With six months to go until the Group of 20 summit in Osaka, the basic agenda has been set for discussion on issues of global importance.

But with the G20 process increasingly seen as failing and many leaders likely to arrive in Osaka with severe domestic political problems at home, what will come out of the summit in terms of new agreements to cooperate on issues ranging from climate change to sustainable development to strengthening multilateral free trade and investment is increasingly unclear.

On Dec. 1, as the G20 leaders' summit in Buenos Aires closed, Prime Minster Shinzo Abe outlined the agenda of what will be discussed when the leaders meet on June 28 and 29 in Osaka.
