"Serious challenges remain," they cautioned in a closing statement. "While growth is returning, the recovery is uneven and fragile, unemployment in many countries remains at unacceptable levels, and the social impact of the crisis is still widely felt," according to the document from the Group of 20 major industrial and developing nations.
Summit participants navigated a careful course between Obama, with his emphasis on growth, and fellow leaders such as German Chancellor Angela Merkel who advocated spending cuts and even tax increases.
"Advanced economies have committed to fiscal plans that will at least halve deficits by 2013 and stabilize or reduce government debt-to-GDP ratios by 2016," according to the statement. The gross domestic product (GDP) measures the value of all goods and services, and is considered the best gauge of economic health.

A White House statement said the G-20's Toronto agreement carries through with existing stimulus programs while recognizing that deficit-reduction "needs to be calibrated ... and tailored to national circumstances."
The G-20 document came at the end of three days of economic summitry.
