A ban on trading nuclear technology and materials with India is expected to be lifted after a controversial agreement in Vienna. It came after 45 nations of the Nuclear Suppliers Group were won over by the US, which is seeking to complete an atomic energy deal with India.
It has raised concerns among the international communtiy as India has never signed up to the almost universal Non-Proliferation Treaty, which is meant to stop the spread and production of nuclear weapons.
Washington says the fuel and technology deal would forge a strategic partnership with India that would help it meet its soaring energy demands.
The final hurdle to be overcome is ratification by the US Congress. That has to happen before late September when Congress adjourns for elections. If it does not go through the deal could face an uncertain fate under a new administration.
