This is possibly a bigger deal than MP Materials DoJ floor price as Lynas is the major Western supplier to the Japanese market. The DoJ deal was likely the catalyst in a floor price being included in this one, and puts a lot more pressure on China's long standing control of rare earth market prices.

Also comes on top of Lynas's 10 year license renewal for the Malaysian processing plant.

I'd say this is good in a trade diversity strategic sense. Being sole supplier is great if you can be the price setter but when you depend on price support, it means you're captive to the market in question, and US strategic behaviour right now is not helpful.
