The announcement of the sanctions comes just hours after former ICC judge Navanethem Pillay was awarded the Nobel Peace Prize.
"President Trump will never allow the International Criminal Court to prosecute Americans," US Secretary of State Marco Rubio said in a prepared statement seen by Reuters.
The statement said the US would use sanctions to “prohibit transactions with this rogue court, hijack its resources, and weaken its ability to operate.”
Supported by Sweden
The ICC rejected the announced US sanctions, calling them in a statement "an attack on the rule of law and on the very foundations of the international legal order."
The European Commission is also sharply critical of Washington's actions.
"It is deeply regrettable that the US has announced its intention to impose sanctions (against the ICC). The EU will work closely with the ICC to ensure that the court can continue its work," the Commission said in a statement.
"Sweden will continue to support the ICC, its independence and its integrity," Swedish Foreign Minister Maria Malmer Stenergard wrote on X.
UN Secretary-General António Guterres said through his spokesman Stephane Dujarric that he was "deeply concerned about the presumed consequences" of the measures.
Support from Netanyahu
Volker Türk, the UN human rights chief, said in a statement that the sanctions were "unacceptable."
One person who praised the American measures, however, was Israeli Prime Minister Benjamin Netanyahu:
"The ICC is not a court. It is a political body that poses a deadly threat to law-abiding democracies around the world as well as to the very basic idea of national sovereignty," Netanyahu wrote in a post on X via his office.
Netanyahu is wanted by the ICC, accused of war crimes and crimes against humanity.
As recently as August, the Trump administration, which believes the court's activities are "politicized," imposed sanctions on two ICC judges.
