Mr. Sancho sir,
The Russians have been giving/selling some tech to us which are not generally avalable, how do you think the Russians are going to react when it comes to those requirements?
They did and continue to do so, because we will remain their biggst partner in terms of defence, all that changes is, the way we deal with each other in these procurements and developments!
India is not only a simple buyer anymore for them and we have plenty of alternative options. That means they either have to offer us more quality weapons, which can compete with western counterparts (which wasn't the case for Mig 35 or Mi28 for example), or jointly develop them with us (Brahmos, FGFA, MTA, offers for join tank and helicopter development are on as well). By offering us co-development we get more access to techs, spares and indigenous production, but also more say on design and customisations for Indian specific requirements. At the same time, they will get a reliable and financially strong partner and don't have to fear western competition anymore, because no western country freely offers us such high techs as Russia does. That's why we constantly rejects F35, because we benefit way more from FGFA, while Russia still will get it's 200 - 300 exported fighters, like they did with MKI.
People also don't see that Russia itself is changing it's defence industry and their policies in these fields in a big way! In Soviet times they developed and produced everything on their own, just like China does. But times are changing and Russia today has access to western arms, as well to western industries as well. They don't want to remain with low quality arms, nor with low quality civil techs as well, that's why they now join with Europeans and even US companies to procure techs (engines avionics...), to procure arms (LHDs, helicopters, armoured vehicles), or even to jointly develop them, just like we do as well. In the long term this will improve Russian forces, but also Russian industry, because they get increased quality and more exports as well.
So Russia today and India are doing the same in terms of diversifying arms, techs and industrial options, while both still remain comitted to eachother, because they need our big market and we need their technological knowledge.
