World Bank chief Robert Zoellick said Friday that 2010 would be "a highly uncertain economic year" when much of the stimulus action will run out.

"We have broken the fall of the financial crisis, but it is certainly too early to declare success," he told reporters in Istanbul.

"2009 will continue to be a difficult year, and 2010, when much of the stimulus action will run out, a highly uncertain economic year," he said in a press briefing.

He said the danger today is no longer one of a collapsing world economy but one of complacency.

"If the crisis wanes, there will be a natural tendency to return to business as usual, and it will become harder to convince countries to cooperate in order to address many of the problems that led to this crisis, and the problems that we will face coming out of the crisis," Zoellick said.

"Therefore, we have to seize this moment to press reform," he added.

Zoellick made the remarks ahead of annual meetings of the International Monetary Fund (IMF) and the World Bank in Istanbul which are scheduled for October 6-7.

In its latest World Economic Outlook, the IMF forecast that China will lead Asia out of the economic recession by growing 8.5 percent this year and 9.0 percent in 2010.
