From the bilateral perspective the primary question is: How do the two parties conclude their bilateral agreement in light of known or presumed non-party, third-state interest? Specifically, how do they define the endpoint of their boundary in their bilateral agreement? When the bilateral agreement is the first of three agreements associated with a potential tripoint, the two parties have relatively little information regarding the interest or boundary passion of the third states. When the bilateral agreement is the second associated agreement, more information is available to the parties. By the time the third of three associated boundaries is delimited, the parties to the third agreement will already have delimited their boundaries with the third state. As a result of the previous two agreements, the third-state interest should be well known.
