China has long been the sole major ally and trading partner of the reclusive nation, but heightened tension has resulted in an economic slowdown in relations.

Nowhere is this slowdown more apparent than on the 880-mile long border between the two countries. Although trade continues, half-finished buildings and an eerie sense of abandonment showcase the strained ties.
