London, Mar.27 British Foreign Office Minister Lord Malloch-Brown has warned leaders of the world's biggest economies yesterday to produce more than empty rhetoric at the crucial G20 summit in London next week.

Plain speaking Brown is playing a key role in the negotiations ahead of the meeting, and said: "We can't again engage in meaningless, empty commitments which don't survive the flight home."

According to The Independent, he said these leaders risked fuelling public dissent if they did not agree on action to tackle the recession.

He said Thursday's summit might not have an immediate impact.

"The global economy is going to go on descending on 3 April, the massive destruction of wealth that is going on is not going to be stopped by any leaders' communiqui. Stock markets may be arrested and turned around but we are in for a very tough 2009 under any circumstances - including a successful G20 summit." (ANI)
