Qamar spoke to Aviation Week in Melbourne where he was attending an air chiefs' conference.
The US Congress in 2006 had agreed to give Pakistan 28 F-16C/Ds under an excess defence articles initiative.
The first 14 aircraft were recently delivered.
"Qamar says negotiations are ongoing for the remaining 14," the Aviation Week said.
Pakistan has a total of 63 F-16s—45 A/Bs and 18 C/Ds.
"Qamar says all the A/Bs are to undergo a mid-life upgrade and become C/D aircraft 'close to Block 50' standard by 2013-14. The first three A/ Bs are being upgraded at Turkish Aerospace Industries," the report said.
According to Aviation Week, Pakistan is also jointly developing the JF-17 fighter, which is being produced at the Pakistan Aeronautical Complex in Kamra.
Qamar said the second squadron of JF-17s will go into operation in late March, and at that time the Chinese Nanchang A-5, a ground attack aircraft, will begin to be phased out, the report said.
