"The interest was voiced at the highest level. It is known that the budget for the purchase of aircraft has already been formed for 2015-2016," Djauhari Oratmangun told RIA Novosti.
According to the diplomat, a decision concerning the purchase will be made by the end of 2016. The quantity of jets will depend on the tender results, he added.
The Su-35 jets are modern and well-equipped aircraft, Oratmangun said, stressing that these characteristics are important to Indonesia.
In June, Russia’s state-run arms exporter Rosoboronexport announced plans to participate in the Indonesian Air Force's bidding for multifunctional fighter jets, offering the Su-35.
