The U.S. Secretary of State Hillary Clinton will focus her India visit early next month on the issue of non-proliferation, reported the Press Trust of India on Saturday.

"The Secretary will be in India, both in Delhi and in Calcutta. She'll have a chance in the context of our bilateral dialogue to talk about the full range of issues, including non-proliferation issues," the U.S. State Department spokesperson Victoria Nuland was quoted as saying in Washington.

The spokesman was responding to questions on the Agni V intercontinental missile test by India this month and a later medium-range missile test by Pakistan, according to the report.

The U.S. had then called for restraint of such tests.

Hillary Clinton is due to visit India on May 6 after visiting China and Bangladesh.
