Hours after Chinese President Xi Jinping touched down in close neighboring
Russia for a three-day visit, Japanese Prime Minister
Fumio Kishida started a surprise trip to Ukraine early on Tuesday.
The competitors' long-running diplomatic offensives coincide with the simultaneous summits.
At the nation's capital, Kishida will meet with President Volodymyr Zelenskyy.
As the leader of Japan and the chairman of the G-7, he will "demonstrate solidarity and
unshakable support for Ukraine" during his visit to Kyiv,
the Japanese Foreign Ministry said in a statement announcing his arrival in the Ukrainian capital.
