World

the land boundaries in The World Factbook total 279,035.5 km (not counting shared boundaries twice); two nations, China and Russia, each border 14 other countries

note 1: the total is actually misleading in terms of accuracy, since one cannot accurately measure every river meander along a boundary; a number rounded slightly higher - to 280,000 km - makes more sense and has been coordinated with and approved by the US State Department

note 2: 46 nations and other areas are landlocked, these include: Afghanistan, Andorra, Armenia, Austria, Azerbaijan, Belarus, Bhutan, Bolivia, Botswana, Burkina Faso, Burundi, Central African Republic, Chad, Czechia, Eswatini, Ethiopia, Holy See (Vatican City), Hungary, Kazakhstan, Kosovo, Kyrgyzstan, Laos, Lesotho, Liechtenstein, Luxembourg, Macedonia, Malawi, Mali, Moldova, Mongolia, Nepal, Niger, Paraguay, Rwanda, San Marino, Serbia, Slovakia, South Sudan, Switzerland, Tajikistan, Turkmenistan, Uganda, Uzbekistan, West Bank, Zambia, Zimbabwe; two of these, Liechtenstein and Uzbekistan, are doubly landlocked

note 3: worldwide, some one-quarter of interior (non-coastal) borders are rivers; South America with 43% leads the continents, followed by North America with 32%, Africa with 30%, Europe with 23%, and Asia with 18%; Australia has no interior national river borders
