The production line being kept open is in India where those particular SU-30s are made.

It is understandable that the MiG-29s remaining in the Indian inventory will be upgraded by the original manufacturer. But it should be noted that India just awarded a very large order to the French for Rafales. And they also ordered P-8s from us and I believe some C-130Js. Then they just accepted or are about to accept the Akula class boat they are leasing from the Russians.

So it is a bit of a mixed bag. They seem to be trending away from Russian equipment. One reason is the Russkis are hard to deal with. Amongst other things a deal may not really be a deal with those guys. They have a rep of coming back midway through an arrangement and asking for more money.
