Today, over 80 civil society organizations including human rights, corporate accountability, and religious groups from 25 countries, as well as government officials and actor Mia Farrow, submitted an open letter to the United Nations Global Compact (UNGC) in support of a formal complaint against PetroChina, a Global Compact participant. PetroChina, the publicly traded arm of China National Petroleum Corporation (CNPC), is Sudan's largest oil industry partner and has financial links to the regime perpetuating the six-year humanitarian crisis in Darfur which many consider to be genocide.
