South Africa's President Cyril Ramaphosa has described as regrettable the announcement by US President Donald Trump that South Africa would not be invited to take part in next year's G20 summit in Florida.

In a social media post, Trump stated that South Africa had refused to hand over the G20 presidency to a US embassy representative at last week's summit in Johannesburg.

Therefore, at my direction, South Africa will NOT be receiving an invitation to the 2026 G20, which will be hosted in the Great City of Miami, Florida next year, he declared.

Members of the G20 do not need an invitation, but can be prohibited from attending through visa restrictions.

Trump boycotted the Johannesburg summit due to a widely discredited claim that South Africa's white minority is victim to large-scale killings and land grabs.

In response, Ramaphosa noted that the US had been expected to participate in the G20 meetings, but unfortunately, it elected not to attend the G20 Leaders Summit in Johannesburg out of its own volition. He highlighted that US businesses and civil society representatives did attend.

Ramaphosa stressed that the presidency instruments were appropriately handed over to a US Embassy official at South Africa's Department of International Relations and Cooperation since the US delegation was absent.

Trump's previous claims of a white genocide in South Africa were rejected by the South African government as baseless and lacking evidence.

Despite efforts to improve relations with the US, Ramaphosa lamented that Trump continued to impose punitive measures against South Africa based on misinformation.

In his latest statements, Trump accused South Africa of being unworthy of G20 membership and announced an immediate halt to all US payments and subsidies to the country.

South African officials urged collective action from G20 members to uphold the integrity of the summit and the rights of its member states.

The recently concluded G20 summit in Johannesburg resulted in a declaration focusing on multilateral cooperation for climate change and economic inequality, despite objections from the US.
