested in buying the jf 17 thunder made by Pakistan with the help of China.
Couple of days back Pakistan started working on increasing the number of jf 17 thunder from current 70 to 250 which i think will be good for the Pakistan Air Force. At the moment there are a total of 4 Squadrons of jf 17 thunder named as 'Tail Choppers, Black Panthers, Black Spiders and Dashings'.
Black Panthers :
Black Spider : PAF JF-17 Thunder serial number 13-143 of No. 26 "Black Spiders" Squadron.
How many countries are interested, that is not a big deal. Actual problem is to get rid of aging F-7 & Mirages ASAP. Geo strategic issues are now Geo economic game. So A strong AF is need of hour.
