State Department spokesman Sean McCormack said in a statement that India's National Security Advisor MK Narayanan, Department of Atomic Energy Chairman Anil Kakodkar, and Foreign Secretary Shivshankar Menon will be in Washington on July 16-19 for talks on the two countries' Nuclear Cooperation Initiative, which includes a pact for bilateral peaceful nuclear cooperation known as the 123 agreement.

They will meet Under Secretary of State for Political Affairs R. Nicholas Burns, National Security Advisor Stephen Hadley and other top US officials in hopes crafting a final agreement.

India and the United States have been discussing the fine print of the accord for two years after Washington agreed in principle to reverse three decades of US sanctions on nuclear trade with India.

"The United States stands ready to resolve the remaining outstanding issues on the 123 agreement," McCormack said.

"The United States understands the importance of the agreement to our relationship and the benefits it will bring to both nations. We are confident that with continued hard work, flexibility, and good spirit, we will reach a final agreement."
