5 Longest Land Borders In The World

With waves of immigrants and refugees on the move from Africa and the Middle East to Europe, and from Central America and South America to North America, building walls, fences and other obstacles along land borders between countries is becoming a common thing. The United States has fortified its 3,141 km (1,951 miles) long border with Mexico, and in Europe a wall frenzy is on the go as Croatia and Hungary are now building walls on their borders with Serbia. Slovenia is building a wall on its border with Croatia, while Austria is building a wall on its border with Slovenia – all to stop the massive waves of immigrants and refugees coming from Syria, Iraq and other countries.
So with walls rising along land borders, I thought it would be interesting to list the world’s longest land borders between any two countries
1. Canada – United States: 8,893 km (5,525 miles) – Canada, the world’s second largest country, and the United States (fourth largest) share the longest international border between two countries in the world. The border has 2 segments: From north to south, along Alaska (the largest state in the US) and Yukon in Canada, and from east to west, along 12 other US states and 7 Canadian provinces. Canada shares a land border only with the United States, while the United States shares a second land border with Mexico

2. Russia – Kazakhstan: 6,846 km (4,254 miles) – Russia is the largest country in the world. It has a total length of land borders of just over 20,000 km (12,427), shared with 14 countries. Its longest land border, which is also the world’s second longest land border, is with Kazakhstan, its neighbor to the south and the world’s 9th largest country

3. Argentina – Chile: 5,300 km (3,293 miles) – Argentina is the 8th largest country in the world, and while Chile is much smaller than Argentina (about a quarter of its size) – its long narrow form puts their shared border as the third longest in the world

4. China – Mongolia: 4,677 km (2,906 miles) – China is the third largest country in the world, and with a total land borders of 22,147 km (13,761 miles) shared with 16 countries, it’s bound to be listed here a few times. China’s longest border is with its neighbor to the north: Mongolia, which also shares one of the world’s longest borders with it’s neighbor to the north: Russia

5. India – Bangladesh: 4,053 km (2,518 miles) – India is the 7th largest country in the world and third largest in Asia. It has borders with 7 countries. But the longest border is with the small country of Bangladesh, which is around 5% of the size of India. The reason for that is that the India-Bangladesh border is splitted to 199 different segments, created by the 92 Bangladeshi enclaves inside India, and 106 Indian enclaves inside Bangladesh
