But the plans have yet to be approved by parliament, and there is a vigorous debate in South Africa about how land redistribution would work - and whether seizures could be economically damaging as they were in post-independence Zimbabwe.
Whites, who account for just 8% of South Africa's population, own 72% of the country's individually owned farm and agricultural land, according to the government's Land Audit report in November. The president tweeted about the subject Wednesday night after Fox News host Tucker Carlson discussed it on air.
AfriForum, an organisation that mostly represents white South Africans who have described land expropriation as "catastrophic", travelled to the United States earlier this year to lobby the senate and other officials.
Julius Malema, the leader of the radical opposition Economic Freedom Fighters party, called Trump a "pathological liar" and told him to "stay out of South Africa's domestic affairs". However the same figures show that farm murders are at a 20-year low.
"As a effect, South Africa's northern neighbor's economy collapsed and the country descended into penury and political violence", he said.
Commenting on the process that would be followed to implement land reform, Mabuza said, "everything we do will be done within the confines of the Constitution and within the existing legislative framework". So, facing pressure from rivals in the far-left Economic Freedom Fighters (EFF) party, the ruling African National Congress (ANC) recently made a decision to move towards claiming white-owned farmland without payment. Around 10% of land in white ownership has been transferred to black owners in this way, the BBC said.
Today, almost a quarter-century after the first democratic elections, black South Africans comprise 80 per cent of the population but own just 4 per cent of the country's land, according to the government.
Any attempt by the State Department to influence land policy in South Africa would likely be undermined by the absence of an ambassador to South Africa, one of Africa's top economies.
President Cyril Ramaphosa said during his oral question and answer session in the National Assembly today that the high unemployment rate is a clear signal that the country's economy can not continue to grow at the current rate and that it is a concern.
Most land in the country is owned by the white minority. South Africa currently gets to export many products to the US without duties, under the African Growth & Opportunity Act (AGOA), and some now fear that this access may be curtailed. "The overall sense of where South Africa is now compared to where it was 10 years ago is there is a slower rate of change than people were expecting".
