"India is fully committed to safeguard its security as a nuclear weapons state and to deepen its autonomous, scientific and technical capability for meeting its security imperatives as well as its developmental goals," External Affairs Minister Natwar Singh told the Rajya Sabha, India's upper house of Parliament.
The Lok Sabha, or the lower house, passed the bill Tuesday.
The Weapons of Mass Destruction and their Delivery Systems (Prohibition of Unlawful Activities) Bill seeks to prevent the leakage of missile technology to terrorist groups or states that are seeking to build nuclear weapons.
"India is and will remain a responsible nuclear power," Singh said. "Our policy is not to encourage other nations to develop nuclear weapons."
Nuclear proliferation has become a global concern after it emerged that A.Q. Khan, the father of the Pakistani nuclear program, had run an international proliferation network selling technology to countries such as Iran and Libya.
