Both witnessed the opening of the World Cup last month.
The International Relations Director General, Ayanda Ntsaluba, told journalists at a press conference on Thursday that Mugabe was invited as he was a recognised head of the unity government in that country.
“He is the head of the government and is recognised by the United Nations, African Union and SADC…he is not under any sanctions,” said Ntsaluba.
He was responding to criticism from some human rights groups surrounding Mugabe’s invitation.
Ntsaluba also said a further 17 “eminent persons”, including former Zambian President Kenneth Kaunda and Zimbabwean Prime Minsiter Tsvangirai were expected to be among the dignitaries who will grace the event.
Ntsaluba said all logistical arrangements were being finalised for the visiting dignitaries. “All arrangements are being finalised to ensure the successful attendance of the Heads of State and Government and other VIPs to the closing ceremony, including accommodation, seating arrangements, security, transport, logistics and protocol arrangements.
At least 15 African Heads of State are expected to grace Sunday’s World Cup final , expected to be the biggest ever football spectacle.
Mugabe will join Kenyan President Mwai Kibaki, Mozambican President Armando Guebuz, Gabon President Ali Bongo Ondimba, Comoros President Ahmed Abdullah Mohamed Sambi, King Letsie of Lesotho and King Mswati of Swaziland who were all believed to have confirmed their attendance, to mark the closure of the tournament, the first ever on African soil.
The Presidents of Malawi, Burundi, Ghana, Togo, Burkina Faso and Djibouti are also expected to be present.
Brazilian President Luiz Inacio Lula da Silva, on a state visit to South Africa, as well as delegates from both Spain and the Netherlands, are also expected to attend.
Ntsaluba, said many of the Heads of State were also expected to attend the 1Goal Education Summit, to be hosted by President Jacob Zuma and FIFA President Sepp Blatter, ahead of the final match on Sunday.
However, no decision had been reached on whether former Nobel Prize winner Nelson Mandela would attend.
If the 91-year-old statesman does, he would likely be the one handing the trophy to the World Cup winner.
“All our guests and soccer lovers should expect an African feast of all times, and will treasure the memories of this World Cup for many years to come,” said Ntsaluba
He said government was encouraged by the success of the tournament, adding that visitors will go back home with “fond memories” of the country.
Spain will take on Netherlands in the final match. Organisers say the closing ceremony to precede it will be “more youthful and a bit more technologically advanced” than the traditionally African ceremony which opened the tournament on 11 June.
