You could ban/sanction Congolese cobalt; this would increase prices in the short run, while other producing countries adjust supply.

[soared]

Adjusting the supply of cobalt in a country isn't something thats easily adjusted.

[pnako]

Why not? If half of the supply disappears overnight, prices will go through the roof, providing an incentive for current producers to increase output, by increasing effort in their existing mining operations, and more than likely by opening new operations.

If there are sanctions, wouldn't it be the demand being changed and not the supply?

[pnako]

The sanctions would presumably be about cobalt from the problematic regions, so it would not change demand.

But the supply would have to adjust away from the sanctioned region(s) to meet the existing demand.

I'm not sure how much that would help the people of Congo...
