Group of 20 to Urge Quicker Action in Europe WASHINGTON - The rest of the world has a message for Europe, whose intensifying debt crisis will dominate the agenda at the Group of 20 summit meeting next week in Mexico: Tell us how you will end this. In recent days, world leaders have made increasingly blunt public statements about Europe as concerns about a Greek exit from the euro zone and Spain's ability to repay its debts have worried markets and weighed on global growth, already at a historically sluggish pace. Lael Brainard, the Treasury under secretary for international affairs, said during a news conference on Friday that "ensuring our European partners are escalating their response" and getting European leaders to articulate their plan to end the market strife would be a top goal of world leaders at the meeting. But experts said they expected few concrete, actionable agenda items to come from the conference, which formally begins on Monday in Las Cabos. Nevertheless, Group of 20 leaders plan to urge European leaders to describe their plans to calm the markets, including progress on their bailout funds and on building a closer financial union. In advance of the meeting, world leaders have made increasingly sharp public statements on what is widely viewed as a too-little, too-late response by Europe. Julia Gillard, the prime minister of Australia, and Lee Myung-bak, the president of South Korea, co-wrote a letter saying, "We need a clear message from Europe that it is taking decisive steps to stabilize and strengthen its banks and that it is focused on restoring growth." The two leaders also warned about the "human cost" of the economic malaise and uncertainty. Speaking at an event at the Peterson Institute for International Economics in Washington on Thursday, Robert B. Zoellick, the outgoing president of the World Bank, said that Europe's string of "a day late and a euro short" policies had only made the crisis more costly. Treasury Secretary Timothy F. Geithner echoed those comments, speaking at the Council on Foreign Relations in Washington on Wednesday. "If you wait to move on these things and you let the market get ahead of you, then you increase the cost of the solution," he said. Mr. Geithner said Europeans had a "big incentive" to provide as much clarity and guidance to the world as they could. He said that his European counterparts were not "minimizing risk," as they had done in the past. "They are not telling us they have a whole bunch of time," Mr. Geithner said. At the summit meeting, the world's leaders are expected to push Europeans to finish work on their bailout funds, and bolster their abilities - allowing them to lend directly to banks, not just countries, for instance. Officials in the United States and other countries are also expected to urge Europe to focus on growth by delaying some austerity measures, investing in infrastructure and carrying out labor market reforms. Precautionary funds that the rest of the world has pulled together to guard against a deterioration of market conditions in Europe will also be on the agenda. This winter, economists at the International Monetary Fund determined that the world needed an additional $1 trillion to ensure that all countries would maintain access to the debt markets at sustainable rates in the event of another financial crisis or spell of economic contraction. European leaders agreed to bolster their bailout funds by about half that amount. That opened the door for the I.M.F. to raise $430 billion in pledges from its member countries. Big, cash-rich emerging-market nations expected to provide much of the financing declined to name their precise contributions this spring, and were widely expected to announce how much they would be willing to offer at the Group of 20 summit meeting. But some countries, including Brazil and China, are expected to continue holding off on making their contributions. For one, the emerging-market countries want to speed internal reforms at the monetary fund to give them more say within the institution. Second, some officials in big developing economies have expressed reluctance to giving more money to the I.M.F. to help stem the European crisis if the Europeans are not using more of their own resources and acting more decisively. At a news conference on Thursday, Gerry Rice, an I.M.F. spokesman, denied that the fund-raising drive had stalled. "Discussions have continued with the various donors," he said. It was never expected the package would be completed with every detail fixed by this time.
