The party in a letter to the ministers on Monday said South Africa’s contribution to the AU quadrupled by 2014, adding that there was possibility of the contribution increasing over the next few years.
The party, therefore, demanded clarity on who authorised the funding contribution and what the funds would be spent on.
Meanwhile, former Nigerian President, Olusegun Obasanjo, while addressing the AU Summit, proposed that levies in airfare, hotel accommodation and hospitality and even SMS taxes be charged on South Africans.
However, Sandy Kalyan, DA Legislature, said the proposal has no basis as such taxes would place a further burden on an already overtaxed and economically strained population.
She said South Africa cannot afford the taxes, because the country was already facing a looming economic crisis.
Kalyan said the economy has only grown at less than 2 per cent over the past five years.
