Chinese Premier Wen Jiabao on Sunday said Beijing would ease some bans imposed on Japanese food imports over a nuclear crisis as leaders of Japan, China and South Korea held a trilateral summit. For Japan the three-way meeting was an opportunity to address the concerns of its neighbours over its handling of world's worst nuclear crisis since Chernobyl 25 years ago, triggered by the March 11 earthquake and tsunami. Tokyo's neighbours have been concerned by the leak of radiation from the crippled Fukushima Daiichi plant and its impact on food safety across the region. For Japan, the summit was an opportunity to secure the easing of import restrictions.
