He issued the tweet after a segment on an American television show, Tucker Carlson Tonight, examined the Land Expropriation Without Compensation proposal. To add to that, statistics are not kept by race - so there is no guarantee that all of those killed were white.
It's unfortunate that South Africa's land policy is being prejudged while the process is still underway, Francois Groepe, a deputy governor of the Reserve Bank, said in a Bloomberg TV interview at Jackson Hole on Thursday, regarding Trump's tweet.
The move also cuts into the platform of the EFF party, headed by firebrand Julius Malema, who has made land expropriation without compensation his clarion call.
Mandela said Trump should be focusing on his own domestic challenges and "the fundamental issues that the "Black Lives Matter" campaign raises".
South Africa totally rejects this narrow perception which only seeks to divide our nation and reminds us of our colonial past.
"The constitution has not yet been changed and ... the ANC has been following a willing-buyer-willing-seller module to redistribute land".
The South African government is not seizing land of white farmers. It was not immediately available for comment on Trump's tweet. In April, Identity Evropa, a white supremacist group, posted pictures of a protest they staged in front of the South African embassy in Washington, D.C., against "the slaughter of White farmers". "I didn't know that "threats" to South African farmers was a major story on RT".
The US is one of South Africa's biggest trading partners. Black farmers own just 4% of the relevant land.
The United States warned South Africa on Thursday that seizing land without compensation risked sending the country down the wrong path, deepening a spat over Pretoria's efforts to fix a glaring racial disparity nearly 25 years after the end of apartheid.
Trump's framing about the South African government "seizing land from white farmers" omits critical context and leaves the wrong impression.

Mr Ramaphosa has said any land reform will be conducted without an impact on economic growth or food security.
Estimates vary but the consensus is that most privately owned land remains in white hands, making it a potent symbol of the wider economic and wealth disparities that remain two decades after the end of white-minority rule.
"The reason for the issue being put back on the table is that for a long time there has been a lack of progress", says Vandome.
ANC officials have said unused land will be the main target.
When Ramaphosa became party leader in February, the ANC was split. As a concession, he has since pushed forward efforts on land reform in an attempt to capitalize on widespread dissatisfaction at the current situation. Debate over the issue has grown ahead of next year's election.
Dr. Johan Burger, a researcher for South Africa's Institute for Security Studies, told the Australian Broadcasting Company fact-checkers that farm attacks may be partially motivated by the isolation of farmers; because their land is further away from neighbors and police stations, they may be easier to rob.
Their stance is that section 25 of the constitution is fine and suggest that ways to effect land reform is for the government to release urban land in their ownership and build housing for the people.
