China's military has been increasing the strength and number of its forces along its 880-mile border with North Korea as Pyongyang's military provocations cause the US and its allies to think long and hard about military action against the rogue regime.
A report from The Wall Street Journal says that China has established a new border-defense brigade, implemented 24-hour video surveillance of the border, and constructed bunkers to protect from possible nuclear or chemical attacks.
China conducted a live-fire drill in June and July with helicopter gunships and armored infantry units, including a simulated battle with artillery, tanks, and helicopters, according to The Journal. The nature of these military exercises goes beyond securing a border, and they mimic fighting a nuclear-armed adversary.
While China and North Korea exist on paper as allies, Sim Tack, an expert on North Korea at Stratfor, a geopolitical-analysis firm, previously told Business Insider that China would not likely defend Pyongyang from a US-led attack and instead try to prevent or dissuade the US from taking such a step.
Still, a US-led attack on North Korea remains unlikely. South Korea's new liberal government has sought to pursue engagement with its neighbor, and the US would ultimately need its support for such a campaign. From a purely military point of view, North Korea's artillery and nuclear arms hold too many civilians in Seoul at risk.
