Three minutes before the stock market opens here in the US and all major Indices around the world are heading lower. China has now publicly hinted they may HALT the purchase of US Government Debt, (i.e. Treasury Bonds) and have said the U.S. "Must leave North Korea alone."
Knowing the U.S can and will attack North Korea's nuclear weapons program facilities and its long range missile development facilities unless North Korea voluntarily agrees to denuclearize, China is now openly siding with the illegal development of nuclear weapons and long-range missiles by North Korea.
The United States response to China was simple "We will do what we have to do with North Korea."
