China–Russia border

The Chinese–Russian border or the Sino-Russian border is the international border between China and the Asian portion of Russia. After the final demarcation carried out in the early 2000s, it measures 4,209.3 kilometres (2,615.5 mi), and is the world's sixth-longest international border. The China–Russian border consists of two non-contiguous sections separated: the long eastern section between Mongolia and North Korea and the much shorter western section between Kazakhstan and Mongolia.
