European Union finance ministers, meeting in Brussels, backed a German call for tougher sanctions in future against states that flout the bloc's budget rules, to prevent any repeat of Greece's debt crisis, which required a euro zone/IMF bailout.

Worries persisted that Greece's debt troubles would spread to other indebted nations, dragging down Europe's economy and curtailing trade to the United States and Asia.

European officials were eager to show they were committed to bringing down deficits without smothering a still-fragile recovery. European Central Bank President Jean-Claude Trichet sought to calm nervous markets by declaring the euro was not in danger.

Both chambers of parliament approved Berlin's contribution of up to EUR148 billion (US$183.8 billion) in loan guarantees, deeply unpopular with voters, on top of an equally divisive EUR22.4 billion in bilateral loans for debt-ridden Greece.

The bill passed the lower house by 319 votes to 73 with 195 abstentions after the opposition Social Democrats and Greens abstained and 10 members of Chancellor Angela Merkel's center-right coalition rebelled, highlighting the domestic pressure she faces.

The vote was not enough to stop the fall in European shares, which lost a further 0.5 percent on the day after Asian stock markets slid again. Japan's Nikkei average closed 2.5 percent down for a loss of 6.5 percent on the week, mostly due to worries about the euro zone.

Merkel said the parliamentary vote was a clear German message of support for Europe.
