Point and serves as a placeholder for a possible future boundary. Therefore, joint zones are included in the accompanying table.
Joint zones do not have identifiable endpoints, and are therefore of relatively little assistance in identifying tripointlacations or understanding tripoint status. For that reason, the presence of joint zones was disregarded when determining the appropriate tripoint classification for potential tripoint with associated joint zones. Instead, with two exception, only the tripoint in formation available from the non-zone boundary agreements associated with each tripoint was considered. The first exception was for the Chaina-Japan-South Korea tripoint which was included in the table solely on the basis of the Japan-South Korea Joint Development Zone. The second exception was for thr potential “tripoint” among Barbados Guyana,Trinidad and Tobago, and Venezuela,which is classified as a conflicting tripoint on the basis of the relationship between the Trinidad and Tobago-Venezuela boundary and the Barbados-Guyana Cooperation Zone.
Of the potential tripoints with associated joint zones,one is a conflicting tripoint, seven are uncertain tripoints,and one is a probable tripoint.
