Yes, but it should be emphasized how dependent "Reserves" are on both exploration work, and current assumptions about future mining/refining/market conditions.

China's secret to having most of the world's Reserves may be that they bored a lot more test holes (to actually know "the rock in >THIS< spot is X% tungsten") than anyone else, then made some more-optimistic assumptions.

Ehhh, it could go both ways (as far as over-optimism)

On one hand, historically there's a lot of sparsely populated land; that makes it easier to both do exploration and partition off the land.

Also there is China's more central economy planning; i.e. if it's truly worth it they are more willing to do something about relocating people while 'selling it better' (which is again helped by the sparse populations where they are looking.)

That is, unless you are saying they fudged the sampling....

However, that's still other a weird reversal of the geopolitical playbook; that is, one could argue that the -smartest- thing the US/EU can do, is to import whatever natural materials they can, until the 'clock' runs out, then the native materials can be extracted (even at the 'ecologically correct' cost.)
