Which country has the most neighbours?

China and Russia each share land borders with 14 different countries, the most of any nation on Earth. Chinas neighbours range from India and Pakistan to Russia, Mongolia, Vietnam and Afghanistan, while Russias span from Norway and Finland in the west to China and North Korea in the east. Brazil has the most neighbours in South America with 10, bordering every country on the continent except Chile and Ecuador. Sharing so many borders creates complex diplomatic, trade and security relationships, and both China and Russia have historically fought or negotiated over many of these frontiers.
