Considered in this article is the important question of whether the obligation to negotiate imposes an affirmative obligation on a state to seek actively negotiations with the other interested state or states before it can legally engage in certain activities, or whether the obligation to negotiate simply requires the state subject to the obligation to respond favorably when asked by the other state or states to enter into negotiations.
