"China chartered a giant ocean cruise ship, 20 civilian aircraft, four military aircraft and moved 35,860 of its citizens out of danger in Libya as of Wednesday, within a week of starting the process, according to the Chinese foreign minister."
"...They were working in Libya’s oil, rail, construction and telecommunications industries."
"China’s government chartered a fleet of planes to carry them to Shanghai. Quietly, effectively, without fuss, China is evacuating all its workers to safety."
"There are an estimated 50,000 Chinese workers in Nigeria, 35,000 in Sudan, 40,000 in Zambia, 30,000 in Angola, 20,000 in Algeria and thousands more dotted around the African continent. They are the face of Chinese industry, investment, diplomacy and eventually, power."
