In geography, 'neighborliness' is measured by how many countries share a land border with a nation. This is a tricky question because the answer is a tie. Both China and Russia share land borders with 14 different countries. China’s neighbors include nations as diverse as North Korea, Vietnam, India, and Afghanistan. Russia, being the largest country by area, stretches from Europe to Asia, bordering countries like Norway, Finland, Ukraine, Georgia, and China itself. If you include maritime borders, the numbers shift, but for strictly land-based borders, these two giants remain the most interconnected nations on Earth, sharing boundaries with a significant portion of the world's sovereign states.
