Ukraine’s foreign minister pressed top diplomats from the G7 industrialized nations on Wednesday for support as Russian air strikes caused rolling blackouts across the country.

Speaking at a meeting on Ukraine and defense cooperation, Andriy Sybiha warned that Kyiv faces a “very difficult, very tough winter” and called on allies to pressure Russia and raise the cost of its aggression. The meeting was attended by U.S. Secretary of State Marco Rubio and other G7 counterparts.

Canada announced new sanctions targeting 13 individuals and 11 entities linked to Russia’s drone program, while the United Kingdom pledged 13 million pounds ($17 million) to repair Ukraine’s energy infrastructure and support heating, water, and humanitarian needs. Rubio made no immediate announcements but said on social media that discussions focused on strengthening Ukraine’s defense and seeking a “durable and lasting peace.”

The G7 meeting comes amid fluctuating U.S. support under Republican President Donald Trump, whose policies toward Ukraine have alternated between urging territorial concessions and backing Kyiv’s ability to reclaim occupied areas. U.S. arms transfers to Ukraine have been inconsistent, and Trump has at times sought a ceasefire deal between President Volodymyr Zelenskyy and Vladimir Putin, with little progress.

Zelenskyy has requested 25 Patriot air defense systems from the U.S., while Russian missile and drone strikes continue to target Ukraine’s energy grid and eastern stronghold of Pokrovsk.

Canadian Foreign Minister Anita Anand said Ottawa is “doing whatever is necessary to support Ukraine” and emphasized that countries enabling Russia’s war will face consequences. The G7 discussions also included ministers from Australia, Brazil, India, Saudi Arabia, Mexico, South Korea, South Africa, and Ukraine.

The two-day meeting in southern Ontario takes place amid broader tensions between the U.S. and traditional allies over defense spending, trade disputes, and uncertainty over Trump’s foreign policy priorities.
