They added: "The rules-based international order, which we all strive to defend, cannot survive if there is impunity for the deeds that violate it most blatantly – genocide, war crimes, crimes against humanity, and crime of aggression."
The Estonian, Latvian and Lithuanian foreign ministers said that a Special Tribunal for the Punishment of the Crime of Aggression Against Ukraine would complement the role of the International Criminal Court (ICC), which is tasked with collecting evidence, identifying and punishing those responsible for "war crimes, genocide and crimes against humanity" committed in Ukraine.
"While the ICC would prosecute individuals for war crimes, genocide and crimes against humanity, the Special Tribunal’s core responsibility would be the crime of aggression," the Baltic foreign ministers said.
"The key masterminds, instigators and facilitators of this murderous aggression cannot escape justice ...," they stated.
