Security worries led the heads of the World Bank and International Monetary Fund to give final approval to scaling back their annual meeting in Washington DC.
The lending organisations' annual autumn meeting will be limited to the weekend of September 29th-30th, officials said in a statement. Originally, they had planned to meet a few days before that weekend until October 3rd.
A spokesman for Washington Mayor Anthony Williams praised the decision.
"It's going to help us eliminate inconveniences to residents and commuters," Mr Tony Bullock said. "It's going to reduce costs to taxpayers."
The IMF and World Bank said they "fully share the interest of the US authorities" in ensuring the least possible disruption to the nation's capital.
Protests directed at the organisations had been planned for September 28th through October 4th, and Washington police have been preparing a massive security operation. Police are expecting some 40,000 demonstrators.
District of Columbia officials have asked the US government to underwrite the extra costs of providing security. Executive assistant police chief Mr Terrance Gainer said the city would seek roughly $38 million to pay for policing the two-day event.
