China produces 80 percent of the world's tussad (wild silk) and 50 percent of the world's supply of silk yarn. Italy and France produced better finished products than China. And the most prized silk of all is Chinese silk yarn made into fabrics at Italian mills.
A third of China's raw silk, brocade and satin comes from the Zhejiang Province, the "Land of Silk." Describing the city of Suzhou, near Zhejiang in the Jiangsu Province, in 1276, Marco Polo wrote: "They have vast quantities of raw silk, and manufacture it, not only for their own consumption, all of them being clothed in dresses of silk, but also for other markets.
