Newly inaugurated Zimbabwean President, Emmerson Mnangagwa, may belong to the old guard but he sure knows his onions when it comes to contemporary leadership. The 75-year-old veteran of the liberation struggle laid out a grand vision on Friday to revitalise Zimbabwe’s ravaged economy and vowed to rule on behalf of all the country’s citizens.

Sworn in days after the overthrow of Robert Mugabe, the 75-year-old former security chief promised to guarantee the rights of foreign investors and to re-engage with the West, and said elections would go ahead next year as scheduled.

In a 30-minute speech to tens of thousands of supporters in Harare’s national stadium, Mnangagwa extended an olive branch to opponents, apparently aiming to bridge the ethnic and political divides exploited by his predecessor during his 37 years in charge.

“I intend, nay, am required, to serve our country as the president of all citizens, regardless of color, creed, religion, tribe or political affiliation,” he said, in a speech that also hailed the voice of the people as the “voice of god”.

Behind the rhetoric, some Zimbabweans wonder whether a man who loyally served Mugabe for decades can bring change to a ruling establishment accused of systematic human rights abuses and disastrous economic policies.

He made clear that the land reforms that sparked the violent seizure of thousands of white-owned farms from 2000 would not be reversed, but promised that those who lost property would receive compensation.

To some political opponents, the speech was a welcome contrast with the habitual belligerence of Mugabe and appeared to be drawing on Mnangagwa’s knowledge and understanding of China as a model for running an economy.

“His model has been the Chinese,” said David Coltart, a former education minister and MP from the opposition Movement for Democratic Change.

“He will drive to make Zimbabwe a more attractive investment location, and more efficient, but like China will not tolerate dissent. If you ‘behave’, you will be secure.”

Those skeptical about the new president’s commitment to change question his role in the so-called Gukurahundi massacres in Matabeleland in 1983, when an estimated 20,000 people were killed in a crackdown on Mugabe’s opponents by the North Korean-trained Fifth Brigade.

Mnangagwa was in charge of internal security at the time, but has denied any part in the atrocities.

Many Zimbabweans, especially the ethnic Ndebele who bore the brunt of the Gukurahundi slaughter, will see his appeal on Friday to “let bygones be bygones” as an attempt to gloss over his nation’s darkest chapter.

Some critics have alleged harsh treatment by soldiers of opponents of the military intervention last week – a de facto coup against Mugabe, 93, and his 52-year-old wife Grace.
