"Out of the 14 technology groups in defence, India is barred from 10 of them in terms of tech-transfer. Out of the remaining four, technology transfer from two of them will not come for various reasons", Mitra, also the state finance and industry minister, said at a CII seminar on defence here.
He said that the remaining two groups would not bring the latest technologies to India and neither transfer them.
In August, the Narendra Modi-led BJP government approved hike in FDI in defence from 26 per cent to 49 per cent through the approval route in a Cabinet decision, which Trinamool Congress termed as a "backdoor entry".
Stating that Indian OEMs in the defence sector should be given a level playing field vis-a-vis the foreign counterparts, Mitra said that the taxation imbalance should be corrected.
Indian companies were subject to various taxes whereas foreign manufacturers were exempted from such levies.
