World finance leaders see threats ahead for global economy, especially a Greek debt default

The world's financial leaders see a number of threats facing a global economy still on an uneven road to recovery, with U.S. and European officials worrying that Greece will default on its debt.

Finance ministers and central bank governors ended meetings in Washington on Saturday determined to work toward what International Monetary Fund officials called "a more robust, balanced and job-rich economy."

Seeking to resolve Athens' debt crisis, Greek Finance Minister Yanis Varoufakis held a series of talks with other finance officials on the sidelines of the meetings. The focus now shifts to Riga, Latvia, where European Union finance ministers meet next week.

The head of the European Central Bank, Mario Draghi (DRAHG'-ee), says it is "urgent" to resolve disputes between Greece and its creditors.
