ZHANG YIN, who made her money in the paper industry, is the wealthiest businesswoman in the world, according to Hurun Report, a Chinese magazine. Its ranking of the 20 richest self-made women (those who earned their money) combines its own findings with those of Forbes and the Sunday Times. Over half of the women in the top 20 are of Chinese origin, perhaps because of a communist ethos of gender equality, perhaps because previous generations of Chinese left so little wealth to be inherited. The richest non-Chinese is a Spaniard, Rosalía Mera, one of three on the list to have made her fortune in fashion.(The Economist)
