Sikorski, who is also deputy prime minister, told reporters ahead of the talks in Atlanta that he would raise the issue with Russia’s Sergei Lavrov during the two-day talks in Georgia.
He would repeat the appeal he made at the UN Security Council: "Sergey, tell your boss that's enough. Five years of this bloody war, it should be brought to an end."
The agenda of the meeting includes freedom of navigation, access to food and energy.
Sikorski stressed that Poland had a lot to contribute on all three fronts.
He highlighted the safety of shipping and critical infrastructure in the Baltic Sea, as well as the failure of Ukrainian and European grain to reach countries such as Egypt.
He described this as another reason why Russia’s aggression must end.
He also portrayed Poland as one of the world’s fastest-modernising countries in the energy sector, arguing that the war had shown how secure supplies at competitive prices could not be taken for granted.
Asked about a Reuters report on Friday that Pentagon officials, including Deputy Secretary of Defense Elbridge Colby, had in recent weeks urged several European NATO members to soften their rhetoric towards Russia, Sikorski challenged the idea of "responding politely" to Moscow's attacks.
He pointed to the killing of more than a dozen passengers at a railway station in Dnipro that morning, the bombing of cities and ballistic missile strikes on heating and power plants.
Lithuania, Latvia and Estonia were among the countries named in the report.
As for Lavrov’s presence, Sikorski acknowledged that the invitation had put Poland in an "uncomfortable" position.
Warsaw wanted Russia to respect the rules of the international organisations it belonged to, he argued: "If you are a member of a club, you have to behave like a gentleman, and some, unfortunately, can’t."
He also confirmed plans to meet US Secretary of State Marco Rubio, the host of the talks, to discuss several issues that were not public.
The UK has invited Poland to take part in next year’s G20 work, Sikorski added, while Warsaw is seeking similar invitations from South Korea and Mexico, which will hold the subsequent presidencies.
He acknowledged that Russia was unlikely to welcome the prospect.
