Japan has expressed its willingness to work with the G7 countries to ban imports of Russian oil.
Japanese broadcaster NHK quoted Trade Minister Hagiuda Koichi as saying on Tuesday: "As the international community strengthens sanctions against Moscow, it's in Japan's best interests to cooperate with G7 nations to ensure a stable and secure energy supply, as best it can."
This comes after Russia on Monday released a list of what it calls "unfriendly" countries and places, including Japan.
On Tuesday, Russian-Ukrainian war entered its twelfth day in a row, after Russian President Vladimir Putin announced the launching of military operations on Ukraine, on the morning of February 24.
European, Western and American countries imposed huge economic sanctions on Russia, and those sanctions also targeted Moscow’s leaders, led by President Vladimir Putin and Russian Foreign Minister Sergei Lavrov.
