To the casual observer, the Republic of Zambia's 90 percent approval of U.S. leadership might not make much sense. An increasingly urban and predominantly Christian country, Zambia makes for a receptive audience to Western media, influence and values. Though many languages and dialects are spoken in Zambia, the official language of this one-time British protectorate - both in business and education - is English. And, like many of the countries in Sub-Saharan Africa, Zambia has not been immune from the seemingly endemic African challenges of disease and poverty. The United States has played a prominent role in battling HIV/AIDS in Zambia, being one of the 15 African nations targeted by President George W. Bush's Emergency Plan for AIDS Relief - more commonly referred to as PEPFAR. But while U.S.-Zambian relations have been mostly warm, the West may soon have some serious competition from the East: China. Beijing, as it's done throughout the continent, has committed to several economic and natural resource development programs in Zambia. It remains to be seen whether this relatively new player will affect American approval in the country. Global Top 5s is a monthly feature by RealClearWorld.com powered by Gallup's worldwide research.
