China said it was ready to pump more money into its economy as G20 finance ministers met to thrash out ways to fix the global economy and World Bank head Robert Zoellick warned against "doing too little, too late". "2009 is shaping up to be a very dangerous year," he told reporters at a news conference in London. The prospect of extra stimulus spending in China, which also saw a pick-up in trade, offered a glimmer of hope for investors and policymakers, while signs that big U.S. banks may be turning around helped lift global stocks. Japan also pledged to outline a new stimulus package in time for a full Group of 20 summit of world leaders next month and said it would inject public money into three struggling banks. And the Swiss government agreed to greater cooperation on tax evasion in order to avoid being put on a blacklist that would hurt the country and lead to job losses, with Austria and Luxembourg making similar concessions. Euro zone retail sales, however, fell more than forecast. The U.S. trade deficit shrank for a record sixth month in a row as both imports and exports fell. Around the world central banks have slashed interest rates and governments have launched stimulus packages to fight what the IMF has called a "Great Recession" of a severity not seen since the 1930s. "We have prepared enough ammunition and we can launch new economic stimulus policies at any time," Wen told a news conference to mark the end of the annual session of parliament. Finance ministers from the G20 are meeting in southern England on Friday and Saturday to prepare for a leaders summit of the group of rich nations and emerging powers on April 2. Washington is urging the big industrialised countries to spend 2 percent of their gross domestic product to boost demand and pull the global economy out of its tailspin, but France and Germany have rejected the U.S. and British calls.
