Ukrainian President Volodymyr Zelenskyy met with two dozen European leaders in London to discuss military aid and protection from Russian aggression.
Zelenskyy urged the United States to expand sanctions on Russian oil to the entire sector, rather than just two companies.
He also appealed for long-range missiles to counter Russian attacks.
The talks come as Ukraine seeks to shield itself from future Russian aggression, should a ceasefire bring an end to the over three-year war.
