US Secretary of State Hillary Clinton is seeking greater security and nuclear ties on a visit to India.
Mrs Clinton said last week’s bombings in Mumbai (Bombay) had “driven home how important it is that we get results”.
She also called for deeper trade ties and heard Indian worries over US pullout plans from Afghanistan.
Following the talks with Indian Foreign Minister SM Krishna in Delhi, Mrs Clinton said she was “encouraged” peace moves with Pakistan had restarted.
Mrs Clinton said that counter-terrorism was an issue on everybody’s minds following last week’s bombings in Mumbai, which killed 20 people.
“We are deepening and expanding our efforts and making great strides together on behalf of counter-terrorism, but also in respect of maritime security,” she told a news conference.
She said she was “encouraged” by renewed dialogue between India and Pakistan, which was “so necessary for us to deal with the underlying problem of terrorism”.
India has not blamed Pakistan for last week’s attack, but the much deadlier 2008 assault derailed peace efforts between the regional rivals. Formal talks restarted only this year.
