(The AP)--China has been the "most egregious violator" of a worldwide arms embargo, providing Sudan with the vast majority of its small arms and weapons used for mass murder in Darfur province. . .

The arms and also political support are being swapped for access to the African country's oil reserves, according to a report issued on the eve of the Summer Olympics in Beijing. . .

Recognizing fast-developing China's need for energy, William Hartung, a veteran foreign policy analyst and author of the report for the New America Foundation, said the United States might consider energy cooperation with Beijing so it does not rely for oil on Sudan and other repressive regimes. . .
