"Kichina! Kichina!"
In rural Tanzania, the locals have a habit of referring to any poor-quality product as "kichina," which, in Swahili, roughly means "a thing of China." Whenever something they use breaks or gets damaged when they think the product should not be, they just shrug and casually blurt out, "well, it's kichina." It is not particularly targeted toward Chinese products though; in fact, the saying is used for all products, whether or not the product is from China. The connotation, however, is pretty clear: it goes without saying that Chinese products, as they have elsewhere, acquired a negative reputation in Tanzania.
