The Group of 20 leaders ended their two-day summit on Sunday, with Prime Minister Fumio Kishida stressing that he has secured the understanding of other nations on the safety of the release of treated radioactive water from the crippled Fukushima nuclear plant.

While China has claimed the water discharge into the sea will harm the maritime environment and human health, Kishida said at a news conference after the conclusion of the summit in New Delhi that Tokyo will make efforts to build "stable" relations with Beijing.

Kishida, however, added Japan will continue urging China to swiftly lift a blanket ban on Japanese seafood imports, which was quickly imposed after the beginning of the water release in late August, asking Beijing to take "responsible" actions.
