[Marvel/MCU] How does Wakanda keep Vibranium in it's borders

I know Wakanda is supposedly a strong nation, but it is quite small and isolated, how does one small African nation keep the entire world from getting at least some of the rarest, strongest and most sought after resource on the planet?

EDIT: I knew they were strong but like everyone else I appear to have underestimated them, interesting stuff!

Wakanda is not just a strong nation, it's a world power and either one of the most technologically advanced, or the most (Latveria gives it competition here). While they are small and could be overwhelmed, there hasn't been a terrestrial force powerful enough to take Wakanda. They have even repelled significant extra-terrestrial threats like Skrulls and even a portion of Thanos' army.

That's how, by bloodying the noses of anyone who comes knocking at their door. Don't underestimate Wakanda, and especially not their King.

EDIT: To give context it took Thanos' army's full force to just breach the Golden City's first wall. Thanos, the guy who crushes planets. The guy who breaks Kings casually.
