Nobel prize-winning economist Paul Krugman (L) is greeted with flowers as he arrives at a government guest house in Hanoi on May 22, 2009. Krugman is attending a meeting with Vietnamese economists and officials over recommendations on Vietnam's development strategy in world economy and post-financial crisis. The worst of the global economic crisis is probably over but any early recovery is unlikely due to massive debts worldwide, said Krugman earlier in the week.
