One example from the long article:
You Xianwen sold his pipe-laying business in Chengdu, in southwest China, this year to move to Addis Ababa, Ethiopia’s capital, to join a startup company with a Chinese partner he had met only online. “Back where I come from we are pretty independent people,” Mr. You, 55, said. “My brothers and sisters all supported my decision to come here. In fact, they say that if things really work out for me, they would like to move to Africa, too.”
Mr. You said he had considered other African countries before settling on Ethiopia, including Zambia. “Luckily I didn’t decide to go there,” he said, explaining that he had been frightened by the recent anti-Chinese protests in that country.
His new business, ABC Bioenergy, builds devices that generate combustible gas from ordinary refuse, providing what Mr. You said would be an affordable alternative source of energy in a country where electricity supplies are erratic and prices high.
