U.S. President Barack Obama will press Group of Eight leaders to consider a growth agenda as they discuss ways to tackle the mounting debt that has threatened the stability of the euro zone.
The economic woes involving the 17-nation single currency could impact other nations, including the United States.
The G-8 leaders are expected to focus on debt-ridden Greece, which could abandon the euro to escape austerity measures.
At a Friday news conference, European Commission President Jose Manuel Barroso said it is important for Greece and other euro zone members to respect commitments.
