Japanese Prime Minister Kishida Fumio has reiterated his commitment to support Ukraine as Russia's invasion drags on.

Kishida held a news conference shortly after the Group of Seven summit wrapped up on Tuesday in Germany.

He said, "The G7 leaders have agreed to place additional sanctions on Russia to end the invasion of Ukraine as soon as possible. This invasion is trampling on the peaceful world order. We also agreed to continue to strongly support Ukraine, as it fights aggression on the frontline."

Kishida earlier announced Japan's plan to provide a support package worth over a billion dollars to Ukraine and other nations.

Some money will go to offset the global food crisis triggered by the Russian invasion.

Kishida pledged to call on other Asian leaders to unite behind Ukraine. Many have so far remained neutral.

Kishida will chair next year's G7 summit. He officially announced the meeting will be held in Hiroshima.

The atomic-bombed city is Kishida's home constituency.

He said, "From Hiroshima, the G7 leaders will show the world our strong commitment to preventing another nuclear weapons catastrophe, and our firm opposition to any armed aggression."

Kishida will join his G7 colleagues in Madrid on Wednesday for a NATO summit.

Also attending the meeting will be South Korean President Yoon Suk-yeol.

The leaders will discuss security concerns in the Indo-Pacific region in addition to those pertaining to Europe.
