Radosław Sikorski made the statement at the 2024 World Economic Forum in Davos, Switzerland, on Thursday.
Poland's top diplomat took part in an event titled Stand Up With Ukraine, and a debate titled Russia: What Next?, alongside the vice-president of the European Union's executive Commission, Valdis Dombrovskis, Romanian foreign minister Luminita-Teodora Odobescu, and Lithuania's top diplomat, Gabrielius Landsbergis, among others.
Sikorski said that a victory for Russia in Ukraine would spark "military conflicts on a larger scale around the world" and "the costs of overcoming them will be much higher than the outlays on support for Ukraine today," according to officials.
Poland's foreign minister urged the West to maintain "firm support for Ukraine," adding that the outcome of the war was "of crucial importance for the future of Poland, the European Union and all the nations in the Euro-Atlantic area."
Sikorski also stressed that "only Ukrainians themselves could decide whether to enter peace talks with Russia," referring to proposals by some Western politicians that Kyiv could begin negotiations with Moscow, Polish Radio's polskieradio24.pl website reported.
Later in the day, the Polish foreign minister met in Davos with Ukrainian war heroes, including "medical professionals, soldiers, and people committed to helping the POW families," officials said.
Sikorski thanked them "for defending Ukraine against the Russian aggressor."
Also on Thursday, Poland's top diplomat held talks with UK counterpart David Cameron.
President Andrzej Duda and Sikorski represented Poland at the 2024 World Economic Forum, which was set to conclude on Friday.
Both stressed that despite a change of government in Warsaw, Ukraine can count on Poland's continued support, polskieradio24.pl reported.
Thursday is day 694 of Russia’s war on Ukraine.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
