Washington, July 16 - Acknowledging India's emergence as a global player, US Secretary of State Hillary Clinton says how New Delhi can 'play not just a regional role but a global one as well' would top her agenda on her India trip.

'We believe India has a tremendous opportunity and a growing responsibility, which they acknowledge, to play not just a regional role but a global one as well,' she said Wednesday in a speech to the Council on Foreign Relations.

'How they choose to define, that we will explore in-depth during the course of our discussion,' Clinton said ahead of what she described as a 'very broad, comprehensive dialogue' with India during her five-day visit starting Friday.

'It's the most wide-ranging that I think has ever been put on the table between India and the United States,' Clinton said.

'It has six pillars to it, one of which, of course, is foreign policy, strategic challenges, along with, you know, other matters like health, and education, and agriculture and the economy.'

US would welcome Indian leadership and involvement in a number of difficult areas including non-proliferation, she said.

'Anybody who ever read Strobe Talbott's book, 'Engaging India,' knows that it's a very difficult issue. But, we want to look at new ways for global and regional regimes on weapons of mass destruction, particularly nuclear.
