Top 10 manufacturing countries in the world

China’s industrialisation is unprecedented. The last time the ‘king of the manufacturing hill’ got knocked off the throne was when the US surpassed the UK just before WW1. It took the US the better part of a century to rise to the top; the China-US switch took about 15 or 20 years.

The U.S. Defense Industrial Base Is Not Prepared for a Possible Conflict with China..According to the results of a series of CSIS war games, the United States would likely run out of some munitions—such as long-range, precision-guided munitions. This would occur in less than one week in a Taiwan Strait conflict.

These problems are particularly concerning since the rate at which China has been acquiring high-end weapons systems and equipment is five to six times faster than the United States, according to some U.S. government estimates. - https://features.csis.org/preparing-the-US-industrial-base-to-deter-conflict-with-China/
