China has been making many investments in third-world countries, often in exchange for resource concessions. There is growing concern that some of these projects leave the host country with too much debt–indeed, last December, Sri Lanka sold control of its port of Hambantota to a Chinese state-owned company after falling behind in repaying $1.5 billion in loans from Beijing. Further such situations seem likely. (See interesting article about Chinese investment in Malaysia here.)
China has also been accused of using aid and investment funds to influence other countries’ policies toward Taiwan, an accusation that they unsurprisingly deny…and Taiwan is now down to only one diplomatic ally in Africa, the kingdom of eSwatini (prevously known as Swaziland.) El Salvador, too, has recently dropped diplomatic ties with Taiwan.
