US climate envoy John Kerry has reaffirmed Washington’s confidence in Japan’s decision to release contaminated water from its crippled Fukushima nuclear plant into the sea despite concerns raised by South Korea. Al Jazeera reports that Seoul strongly rebuked the decision, with the foreign ministry summoning the Japanese ambassador and President Moon Jae-in ordering officials to explore petitioning an international court. But Kerry, at a media roundtable on Sunday, said Tokyo had made the decision in a transparent manner and will continue following due procedures. The former US secretary of state added that Washington would closely monitor Japan’s implementation “like every country, to make certain there is no public health threat”.
