India's Prime Minister Manmohan Singh will visit Washington in July for talks with President George W. Bush on defense purchases and nuclear cooperation, a newspaper report said Sunday. The Bush administration has offered New Delhi an upgraded version of the F-16 fighter jets and to explore the setting up of nuclear power plants to meet India's burgeoning energy needs, The Indian Express reported. While Singh's government is amenable to the idea of improving India-US cooperation, the prime minister will have to work hard to convince his coalition partners belonging to different communist parties about closer defense and energy ties with Washington, the newspaper said.
