China and the African island country of Sao Tome and Principe officially resumed diplomatic relations Dec. 26, AP reported. The ceremony, attended by the foreign ministers of both countries, took place in Beijing. The news comes after Sao Tome and Principe, a former Portuguese colony with a population over around 200,000, broke off relations with Taiwan. China has recently strengthened its efforts to weaken Taiwan's ties with diplomatic allies and defense partners. The issue of Taiwan is becoming increasingly interwoven in Beijing's strategy across the globe, suggesting that China believes the island's status quo is becoming less sustainable.
