China's pollution probem on ree cannot be ignore for too long so prices has to increase across the world
There are too much impact on the environment and water supply so my guess is Chinese government will have to crack down on ree operations. Rare earth will increase in price down the road from today.
This is logical also for China to have a stable pricing for rare earth so all miners in China can have a decent wages. It will cost much more to fix the pollute water later on anyway. Problems of the environment do not just go away.
