Some of the codes which will be discussed and endorsed include the revised International Standards for Laboratories, the revised International Standard for Therapeutic Use Exemptions and international Standards for Testing and Investigations.

South African Minister of Sport and Recreation Fikile Mbalula said that his country took the responsibility to bid for the hosting of this conference to, among others, showcase its achievement in the war against doping in sport.
