Russian media reported that after Rosoboron export, Russian’s state defense product export company, signed a 43 RD-93 aircraft engine contract with China in December 2009, Russia is likely to sign another contract with China to sell 100 more RD-93s. This engine is to be installed on FC-1 fighter. Currently, China signed another contract to sell 150 FC-1 to Pakistan (Pakistan will assemble the plane using the components provided by China).
Russian military experts believe that although China frequently claims it has made great progress in the R&D of the engines, the fact that it continues buying Russian engines indicates that China still lags behind. Exporting engines to China will allow Russia to control the capability of fighter planes that China exports.
