In what is one of Wallström's first international trips since becoming Foreign Minister, she will tomorrow meet with President Poroshenko as well as the Ukrainian Prime Minister Arseniy Yatsenyuk and Foreign Minister Pavlo Klimkin.
"My message today is that Sweden will continue to support Ukraine", she said, "through continued aid, and by politically condemning Russian aggression and by pushing for continued sanctions against Russia."
Activists on "Maidan" also reminded Sweden's new Foreign Minister that her predecessor, Carl Bildt, was one of the first EU ministers to give them his support, Swedish Television news reports.
"I'm the first to admit that", Wallström responded, "I think he should have credit for it, that he was the first one to say something through which the Ukrainians could feel strong support."
Wallström will also meet women's groups and LGBTQ organisations while in the Ukrainian capital.
