"See, big man, politics is harder than you thought," Sikorski wrote on X on Thursday.
The remark came after Trump threatened to cut off federal contracts with Musk's Tesla and SpaceX companies, prompting the tech tycoon to call for Trump's impeachment.
Sikorski's comment also revived a personal spat with Musk who earlier this year called the Polish foreign minister a "small man" and told him to "be quiet" after Sikorski suggested that Ukraine may need alternatives to Musk's Starlink satellite system.
That earlier exchange also drew in US Secretary of State Marco Rubio, and sparked criticism across diplomatic and political circles.
