Russian initially blocked its sale of Kilmov RD-93 engine for JF 17 thunder saying the following as quoted by Colonel-General Anatoly Mazurkevich: "We've denied China the right to supply its JF-17 fighter aircraft powered by Russian RD-93 engines to third countries, asking it to sign an end-user certificate for the engines," Speaking to Indian and Russian journalists ahead of a visit to India by Russia's Deputy Prime Minister and Defence Minister Sergei Ivanov on January 22,2007 Col.-Gen. Mazurkevich confirmed that India and Russia are shortly to sign accords to jointly develop and produce a 5th generation fighter plane and a multi-role transport aircraft. Later on President Vladimir Putin personally supervised the deal and inked sanctioning documents, representatives of president’s administration specified. The deal was backed up by all parties concerned – Defense Ministry, Federal Industry Agency and Rosoboron export, which is the state exporter of weapons. Now, I can understand that the deal was pure business on Russia's part, but why did'nt they care about the Indian Lobby's protest? Why irk India, when it is one of the principal buyers of Russian defence equipments at the expense of potential sale of 1000 RD-93 engines for Chinese export? Its simply not good business when they are many countries vying to get a piece of Indian defence contracts!! P.S: I am not sure if this topic has been discussed earlier, so tried using forums search engine and nothing showed up.
