So closely is China identified with the [Sudanese] government...that a campaign was waged by the actress Mia Farrow to dub the Beijing Games the "Genocide Olympics." China, a big investor in the energy sector in Sudan, was accused of not using its leverage to put pressure on the government to end the violence in Darfur, where an estimated 200,000 people have died and 2.5 million forced to flee... But...Beijing has made significant changes. It has pressured the [Sudanese] government to accept peacekeepers from the African Union and the United Nations and has sent 315 military engineers to Darfur... In Zambia, anti-Chinese sentiment became an election issue in 2005 after an explosion at a Chinese-owned copper mine... China's ties with the continent today need to be seen in context and not be simplistically labeled as condoning bad practices, including genocide. For its part, Beijing needs to be aware that, especially in the 21st century, business is never simply business. [refers to China National Petroleum Company]
