Elżbieta Witek made the appeal at a conference of European Union parliamentary Speakers in Brdo, Slovenia on Monday, Poland's PAP news agency reported.
Monday was day one of the two-day event, with the war in Ukraine and its humanitarian fallout dominating proceedings, according to officials.
“We must not let Europe get used to this war,” Witek said in her speech, adding that the continent had a duty to stand up to Russian aggression.
“All countries must be united and stand together,” she added.
‘Putin has lost this war’
Witek said that Russian President Vladimir Putin had been "caught off guard" by how the European Union and the world responded together to his invasion of Ukraine.
“Putin has already lost this war because he hasn’t been able to capture Ukraine,” she told the conference.
Witek also emphasised the need for crisis management and humanitarian aid, especially in frontline countries such as Poland, which were bearing the bulk of the refugee exodus from Ukraine, the PAP news agency reported.
She told reporters that fellow parliamentary Speakers had expressed “admiration and gratitude” for how Poland was welcoming people displaced by the war.
“The government is working with local authorities, charities and the public and doing the best possible job in this difficult situation,” Witek stated.
On the sidelines of the conference, she held bilateral meetings with her counterparts from other EU countries, including Germany’s Bärbel Bas and the Czech Republic’s Markéta Pekarova Adamova, as well as the head of the European Parliament, Roberta Metsola, officials said.
Tuesday is day 34 of the Russian invasion of Ukraine.
Poland on Monday reported it had welcomed 2.32 million refugees fleeing Russia's attack on Ukraine.
Poland’s President Andrzej Duda this month signed into law a measure to offer wide-ranging support to Ukrainians escaping the Russian attack on their country, which began on February 24.
The measure grants them legal residence in Poland and ensures access to education, healthcare and social benefits.
