The Serbian International Ministry claimed in March 2020 that there are eighteen nations which have withdrawn their recognition: Burundi, Central African Republic, Comoros, Ghana, Dominica, Guinea-Bissau, Grenada, Lesotho, Liberia, Madagascar, Nauru, Palau, Papua New Guinea, São Tomé and Príncipe, Sierra Leone, Solomon Islands, Suriname, and Togo.
