Tokyo stocks tumbled Monday with the benchmark Nikkei stock index falling 2.17 percent to its lowest closing level in 30 months over fears the eurozone debt crisis cannot be contained and concerns there is a global economic slowdown.

Market players here pointed to an emergency statement made by financial chiefs from the Group of 20 advanced and emerging economies made last Thursday, with the purpose of settling concerns about sovereign debt in the eurozone and the outlook for the global economy, as failing to achieve its objective.

"We are committed to supporting growth, implementing credible fiscal consolidation plans, and ensuring strong sustainable growth, " the emergency communique said. "This will require a collective and bold action plan with everyone doing their part."

But analysts here said the statement did little to inspire confidence in European and global markets as there was no mention of any concrete action plans to boost support for Europe and was largely dismissed as more rhetoric.

Contributing to a sour market mood on Monday, the financial chiefs failed to mention a collective vision or stance on how Greece's likely debt default will be dealt with, exacerbating global concern.

In response, U.S. Treasury Secretary Timothy F. Geithner called European policy makers to arms at the end of last week and demanded that they redouble their efforts to combat the single currency region's debt crisis, or risk the "threat of cascading default, bank runs and catastrophic risk."
