Cambodia’s Prime Minister Hun Sen temporarily suspended new land concessions to private companies in an effort to ease political pressure over an issue that has triggered social unrest and occasional violence. The move came during a visit of a special United Nations envoy on human rights, Surya P. Subedi, who stated that he plans to examine the situation of land concessions and “their impact on the human rights of local communities.” Hun Sen’s action comes less than two weeks after the slaying of a prominent local environmentalist investigating illegal logging.—AP
