Question about MP, Bob.

[Dragonsmyth7]

Dear Bob,
I do not know Mp that well to find this answer easily, which why I am asking.  Bob, we all know that MP does 90% of the separation and send the concertrate on China for the final 10% of separation.  They are trying to get the final step don here but so far no dice.  My question is what REEs are in the concertrate that MP sends to China?  Would not send that Concertrate to China hurt China.  I watch a video a long time ago that made a case for that.

So the proportion of the concentrate it produces which is sent to China should
