WASHINGTON: Indian Prime Minister Manmohan Singh said the world must press Pakistan to stop supporting terrorists who continue to target India.

Singh, speaking on the eve of an elaborate White House state visit, also urged Pakistan to bring to justice those who planned the Mumbai terror attacks, which left 166 people dead a year ago.

Singh said it was the right decision to resist the ‘inordinate pressure’ he faced to respond to the attack that shocked and angered India.

But Pakistan ‘should be pressurised by the world community to do much more to bring to book all those people who are responsible for this horrible crime,’ Singh said at the Council on Foreign Relations. ‘The trauma of the attack continues to haunt us.’

He urged his neighbor to control the terror groups that he said have moved from the border region with Afghanistan into Pakistan’s heartland.

Failure to do so, Singh said, will result in serious consequences for the stability of both Pakistan and India.

The White House state visit Tuesday for Singh, the first in President Barack Obama’s White House, is meant to show the US administration’s eagerness to win Indian cooperation on counterterror, trade and climate change initiatives.

India, however, has watched with wariness as Obama has lavished attention on rivals Pakistan and China.

In an attempt to ease another source of US-Indian tension, Singh said that Indian and US officials will sign a memorandum Tuesday intended to improve cooperation on energy security, clean energy and climate change. He did not provide details.

Developing and industrialised countries have bickered as they prepare to negotiate a new global climate change treaty, at a December summit in Copenhagen, Denmark, meant to replace the 1997 Kyoto Protocol on carbon dioxide emissions.

Singh said all countries must make an effort to make Copenhagen a success, despite difficult negotiations.

‘We are determined to be part of the solution to the problem,’ he said.

India is willing to work on any solution that does not hurt developing countries’ efforts to lift their populations out of poverty, Singh said
