Amid worries over a referendum in Greece about the European Union's additional financial support to the country, leaders of the world’s 20 major economies will gather in Cannes, France on Thursday for the 6th G20 Summit.

The two-day summit is expected to address moral hazards in the financial industry, imposing taxes on financial transactions and reforms of the global financial system. Vice finance ministers from the 20 nations previously held a meeting on Monday.

Meanwhile, anti-globalization protesters plan to hold forums and rallies in the French city of Nice during the summit.
