where is the chinese engine?
Officials at the Farnborough International Airshow in August 2010 stated that a JF-17 development aircraft is flying with a Chinese engine, which is most likely to be the WS-13.
Guizhou WS-13 - Wikipedia, the free encyclopedia

Arsalan you are forgetting RD-93 issues with such load configuration.
This also support what most of us know so RD93 wont be a problem carrying this load that will be around 3200Kg!all the load/ stress testing (200% with wing bend and twist verification) has been done with RD-93 onboard, the aircraft is now qualified to carry additional payloads.
Currently not mature enough to be termed as better than the RD-93 in all aspects including reliability.
And the PAF already has its inventory of RD-93s ordered for its current 150 aircraft
rd-93 is a good engine compared to f7 and mirage engines (aircraft its replacing), the problem lies with thrust and ab thrust which is GReater then 2 lb for each lb of thrust generated, compared to western engines like ge or even al-31 (1.7 or 1.8 lb/lb in ab wand .67lb /lb in dry thrust)which is less then 2 lb per lb of thrust. Tbo has been improved but not near western engines, but its 1/2 the prices of any western engine too. So cannot have it both ways. I think best way is to improve internal fuel capacity of if-17 from current 2330 kg to say 2700-2800 kg like mirage 5 or other fighters in the class if it is some how possible, ie better fuel fraction, with external tanks it fuel load is good.

what about improving dry thrust and decreasing the weight of the fighter
