Ukrainian President Volodymyr Zelenskyy will attend the Group of Seven summit in person on the final day of the event, which is being held in the western Japanese city of Hiroshima. He will also participate in a session with eight non-G7 leaders, who were invited to the conference.
On Sunday, the final day of the three-day summit, Zelenskyy will take part in a G7 leaders' session on the situation in Ukraine. He is also scheduled to attend a session on peace and security, along with the leaders of the non-G7 nations.
India and some other participating countries have so far taken a neutral stance on the Ukraine situation.
Observers are wondering what positions they will take, when they are actually face-to-face with Zelenskyy.
The G7 leaders released the G7 Hiroshima Leaders' Communique on Saturday. It states that the countries are committed to "intensifying" their "support for Ukraine." It also states that they want to "strengthen disarmament and non-proliferation efforts, towards the ultimate goal of a world without nuclear weapons."
Japan, the chair of this G7 summit, is expected to stress the importance of maintaining and reinforcing the international order based on the rule of law.
Japan's Prime Minister Kishida Fumio is scheduled to meet with Zelenskyy later in the day. Kishida is expected to announce that the Japanese government plans to provide Ukraine with as much assistance as it can.
That includes helping with reconstruction efforts.
He is also likely to express Japan's unwavering solidarity with Ukraine.
