Trump's second term has seen relations between the two nations reach their lowest ebb since white-minority rule ended in South Africa in 1994 with Nelson Mandela's rise to power.
Trump has alleged that a "genocide" is taking place against white people in South Africa, that they are facing "race-based discrimination" and their land is being "confiscated" - a claim widely discredited.
The most senior white politician in South Africa has said that President Ramaphosa will have to address the "nonsense" claim during his White House visit.
John Steenhuisen, the leader of South Africa's second-biggest party, the Democratic Alliance (DA), said that Ramaphosa would have to dispel the "myths" that had been "whispered" in Donald Trump's ear so that Washington took decisions based on "the facts and not the fiction".
His views are significant as he is also the agriculture minister in South Africa's coalition government, and keeps close contact with the farmers whom Trump claims are victims whose "land is being confiscated".
"There's not a single farm being expropriated without compensation," Steenhuisen said last week as he prepared to join Ramaphosa's delegation to the US.
Steenhuisen did not say who he believed had done the "whispering" in Trump's ear, but there's speculation he may have been referring to right-wing groups that have been to the US to lobby the Trump administration.
