Poland's Mateusz Morawiecki and Germany's Olaf Scholz also talked about energy security, Polish state news agency PAP reported.
After the meeting, the Polish prime minister told the media that “many leaders are realising the huge errors and risks that underlay previous policies.”
“Today we are holding talks in completely different circumstances … about how to help Ukraine defend its sovereignty,” he added.
Morawiecki warned that Russia’s new offensive in eastern Ukraine would probably turn into “the biggest armoured battle since World War II.”
Ukrainian victory 'depends on bold decisions’
“Whether Ukraine wins and survives depends on bold decisions,” he also said.
The prime minister added that he meant decisions to supply Ukraine with military equipment, including “ammunition and artillery, mainly anti-tank, anti-aircraft and anti-rocket systems.”
Morawiecki stressed that Poland was already delivering such hardware to Ukraine as well as coordinating assistance from the international community.
He said: “I talked to Chancellor Scholz about how Poland and Germany can best help Ukraine together.”
Weapons, sanctions, humanitarian aid
Morawiecki told reporters that the German chancellor “pledged to deliver more weapons to Ukraine." He later tweeted that his talks with Scholtz "were very important.”
He added: “Chancellor Scholz shares the conviction that Ukraine must win this war."
The discussion also focused on “concrete aid to help the Ukrainian state function,” as well as “new sanctions against Russia,” and “ending Europe’s reliance on Russian hydrocarbons," Morawiecki said.
Earlier, Piotr Müller, the spokesman for the Polish government, tweeted that the two leaders had explored “further, effective sanctions against Russia.”
At a policy conference on Monday, Morawiecki had said he would also speak to Scholz about “joining forces to swiftly rebuild Ukraine” after the war, the PAP news agency reported.
Tuesday was day 62 of the Russian invasion of Ukraine.
