South Africa coalition strained after trade envoy fails to visit US

South Africa's main coalition partners are embroiled in a spat over how to respond to looming tariffs from a hostile Trump administration, after the smaller party said the president's aide was denied a U.S. visa to negotiate with Washington.

The Democratic Alliance said on Tuesday that the United States had formally rejected President Cyril Ramaphosa's chosen interlocutor, Mcebisi Jonas, and had denied him a diplomatic visa in May.

The DA provided no evidence for the claim, which its leading international relations official Emma Louise Powell repeated in a statement on Thursday.

Presidency spokesperson Vincent Magwenya, in a response, did not say whether Jonas had been denied a visa.

"President Ramaphosa has not had a need for Mr. Jonas to visit the United States on urgent business," he said in a statement.

He added that Jonas had been working in the background with the trade and foreign ministries. Since his appointment in April, the government has not mentioned Jonas as having met with any U.S. officials.

He was not part of a delegation that travelled to Washington in May, a trip during which U.S. President Donald Trump assailed Ramaphosa in the Oval Office with false claims of mass killings of white South African farmers.

Magwenya declined to comment further when Reuters contacted him on Thursday. Jonas did not immediately respond to a text message requesting comment. The U.S. embassy in Pretoria did not immediately respond to a request for comment.

Washington's 30% tariff for South Africa kicks in on August 1. Central bank governor Lesetja Kganyago warned on Wednesday that it could trigger 100,000 job losses.

Ramaphosa's African National Congress is furious that the white-led DA, which like Trump has criticised South Africa's racial diversity policies, made an independent visit to the United States earlier this year to plead the country's case to U.S. politicians.

The erstwhile enemies forged an unlikely coalition after the ANC lost its outright majority in elections last year. But they have clashed over equity laws, education policy and the budget, which the DA has held up on grounds of corruption and waste.

Ramaphosa fired a DA deputy minister for failing to get permission to take part in the U.S. trip.

"As the ANC continues to engage with ... the likes of Russia and Iran, the DA will continue to ... engage with the international community of democracies," Powell said in a statement defending the DA's U.S. trip on Thursday.
