Why are American commemorative coins "authorized by the Republic of Liberia?"?

How is it that an African country 'authorizes' these American commemorative proofs? What exactly does it mean that they are 'authorized'? Why is this done?

They are not American commemorative coins, but Liberian coins. They have American themes to try to get Americans to buy them. Many countries cheaply let promoters say they are "legal tender", since the country knows nobody will spend them there, and it is free money to them. The promoters like it since a coin is not a coin unless it is legal tender somewhere, otherwise it is a medal, and there are a lot more coin collectors than medal collectors.
