Who would buy Germany's colonies before 1914

Who would buy Germany's colonies if the German Empire tried to sell them before the First World War?

Britain would probably bid aggressively, largely to prevent a rival power from acquiring strategically useful colonial territory.

A bidding contest is likely in which Britain participates to keep the colonies out of other hands. The United States might also show interest, but Britain would have especially strong reasons to control who gained new bases and influence. The answer makes the value of a colony relational: preventing a rival acquisition can matter as much as the direct economic return.
