Turkey exports ACV-300 vehicles to Middile-east and Malaysia as well and Turkish army is also operating more than 1000 ACV-300 vehicles in different categories but I think ACV design with its obsolete armour doesn't meet the current requirements of modern armies so Otokar designed a new IFV which is able to respond modern threats in battlefied. FNSS (producer of ACV series) are also designing a new IFV to replace ACV-300 series.
A likely cooperation between Pakistan/Turkey on TulPar IFV would be a paradise like day for both nation because Tulpar is really strong and tank like vehicle which can be used on many different roles.
