Pretoria now faces a formal diplomatic decision with clear legal machinery behind it: whether to declare United States Ambassador Leo Brent Bozell III persona non grata, a step permitted under the Vienna Convention on Diplomatic Relations without any obligation to explain the reasoning. The question has moved from political rhetoric into the terrain of statecraft, as senior figures in the governing party and Parliament argue that the ambassador’s public conduct has crossed the boundaries the Convention sets for foreign envoys.
Under the Vienna Convention, diplomats are required to respect the laws and regulations of the receiving state and to refrain from interfering in its internal affairs. Supra Mahumapelo, chairperson of Parliament’s Portfolio Committee on International Relations and Co-operation, invoked those obligations directly in a forceful statement defending South Africa’s sovereignty.
“The Vienna Convention on Diplomatic Relations requires diplomats to respect the laws and regulations of the receiving state and not interfere in its internal affairs. Public commentary that undermines the decisions of our Constitutional Court and questions domestic transformation policies aimed at redressing apartheid inequalities is incompatible with diplomatic norms,” Mahumapelo said.
His intervention places the matter squarely within parliamentary oversight of the country’s foreign relations, and adds institutional weight to calls for the government to assess whether the ambassador’s conduct remains compatible with the responsibilities of diplomatic office.
The ruling party has taken the same position. In an interview with CAJ News Africa on Tuesday evening, African National Congress national spokesperson Mahlengi Bhengu-Motsiri expressed serious concern about Bozell’s public statements, arguing that no foreign diplomat holds the authority to dictate how South Africa governs itself.
“No foreign representative has the authority to dictate to the South African people how their country should be governed,” she said.
Bhengu-Motsiri warned that the ambassador’s pronouncements raise concerns about diplomatic protocols and the principle of non-interference in the internal affairs of sovereign states. She stressed that the decision on any expulsion rests with the government, which must act in the national interest, while making clear that South Africa’s sovereignty cannot be compromised to satisfy another country. She also challenged attempts to use investment as leverage over domestic policymaking, insisting that foreign capital must respect the country’s constitutional framework and transformation agenda.
“Investment must not become an instrument of political pressure to compel a sovereign country to abandon its democratically determined policies,” she said.
Meanwhile, the opposition Economic Freedom Fighters have condemned Washington’s actions in parallel terms, accusing the United States of weaponising its diplomatic and economic power to interfere in South Africa’s sovereign affairs. Their response came after the latest US announcement of visa restrictions against unnamed South African officials, which the party rejected as an attempt to punish the country for pursuing an independent foreign policy and implementing measures aimed at redressing the inequalities inherited from colonialism and apartheid.
“The EFF has consistently maintained that South Africa must determine its own domestic and foreign policy without receiving instructions from any other foreign power,” EFF spokesperson Sinawo Thambo said in a statement.
Thambo argued that the visa restrictions form part of an escalating campaign to pressure Pretoria into abandoning its transformation agenda, and maintained that Washington has no democratic mandate to determine how South Africa addresses the consequences of apartheid, particularly the land question. The party insisted the government can no longer dismiss the dispute as a mere diplomatic disagreement, warning that sovereignty requires a firm response to foreign pressure.
The controversy has reignited a wider Pan-African question about how long African countries should tolerate foreign representatives making pronouncements on domestic legislation, judicial decisions and foreign policy without facing meaningful diplomatic consequences. For many across the continent, the dispute reflects an unequal international order in which powerful nations expect access to markets and resources while questioning the policies of African governments. As coverage of the standoff continues, further reporting is available at https://iol.co.za/news/africa/2026-10-15-hands-off-south-africa-washington/ and the debate in Pretoria is expected to turn on whether the government concludes that the Vienna Convention’s established mechanism should now be used.
