What did the Europeans want from China? How successful were they

From 1500 to 1800, Mexico and Peru produced something like 85 percent of the world's silver. During that same period at least a third and some people would say over 40 percent of all that silver eventually wound up in China. Now what was going on there and what does it mean? The Europeans of course were not shipping the silver to China as an act of donation or charity. They were getting goods in return, such as silk, porcelain, and later especially tea.

and so they were successful.
