"The long negotiations on the delivery of Su-35 to China are over, we have signed a contract," Chemezov said as quoted by the Russian Kommersant daily on Thursday.
The Su-35 fighter jet (NATO reporting name Flanker-E) is an upgraded version of the Su-27 multirole fighter. It was first introduced to a foreign audience at the 2013 Paris Air Show.
Indonesia, Brazil and the United Arab Emirates have also expressed interest in purchasing Su-35 jets, according to Rostec.
On Wednesday, Indonesian Ambassador to Russia Djauhari Oratmangun said that a Russian-Indonesian joint commission on military-technical cooperation will discuss the purchase of the Russian Sukhoi Su-35 fighters in late November in Jakarta.
