PRETORIA, March 11 (Reuters) - South Africa's government called in the new U.S. ambassador to the country to explain himself over "undiplomatic remarks," foreign affairs minister Ronald Lamola said on Wednesday.
Conservative activist and writer Leo Brent Bozell III arrived in Pretoria as U.S. President Donald Trump's envoy last month.
Diplomatic relations between the two countries have soured during Trump's second term in office.
Trump has criticised South Africa's Black Economic Empowerment policies to address the legacy of centuries of racial inequality and its genocide case at the World Court against Israel, a close U.S. ally. Israel strongly rejects South Africa's genocide case over its military campaign in Gaza.
At a conference on Tuesday, Bozell waded into controversy by arguing that South African liberation chant "Kill the Boer" amounts to hate speech, despite local courts ruling that it does not.
Bozell said: "I'm sorry, I don't care what your courts say. It's hate speech."
Lamola told a press conference that Bozell's comments were viewed as undermining the country's judiciary and history.
Another senior foreign affairs official Zane Dangor said Bozell had "apologised and expressed regret ... in terms of what happened yesterday".
Lamola said Bozell's "role as a guest is to support us to build one nation, ... he must not take us back to a polarized society along racial lines."
South Africa seeks to project a non-aligned foreign policy stance. Trump has accused it of taking "aggressive positions" towards Washington and its allies.
