Inkqubo yovavanyo lwenqaba ibandakanya uvavanyo olubanzi kunye novavanyo lwesakhiwo senqaba, izinto eziphathekayo, umgangatho we-welding, unyango oluchasayo kunye neminye imiba.

Namhlanje, senze indibano yovavanyo ye-50 yeemitha ezi-3 zonxibelelwano olunemilenze yomthengi waseCongo. Akukho zingxaki zifunyenweyo kwindibano yetyala. Oku kuthetha ukuba iimpahla ziya kuhanjiswa kubathengi kungekudala kwaye sinethemba lokuba banelisekile ngeemveliso zethu. Sijonge phambili kwintsebenziswano yexesha elide kunye nabo.
