The G-20 leaders' statement did not detail how the nations would enforce those rules.

In a related measure, the leaders also agreed to set new executive compensation standards that would avoid risky-taking, like 'avoiding' multi-year guaranteed bonuses and requiring stronger disclosure for compensation policies.

The leaders asked firms to start putting into place such compensation suggestions, but didn't lay out a method for enforcing them. They also asked a G-20 advisory board to suggest more executive pay measures by next March.

Earlier, addressing the plenary session of the summit, Prime Minister Manmohan Singh said the time was not ripe yet to withdraw the stimulus packages, while raising India's concern over protectionism.

The current global financial crisis required tackling the problems at the root to restore normalcy in the global economy, he said.

'This requires a commitment that we will not undertake any premature withdrawal of stimulus. We must certainly plan for an orderly exit when the time is right. But that time is not now,' the prime minister said.
