There's no reason to merge Congo and Zaire: the 2 countries are mentionned in Fantastic beasts and even now it's not the same country :

• Democratic Republic of the Congo = Zaire
• Republic of the Congo = Congo

See this text : The Republic of the Congo (French: République du Congo; Kongo: Repubilika ya Kongo; Lingala: Republiki ya Kongó), also known as Congo-Brazzaville, Little Congo, or simply the Congo, is a state in Central Africa. It is bordered by Gabon, Cameroon, the Central African Republic, the Democratic Republic of the Congo (formerly known as Zaire), the Angolan exclave province of Cabinda, and the Gulf of Guinea.
