European leaders and finance ministers meet in Berlin Sunday to draw up an action plan to combat the world economic crisis and beef up market regulation amid the threat of a financial meltdown in Central and Eastern Europe, according to dpa. Hosted by German Chancellor Angela Merkel, Sunday's meeting has been called to set out Europe's position on plotting financial market reform, and measures to tackle the recession ahead of the April summit in London of the Group of 20 (G20) major economic powers. But this week's dramatic sell-off in markets across CEE states and warnings about the fragile state of the region's banking sector has meant Sunday's meeting of the seven key European Union (EU) nations will have to consider the more immediate problem of helping to shore up the CEE financial system.
