Obama: Full economic recovery 'still a ways off'

L'AQUILA, Italy (CNN) - U.S. President Barack Obama said Friday leaders of the industrialized nations have agreed to continue fueling economic growth, while strengthening regulatory measures, but also realize that full recovery is "still a ways off."

Obama listed some of the achievements of the G8 summit this week in Italy as the conference neared the end, and stressed the need for collective action.

In addition, they agreed to stop the spread of nuclear weapons, set goals for reducing carbon monoxide emissions and invest $20 billion in food security. That money is in addition to humanitarian aid already provided.

The G8 countries - Britain, Canada, France, Germany, Italy, Japan, Russia and the United States - have been meeting in L'Aquila, an

earthquake-ravaged town outside Rome.
