Egypt became one of the first export customers when in 1974 bought eight MiG-23MS interceptors, eight MiG-23BN strikers and four MIG-23U trainers, concentrating them into a single regiment based at Mersa Matruh. By 1975 all Egyptian MiG-23s had been withdrawn from active duty and placed in storage due to the Egyptian foreign policy shifting towards the West and thus losing USSR support.
In 1978 China purchased two MiG-23MS interceptors, two MiG-23BNs, two MiG-23Us, ten MiG-21MFs, and ten
KSR-2 (AS-5 Kelt) air-to-surface missiles in exchange for spare parts and technical support for the Egyptian fleet of Soviet-supplied MiG-17 Frescos and MiG-21s. The Chinese used the aircraft as the basis for their
J-9 project, which never ventured beyond the research phase.
Some time later the remaining six MiG-23MS examples and six MiG-23BNs, as well as 16 MiG-21MFs, two Sukhoi Su-20 Fitters, two MiG-21Us, two Mil Mi-8 Hips and ten KSR-2 were purchased for the Foreign Technology Division, a special department of the USAF, responsible for evaluating adversary technologies. These were exchanged for weapons and spares support, including AIM-9J/P Sidewinder missiles, which were installed on remaining Egyptian MiG-21s.
