Michael Sun, the member of the mayoral committee (MMC) for public safety said that he had received abuse from some members of Congress of South African Trade Unions (Cosatu) during the labour federation's nationwide march last week.
During the Joburg CBD leg of the Cosatu march, Sun was asked by the mayor to receive a memorandum and meet representatives from the trade federation.
On Tuesday, Cosatu issued a statement of apology to Sun.
Cosatu National Spokesperson, Sizwe Pamla says after investigations, it was found that their member did indeed make racial slurs towards Sun and have taken the decision to apologise unreservedly.
The remarks were hurtful, patronising and displayed a level of intolerance.— Sizwe Pamla, Cosatu National Spokesperson
Pamla tells Afternoon Drive host, Bongani Bingwa that Sun was called 'Fong Kong' followed by jokes that he knew karate because of his ethnicity.
We felt the comments crossed the line this time around.— Sizwe Pamla, Cosatu National Spokesperson
