China’s special envoy on Darfur will visit Sudan next week, as international pressure on Beijing to do more to end the violence in the region has intensified, AFP reported. Liu Guijin will visit Sudan from February 24 to 27, following a three-day trip to Britain, the Foreign Ministry said. China, which is Sudan’s main overseas supporter and arms supplier, has come under pressure to use its influence to end the human rights abuses in Darfur. Activists have sought to use the Olympic Games as a platform for their criticism of China. Director Steven Spielberg recently resigned from his post as an unpaid artistic consultant to the games’ opening and closing ceremonies.
