RE: China looking at decreasing exports17 Feb 2021 06:37
That's just bluster, the irony of REMs is they are not that rare. The fact that 80% of the refining is currently done in China is down to their low cost labor and low requirements for worker health and safety.
The last time China restricted REMs the USA reopened their old non economically viable refineries to met their own demands. After which China flooded the market with cheaper REM this putting the USA refineries back out of business.
The only power China have here is inflicting a short term supply chain problems.
