Russia is in a bad economic state and despite the risks involved in exporting equipment to China, it is doing so to support its economic status.
Russia would stop trade with China provided another customer is available for its equipment. India comes into picture here. Russia knows that selling to China is suicide for Russia's export business. China started with all the help from Russia. Now its already selling JF-17. Soon it will be J10, J11 and what not.
Russia would certainly look towards India from now on. India does not have the intention of copying and selling stuff and moreover, India Russia ties go far beyond a buyer seller relationship.
Seems like you love to kiss Russian ***!
China is already buying less of Russian gear unlike India!
