The Consequences of COVID-19 on Chinese Manufacturing

COVID-19, initially spread throughout China, has now spread throughout the world, closing virtually everything. Some countries have gotten the virus under control, while others struggle to get back to normal. Surprising was the speed with which China was able to get the virus under control.
