Top finance officials from the Group of Seven wealthy democracies are gathering in Germany to discuss ways to strengthen the global economy.

U.S. officials are pressing countries such as Germany that have strong economies and finances to invest more and stimulate their economies. They're also urging European leaders to find a solution to Greece's financial problems that will avoid a messy exit from the euro.

Ahead of the meeting, activists urging more help for poor countries floated large balloons bearing the faces of G-7 leaders next to Dresden's historic Frauenkirche, or Church of Our Lady, urging the meeting to produce more than "hot air."

The gathered finance ministers will also tackle financial regulation and ways to cut off financing for extremist organizations such as the Islamic State group.
