Washington, July 22 - Secretary of State Hillary Clinton's visit to India has given a new momentum to India-US relationship, but differences over climate change and trade talks may cloud their 'strategic partnership', mainline US media suggests.

'The message Clinton sought to deliver was clear: the Obama administration wants to carry forward the momentum in bilateral relations gathered during the George W. Bush years,' Time magazine said.

'But as a near war of words over climate change showed, there is much ground to cover between rhetoric and reality, and the fledgling 'strategic partnership' is not likely to be an easy one,' it said

'The irony of the Indo-US strategic partnership remains that while the US may urge India to become a global power, neither country is ready for that to happen,' Time said pointing to differences over negotiations over the non-proliferation treaty, climate change and manufactured-goods tariffs at the WTO.

The Wall Street Journal hoped 'the Administration was paying attention to India's environment minister (Jairam Ramesh) when he told Clinton a thing or two about climate policy.'

'There is still serious scientific debate about the causes, effects and possible solutions for climate change,' it said. 'But if President Obama is determined to tackle the issue anyway, he could do worse than listen to what Ramesh said.
