G7 nations have emphasised the need for robust "security arrangements" to ensure a ceasefire between Ukraine and Russia, warning Moscow to follow Kyiv in agreeing a truce or face further sanctions.

Moscow doled out permanent entry bans on Foreign Minister Iwaya Takeshi and eight other top officials and business leaders in retaliation for Japanese sanctions on Russia for its invasion of Ukraine.

The list includes Japanese Foreign Minister Takeshi Iwai, the president and representative director of carmaker Isuzu Shinsuke Minami, and Shohei Hara, senior vice president of the Japan International Cooperation Agency (JICA).
