In answering question #3, President Obama spoke about his thoughts on how many members there should be G8 (should there be G8 +5+5+ etc):

Everyone wants the smallest group, but to include them. something like G20 +1 and its hard to cut smaller nations out.

Transition period, trying to find the right shape and how to include everyone and over the next years we'll see an evolution.

Looking forward to fewer summit meetings. I've only been in office 6 months now and there's been a lot of these. Opportunity to streamline these and make them more effective. We need to make sure they are as productive as possible
