Distrust of foreigners has increased in South Africa in the four years since a wave of xenophobic violence swept the country. Some 67 percent of South Africans say they do not trust foreigners at all, compared to 60 percent in 2008, survey findings released this week revealed. The survey, by independent research project Afrobarometer and the Institute for Democracy in South Africa, found that nearly a third of the 2,400 respondents would take action to prevent migrants from moving into their neighbourhood and 36 percent would try to stop them from operating businesses.
