In an interview to state media to celebrate the occasion, Zimbabwe President Robert Mugabe confirmed that he intends to run for president in the 2018 general election, Reuters reported.
"They want me to stand for elections, they want me to stand for elections everywhere in the party ... The majority of the people feel that there is no replacement, successor who to them is acceptable, as acceptable as I am," he told the state broadcaster ZBC-TV, according to Reuters.
"The people, you know, would want to judge everyone else on the basis of President Mugabe as the criteria."
In the interview with state television broadcaster ZBC-TV, he also praised US President Donald Trump. The nonagenarian said he agrees with Trump's position on American nationalism and encouraged people to "give him time."
"Well, America for America, America for Americans -- on that we agree," Mugabe said, during the interview, adding "Zimbabwe for Zimbabweans."
It is rare for Mugabe to speak highly of any US leader. Although he said he was "surprised" by President Trump's election, he said he "did not like" Democrat candidate Hillary Clinton.
"I knew she could slap sanctions on us as a legacy," Mugabe said.
Sanctions, such as travel restrictions, were imposed on Mugabe and some of his senior staff from the governing Zanu PF party in 2002. They were extended for another year by President Barack Obama before he left office in January.
Mugabe said he hopes President Trump will "relook (at) the sanctions on Zimbabwe."
Mugabe's recent birthdays have been marked by outlandish celebrations, regardless of the economic hardships the country may be suffering.
In 2009 he celebrated his 85th birthday with a lavish all-day party despite the fact that the country was then gripped by economic and health crises.
At the time, Mugabe's nephew Patrick Zhuwawo said about 100 beasts would be slaughtered for the birthday bash.
This year's celebrations will be held in Matabeleland South province, and event organizers have appealed to local farmers to donate a total of 150 head of cattle for the celebrations, government-owned Herald newspaper reported.
"We have set a target to raise 150 cattle for the event," the newspaper quoted Matobo North legislator Never Khanye as saying.
"We are appealing to well-wishers to do so willingly and not come again tomorrow and say we were forced (to appropriate the livestock)."
