National Security Adviser Shivshankar Menon said, India and the US will open a long-term framework of strategic cooperation during President Barack Obama visit to New Delhi. He also underlined that the two sides must be sensitive to each other's national interests. Mr Menon was speaking at the Carnegie Endowment for International Peace – a Washington-based think-tank yesterday. He said, the visit offers an opportunity to put into place a longer term framework for India-US strategic partnership, and to add content to that partnership in several areas that are now ripe. Giving the first official indication of the things to be expected during the Obama visit to India in November, Mr. Menon said, the goal must be to gear the bilateral cooperation towards making the two countries stronger, safer and more prosperous. He said, both the sides must strengthen the habit of working together, besides intensifying strategic consultations.Mr. Menon also asserted that there is no surmountable problem in the Nuclear Liability Bill, saying New Delhi hopes to finish the work on implementation of civilian nuclear bill before the visit of Obama and then start commercial negotiations. Mr. Menon left Washington yesterday after holding intense consultations with top US officials on issues related to the visit of President Obama to India in November. Among others, he met Secretary of State Hillary Clinton and his American counterpart General retired James Jones. A major area for initiatives is the economy and trade, Mr. Menon noted, saying India today offers a growing market and a partner in improving the international competitiveness of US companies, creating jobs in both countries.
