The North has already put in place posts along a six-mile stretch along a narrow tributary of the Yalu River, which marks the border between North Korea and China, and has also built a road to guard the area.
Meanwhile China has built a massive barbed wire and concrete fence along parts of its 880 mile border with North Korea.
No word from the open border activists about any of this. Oh no, they're quick to jump on the USA, but you won't hear any massive outcry about the poor Korean refugees fleeing a country far worse than Mexico, El Salvador etc. Hypocrites.
