I previously wrote that Kevin Rudd might go to the G-20 despite (or, perhaps, because of) the election.
He is now using the Syrian crisis as an excuse to attend the G-20.
But this shows he does not understand the raison d’être of the G-20 which is about economics and finance, not security and defence. The official G-20 website states:
The Group of Twenty (G20) is the premier forum for international cooperation on the most important issues of the global economic and financial agenda.
The objectives of the G20 refer to:
1. Policy coordination between its members in order to achieve global economic stability, sustainable growth;
2. Promoting financial regulations that reduce risks and prevent future financial crises;
3. Modernizing international financial architecture.
The Syrian crisis is not part of the G-20′s mandate. Security responses are the function of the G-8 (which Australia is not a member of) and the United Nations Security Council. There is no UNSC meeting being held in Saint Petersburg.
Rudd is just using Syria as an excuse to quit the country to go to an international meeting.
