President of Ukraine Volodymyr Zelenskyy held a telephone conversation with Japanese Prime Minister Shigeru Ishiba.

"I congratulated him on his election as head of government and thanked the Japanese people for all the large-scale humanitarian and financial aid totaling $12 billion, which allows saving thousands of lives," Zelenskyy said on the Telegram channel Wednesday.

The head of state said he also informed the Japanese head of government about Russia's massive shelling of Ukraine's energy infrastructure on Christmas night.

Zelenskyy thanked Japan for its willingness to work for establishing a just and lasting peace as soon as possible.

"I am grateful for the Japanese government's decision to give Ukraine another $3 billion secured by frozen Russian assets and for additional aid for energy equipment and construction of bomb shelters," he said.

The interlocutors agreed to meet to continue the dialog.
