Japanese government sources say the Group of Seven nations are organizing an online summit for Saturday, exactly two years after Russia's invasion of Ukraine started.

The sources also say Prime Minister Kishida Fumio plans to express Japan's intention of continuing to support Ukraine and sanctions against Russia.

Japan and Ukraine signed more than 50 memorandum of cooperation for landmine removals, reviving agriculture and other areas at a conference on Ukraine's reconstruction held in Tokyo on Monday.

Kishida is also expected to stress the need to create international momentum behind achieving lasting peace for Ukraine as soon as possible.

He is likely to call for unity among the G7 members, as some Western countries are said to be feeling donor fatigue.
