Mrs Clinton is keen to sign lucrative trade deals with India

Indian relations with Pakistan are thought to be high on the agenda, along with education and technology.

The countries are also expected to sign deals on arms sales and the building of US-funded nuclear plants.

Correspondents say the visit aims to show the US is committed to Delhi, and to broaden ties between the countries.

As well as Mr Singh, Mrs Clinton will hold talks with her Indian counterpart, SM Krishna, the head of the ruling Congress Party, Sonia Gandhi, and the leader of the opposition², Lal Krishna Advani.

The BBC's Kim Ghattas, who is travelling with Mrs Clinton, says the secretary of state hopes to come away with tangible³（实体的，明白的） agreements on trade between the US and India.

She is particularly keen to open doors to lucrative（获利的，合算的） US deals in arms and civilian⁴ nuclear energy, says our correspondent.

India's relations with neighbouring Pakistan are expected to feature prominently in discussions.

The BBC's Sanjoy Majumder in Delhi says that publicly Mrs Clinton has insisted that what Pakistan and India do is completely up to them.

However, he says that everyone in Delhi is clear that it was pressure from Washington that pushed the countries to hold talks in Sharm el-Sheikh in Egypt last week.

Pakistan-India relations dominated Mrs Clinton's visit to Mumbai, in the wake of attacks on the city last November that left more than 170 people dead.

India blamed Pakistan-based militants⁵ for the attack.

Much of the US focus in the region has been on countering militancy⁶ in Pakistan and Afghanistan.

Climate disagreements

Mrs Clinton spent the first two days of her five-day visit in Mumbai.

Then in Delhi on Sunday, talks focused on climate change, which remains⁷ a sensitive subject for developing countries such as India and China, who have so far refused to commit to carbon emissions⁸ cuts in a new treaty.

Mrs Clinton also sought to assure India the US would not try to impose conditions that might affect India's economic growth.

But Indian Environment Minister Jairam Ramesh said his government could not accept targets that would limit economic growth.

India argues the US must do more as it has been historically to blame for the emissions.

Mrs Clinton later told reporters she was optimistic a deal on climate change could be reached.

"It's part of a give-and-take and it's multilateral（多边的，多国参加的）, which makes it even more complex," she said, during a tour of an agricultural research facility.

"Until proven otherwise, I'm going to continue to speak out in favour of every country doing its part to deal with the challenge of global climate change."

The key date for climate change is December - when a summit in Copenhagen, Denmark will look to forge（打制，伪造） a new international treaty that will replace the Kyoto Protocol⁹, which expires（期满，世界） in 2012.
