Finance Minister Mthuli Ncube said on Thursday those charging US dollars have to pay their taxes in US dollars. This includes those applying a three-tier system because their primary currency is the US dollar.
Ncube also said those importing vehicles for personal use, except the disabled, have to pay duty in foreign currency but he gave those who imported vehicles before 22 November six weeks to clear them.
He also listed dozens of products which include foods, vegetables and perfumes, whose duty will be paid in foreign currency.
Mnangagwa and his deputy Constantino Chiwenga said the time for politics was over. It is now time for business and dialogue and ground-breaking ceremonies are kicking off next week.

Chiwenga told the gathering that there were no vacancies and those who were dreaming of ruling this country should forget it and concentrate on developing the country so that it becomes an upper middle income country before 2030.
Mnangagwa’s other deputy Kembo Mohadi did not attend the rally. The President said he had gone to attend his sister’s funeral.
