Maybe it’ll prod us both. The People’s Republic of China has cut off export of rare earths and the magnets made from them to Japan over Japanese Prime Minister Sanae Takaichi’s recent commentary about Japan’s strengthening resolve to assist the Republic of China in the event of a PRC invasion.

China has begun choking off exports of rare earths and rare-earth magnets to Japan, a potential blow to Japanese companies that use them to produce components for global chip makers, car companies and defense firms.

It really is getting time, and urgently so, for Japan to pull all of its supply chains out of the PRC. Doing so would eliminate nearly all of the PRC’s economic leverage over Japan short of going to war over the sea lines of communication on which Japan depends.

The PRC’s move also should be a serious prod for us to get off the dime and move all of our supply chains out of the PRC. It’s time we proofed ourselves against PRC economic pressure, along with Japan. Nearly half of our economy’s imports flow through portions of those same SLOCs to our west coast.
