Ministers and central bank governors from the 17 countries using the euro and the broader 27-nation European Union met on Friday and Saturday in the Polish city of Wroclaw to discuss Europe's slowing economic growth and progress in beefing up euro zone defenses against the sovereign debt crisis.

In an unprecedented visit to the informal talks of top EU financial officials, US Treasury Secretary Timothy Geithner made an appearance in Wroclaw on Friday to urge Germany to provide more fiscal stimulus to the slackening euro zone.

But Geithner's call for action by those who can afford it was rejected because the euro zone believes that market trust in the sustainability of its public finances, and therefore consolidation, is more important than spending on growth.

Greece's finance minister on Saturday dismissed talk that the debt-strapped country was headed for default, while saying Prime Minister George Papandreou canceled a trip to the United States because tough decisions had to be made imminently.
