Mashruuca Daaweynta Leachate Angola

Faahfaahinta Mashruuca

Xalka halka joogsiga ah ee ay bixiso Jiarong waa mid lagu dabaqi karo dareeraha iyo daaweynta kale ee adag ee biyaha wasakhda ah. Xalku wuxuu ahaa mid waxtar u leh macmiilka Angola si loo yareeyo qulqulka biyaha wasakhda ah. Sidoo kale, tayada daloolku waxay la kulantay heerka dheecaanka dareeraha deegaanka.
