Japanese Prime Minister Kishida Fumio is heading for India on Friday to attend the Group of 20 summit.
Kishida has been in Indonesia since Tuesday for a summit with the leaders of the Association of Southeast Asian Nations and other meetings.
He explained the safety of treated and diluted water being released from the damaged Fukushima Daiichi nuclear plant into the sea.
During a brief conversation with Chinese Premier Li Qiang, Kishida also urged China to immediately retract its suspension of all seafood imports from Japan.
In the East Asia Summit on Thursday, the Japanese prime minister called for collaboration to maintain and strengthen an international order based on the rule of law, with increasingly assertive moves by Russia and China in mind.
Kishida summed up that he was able to achieve a new phase of cooperation and collaboration between Japan and the ASEAN countries. He said this is very meaningful for international peace and prosperity.
At the G20 summit in India, Kishida plans to show Japan's stance of proactively contributing to various global issues, based on the results of the G7 summit in Hiroshima in May.
The agenda in India will include global food security, which has been affected by Russia's invasion of Ukraine, as well as development, digital transformation and other international issues.
Kishida also plans to continue explaining the safety of the discharge of treated and diluted water from the Fukushima Daiichi plant with the aim of boosting international understanding for the move.
