Feeding the Dragon: China's Quest for African Minerals
While much of the attention on China’s emergence onto the global economic stage as an industrial powerhouse has focused on the accumulation of its massive trade surpluses, most Western observers probing Beijing’s interest in Africa’s rich natural resources have concentrated on the Middle Kingdom’s seemingly insatiable appetite for energy resources. Africa currently contributes 12 percent of the world's liquid hydrocarbon (oil) production. In 2013, African oil production is projected to rise to 10.7-11.4 million bpd, and by 2018 to 12.4-14.5 million bpd. In 2007, African oil constituted more than 22 percent of the United States' total usage and 28 percent of China’s—the latter case including approximately 60 percent of the Sudan's oil export—compared to the 2006 figures of 9 percent for China, 33 percent for the United States and 36 percent for Europe.

A less mainstream but perhaps more significant issue for Sino-African relations is China’s growing interest in Africa’s rich mineral resources—where Beijing’s shopping list literally runs the gamut, from aluminum to zirconium. Considering China’s dynamic economy and robust growth, its interest in African minerals may well prove in the long run more strategically important in its grand strategy than African oil—especially if China's deals with Central Asian energy exporters prove successful. The minerals sought by China affect every aspect of its economy, from the minerals like titanium needed for producing military aircraft to the iron ore needed to fuel its export of consumer goods, to its surging diamond trade for the country’s growing appetite for luxury items.....
