Japanese prime minister Yasuo Fukuda left for Europe on Sunday for talks with fellow leaders on the global food crisis as he prepares to host the Group of Eight summit in July, officials said. Fukuda, facing slumping approval ratings, hopes to use the G8 summit of world leaders to boost Japan's diplomatic clout and highlight its efforts to help tackle global warming and food shortages in developing countries. On the first leg of his five-day European trip, he is to arrive in Berlin late Sunday to hold talks with German chancellor Angela Merkel, a government official said.
