Mumbai: Policymakers at the Europen Central Bank has asked Washington to do more to halt the dollar's decline after the dollar hit a record low against Europe's single currency euro.

The US currency fell below $1.50 a euro last week. The euro, which traded for just over 80 US cents at its lowest in 2000, hit a record $1.5275 last week, making life harder for euro zone exporters in world markets.

"Things are becoming exaggerated," Guy Quaden, Belgium's representative at the European Central Bank, said in an interview on Belgian radio.

"It's up to the relevant authorities to assume their responsibilities and particularly for US authorities, who repeat that they are in favor of a strong dollar but who should reaffirm their words," he told a meeting of European policymakers in Brussels.

"We are also happy to see the reaction in the US. They are also concerned about that. So it may be a first step to a good collaboration between Europe and the US in this field," added Belgian finance minister Didier Reynders.

French prime minister Francois Fillon echoed similar declarations overnight at a Brussels meeting of the euro zone's finance ministers and ECB president Jean-Claude Trichet.

The ECB had intervened in currency markets in 2000 to stem the euro's slide, but it is unlikely to do so now to reverse the slide in exchange rate.
