Sikorski, who also serves as a deputy prime minister, spoke to the leaders of Italy, Sweden, the Netherlands, Denmark, Ukraine, Norway, Finland and Turkey on Monday evening, Polish state news agency PAP reported.
NATO officials and representatives from the European Commission and the European Council also took part in the call, according to the Polish foreign ministry.
The conversation took place "shortly after Ukrainian President Volodymyr Zelensky's visit to London," the Polish foreign ministry wrote on the social media platform X.
"Its purpose was to summarize the actions taken so far in support of Ukraine and to discuss progress in the peace negotiations, in light of the recent Russian attacks and ongoing diplomatic initiatives," it added.
Zelensky on Monday held talks in London with British Prime Minister Keir Starmer, French President Emmanuel Macron and German Chancelloer Friedrich Merz.
"The leaders discussed the importance of the US-led peace talks for European security and supported the progress made," Downing Street said.
Polish Deputy Foreign Minister Marcin Bosacki told state broadcaster TVP Info on Monday that Sikorski held a video conference with Starmer and Zelensky after the London talks.
