It presents not only a crucial lifeline, but also a ‘strategic purpose for a more powerful ally’. The Sino-Korean Friendship bridge (pictured above) spanning across the Yalu River supplies over 90% of North Korea’s trade. This, however, does not mean that China are happy with the relationship. It is just that they prefer a corrupt communist neighbor to the Western World.
