South Africa’s travel and hotel industries have signed a code of conduct designed to protect children against sex tourism, the United Nations Children’s Fund (UNICEF) said today, praising the ethical guide as an enduring legacy of the 2010 World Cup. “The contribution of the travel and tourism industry is vital to help stamp out child sexual exploitation,” said Aida Girma, UNICEF’s representative in South Africa, following the signing of the Tourism Child Protection Code of Conduct in Johannesburg.
