India's PM in Russia on a shopping mission

Russia may become the second important nuclear material supplier for India, following the US, which may bring further disorder on world mechanisms for nuclear nonproliferation as India is still a non-signer of the Nuclear Non-Proliferation Treaty (NPT), Chinese experts said.

Indian Prime Minister Manmohan Singh arrived in Moscow on Sunday for talks on a landmark deal that could significantly widen nuclear fuel imports from Russia.

The talks on a civilian nuclear deal to widen uranium fuel deliveries - and signing deals for aircraft and other military hardware - will be center stage during the three-day visit which ends today, Indian officials said.
