Query: Signatories to the CPPC are required to prevent and punish what?
Context: All signatories to the CPPCG are required to prevent and punish acts of genocide, both in peace and wartime, though some barriers make this enforcement difficult. In particular, some of the signatories—namely, Bahrain, Bangladesh, India, Malaysia, the Philippines, Singapore, the United States, Vietnam, Yemen, and former Yugoslavia—signed with the proviso that no claim of genocide could be brought against them at the International Court of Justice without their consent.
