Countries that occupy only islands (such as Australia, Japan, the Philippines, Sri Lanka, and Iceland) may have no neighbors, although some island countries do share a border with a country (such as the United Kingdom and Ireland, Haiti and the Dominican Republic, and Papua New Guinea and Indonesia).
China Has 14 Neighboring Countries. China is the third largest country in terms of area (if we count Antarctica) and its lands dominate the southeastern part of Asia. This location (next to many small countries) and the 13,954 miles (22,457 kilometers) of border brings it to the top of the list as having the most neighbors in the world.
