Here is Jim Rickards latest interview with Epoch Times. It is chock full of discussion about major monetary system change coming. Here are some quotes related to China and the US dollar from the article.
"Epoch Times: Can China supply the world with a reserve currency?
"But to be a reserve currency means that countries that have reserves have to invest it in something, so you need a deep liquid pool of investable assets. China does not have that. There is no Chinese bond market. There are a few Dim-Sum bonds and a few other things, but there is no Chinese government bond market to speak of, and it would take 10 to 15 years to develop one."
