NEW YORK, March 15 (Reuters) - World equities eased on Monday as investors awaited decisions from U.S. and Japanese central bank policy meetings this week, while oil and other commodities fell as the U.S. dollar strengthened.
Assets perceived as risky retreated amid numerous questions about monetary policy, the resolution of Greece's debt woes and worries that China may further tighten its monetary policy, which could throw a wrench in the recovery of the global economy. Almost all assets classes were swept by worries.
The euro slid on a lack of progress on a financial aid package for debt-strapped Greece, while gold rose as investors sought a haven from risk due to concerns over sovereign debt. For details see: [

The fears of further credit tightening by monetary authorities in China drove down stocks around the world.
In the United States, plans by U.S. Senate Banking Committee Chairman Christopher Dodd to unveil revised financial reform legislation also weighed on equities.
European stock markets closed down, with European banks also hit by worries over U.S. regulatory reform. The pan-European FTSEurofirst 300 <

"That China is making these moves is a sign that the economy could be stronger, but in the short-term there are concerns that we're not yet on a firm enough footing to stand this," said John Massey, portfolio manager at SunAmerica Asset Management in Jersey City, New Jersey.
