Coordination essential

With the global economy on the brink of another crisis the maturing G20 must once again rise to the challenge

Since its first summit in 2008, the gathering of the G20 nations has gradually moved center stage in global affairs in the post-crisis era. As fresh financial and trade challenges cut into people's confidence in economic recovery this year, many are hoping for significant breakthroughs among the fanfare in Mexico.

Yet domestic political demands, the acute European debt crisis and concerns about a future global economic downturn have cast a shadow over the possible coordination results of the two-day summit in Los Cabos. Moreover, it will have to overcome accusations that each member does things in its own way on major international issues, and answer questions about its representation and effectiveness.
