| Haha, it means that one of the borders could be disputed. For example, it's determined that the DRC and Tanzania share a land border - however, you cannot walk from one country into the other, as Lake Tanganyika is right in the middle of it. See the above comments for the France issue, and the Zambia one involves an intersection of borders, much akin to the Four Corners in the US. Many sources consider Colorado and Arizona to border each other, even if it is only at one point; so that's why I included Botswana. |
