Robert Mugabe has vowed to press on with his
policy of forcing all companies to cede
economic control to black Zimbabweans.
"Indigenisation" was one of his main campaign
issues for last month's election, which he officially
won.
Mr Mugabe, 89, denies opposition claims that the
voting was rigged in his favour.
He says black Zimbabweans need help as they faced
discrimination during white minority rule, which
ended in 1980.
His policy of seizing most of Zimbabwe's white-
owned farms is widely seen as having caused the
country's economic collapse from 2000-2009.
Mr Mugabe says giving black Zimbabweans control of
the business sector is the next step and said the
election result had given him a "resounding
mandate" to do so.
"We will do everything in our power to ensure our objective of total indigenisation,empowerment, development and employment is realised, he told a public rally to mark the annual Defence Forces Day.
Foreign-owned companies are already supposed to ensure they are at least 51% locally owned - a policy which some analysts say has scared off potential investment from abroad.
Reuters news agency reports
that the local operations of foreign-owned mining
companies have already been targeted, while banks
could be next.
On Monday, Mr Mugabe said that his critics could "go
hang", in his first public speech since the disputed
election.
Zimbabwe's economic meltdown halted in 2009 after
a power-sharing government was established and
the local currency abandoned.
Some of Mr Mugabe's allies have suggested that the
Zimbabwe dollar could now be re-introduced but
they have stressed this would not happen soon.
His critics say much of the land seized from white
farmers was either given to his cronies or to people
who lacked the expertise or resources to use it
productively.
He retorts that Western powers are sabotaging
Zimbabwe's economy because of his anti-colonial
stance.
The Constitutional Court is to start considering the
opposition's legal challenge on Wednesday, following
a two-day public holiday.
The nine-member panel of judges has two weeks to
either endorse Mr Mugabe's re-election or order a
rerun.
Mr Mugabe won 61% of the vote in the election on 31
July, with his long-time rival Morgan Tsvangirai on
35%.
The president's Zanu-PF party also gained a
parliamentary majority of more than two-thirds,
winning 160 of the 210 seats.
