Thomas Peter - Pool/Getty Images China is eyeing off Taiwan's last diplomatic ally in Africa, Swaziland. Last week Burkino Faso became the fourth country in two years to cut ties with Taiwan in favor of China, leaving Taiwan with just one ally in Africa. After signing a document to formalize China-Burkino Faso relations, China's foreign minister spoke of the last country in Africa and Beijing's "sincere hope" that it soon joins the "China-Africa family." China refuses to have diplomatic relations with any country that officially recognizes Taiwan. China is eyeing off diplomatic relations with Swaziland, Taiwan's only official ally left in Africa. Taiwan, a self-ruled island which Beijing considers to be a province of China, has only 18 diplomatic allies left after two countries cut ties in the last month.
