The gathering took place on the sidelines of a EU–African Union summit marking 50 years of Angola’s independence.
European leaders meeting in the Angolan capital discussed a US peace plan for ending Russia's war in Ukraine, Polish state news agency PAP reported.
"There is full European consensus that these proposals need careful consideration. Some points are unacceptable. Above all, no agreement can in any way weaken Poland, Europe or our collective security," Tusk told reporters.
He emphasised the EU’s commitment to supporting Ukraine and ensuring "a fair and lasting peace."
He warned that a victory for Russia and a defeat for Ukraine would "pose a direct threat" to Poland.
"I hope this is understood across Europe," he said.
Tusk also stressed the importance of NATO unity, pledging to "do everything to ensure the United States is on our side in this process."
He cautioned that peace terms "must not favour the aggressor," including proposals that would limit Ukraine’s military capabilities.
European leaders were also considering further sanctions on Russia and the potential use of frozen Russian assets to support Ukraine, Tusk said.
The talks in Luanda followed an earlier meeting in Geneva, where US, Ukrainian and EU officials discussed the 28-point US plan designed to bring an end to Russia's nearly four-year-old invasion of Ukraine.
