WASHINGTON - The world's top finance officials wrapped up three days of talks in Washington on Sunday after failing to reach a consensus on measures to head off what some see as a looming currency war.

The International Monetary Fund steering committee, which has been struggling to address friction among key economies, including China and the United States, said on Saturday the organization should continue its efforts to manage capital flows.

"While the international monetary system has proved resilient, tensions and vulnerabilities remain as a result of widening global imbalances, continued volatile capital flows, exchange rate movements and issues related to the supply and accumulation of official reserves," the IMF panel said in a statement after its meeting on Saturday.
