Leaders of G-8 countries urged for more stringent international rules on nuclear safety following the disaster at Japan's Fukushima plant. Talking to reporters at G-8 summit in the northern French seaside town of Deauville, French President Nicolas Sarkozy said the members of G-8 wish to get a very high standard of regulation on nuclear safety, that will apply to all countries involved in civilian nuclear energy and which will take safety to the highest levels ever.
