The South African government has defended its decision to deny entry to the Dalai Lama, amid charges it is bowing to pressure from China. The Tibetan spiritual leader was due to attend a peace meeting in Johannesburg this week, along with fellow Nobel laureates Desmond Tutu and FW de Klerk.

Speculation is rife in the local media that the government caved in to pressure from Beijing
