In an interview with Poland's PAP news agency, Sikorski, who also serves as a deputy prime minister, said: "If (Nawrocki) has the relations he says he has and has influence over Donald Trump, the time has come to use it."
"The point is to prevent a Yalta 2 for Ukraine and to strengthen the presence of American troops in Poland," Sikorski added.
He said he had been making this appeal regularly for several months.
The interview was published on Monday.
That same day, Trump suggested it might be time for Ukrainian President Volodymyr Zelensky "to get somebody else to negotiate" on Kyiv’s behalf, adding that Russia has been "fine" with regards to Ukraine, the Reuters news agency reported.
Zelensky, meanwhile, described some US decisions on the war, including delays in arms shipments and restrictions on intelligence sharing, as "hard to explain."
Sikorski told PAP that Poland supported Trump’s stated aim of ending Russia’s war against Ukraine, but believed that "a more effective method would be to increase pressure on the aggressor, not on the victim of aggression."
He noted that Secretary of State Marco Rubio had said the Graham bill, which would allow Trump to impose steep tariffs on major buyers of Russian oil and gas, would be suspended for only 60 days.
Asked about Polish Prime Minister Donald Tusk’s warning that Russia was preparing "something big," Sikorski said: "When we say 'something big,' we don’t mean an invasion, because they are not capable of that."
He did not rule out a further escalation of hybrid warfare, citing Russian attempts last winter to disrupt a Polish hospital and a heating plant.
He said he was "a little surprised" that Nawrocki was downplaying threats raised by allies, and noted that the president had vetoed SAFE, an EU scheme providing low-interest loans to member states for defence investment.
Asked whether a win for Marine Le Pen in France would embolden Poland’s far right, Sikorski replied: "It seems that we already have a Polish Marine Le Pen in the presidential palace."
He said the French politician wanted to cut European aid to Ukraine, while Germany’s far-right AfD sought the withdrawal of US troops from the country, and questioned whether Polish right-wing parties really supported their allies carrying out such plans.
On the still-pending decision on a US military base in Poland, he acknowledged that it was up to Washington but would prefer it to come before the US midterm elections because "politicians are more inclined to give" before voters go to the polls.
Turning to support for Ukraine, Sikorski said urgent humanitarian aid was needed ahead of the cold months and that the help the Polish government provided last winter should be doubled.
He also said that Poland was "not among the NATO countries with spare Patriot missiles" and could only join calls for others to share them.
On using frozen Russian central bank assets for Ukraine, with Belgium blocking a deal, the Polish foreign minister said: "I wouldn’t count on an agreement before winter."
Asked about the recent unrest in France and whether it could fuel anti-immigrant sentiment among Polish nationalists, Sikorski said Poland was in control of migration and accused the previous Law and Justice (PiS) government of having "dehumanised" migrants while letting them in.
