European leaders are hoping for debt crisis breakthrough as they gather Thursday to sign off on measures meant to boost economic growth in the eurozone.
Many believe Europe hasn't taken strong enough action to ease its financial trouble. Investors also fear Europe's problems will eventually hurt the world economy, including the United States.
Leaders seemed optimistic heading into Thursday's summit and are expecting to agree on new economic policies.
"I expect that there will be a decision on a further step toward rebuilding the economic and monetary union," European Commissioner for Economic Affairs Olli Rehn said.
"We also need concrete decisions on a short-term stabilization of financial markets, especially sovereign debt markets," he added.
Investors will be watching for signs of a clear strategy to deal with the debt crisis in Europe, including a possible plan for international eurobonds.
