Ifri and the Canon Institute for Global Studies are launching a series of policy papers presenting the analyses of senior Japanese researchers on how the triple disasters that hit the archipelago last March have impacted Japan's economic, environmental and energy policies as well as country's crisis management system.

This first paper deals with a number of the economic challenges that have arisen following the earthquake, tsunami and nuclear crisis, and considers the direction that future economic policies in Japan should take.

This paper looks into natural gas pricing in the post-financial crisis market and, in particular, examines the question whether the oil-linked gas pricing system has outlived its utility as global gas markets mature and converge more rapidly than expected and as large new resources of unconventional gas shift the gas terms-of-trade.

After two years of existence at the Heads of State and Government level, the Group of 20 (G20) has reached a turning point. In this new context, a number of questions need to be addressed-in particular, as to how to ensure the transition from a crisis management body to a global governance committee. How can the G20 solve the legitimacy problems inherent to its structure and nature? How can it address its representativeness deficit? What should be the exact mandate of the Group and how can this mandate be achieved?

The European defence sector generates €86 billion annually - and that is only taking into account the 2009 turnover of the European defence industry for the three areas - aeronautics, land forces and naval forces.
