North Korea will change its constitution to better define the border with the ROK and ensure its population learns that South Korea is the “number one hostile country,” physically destroying inter-Korean symbols such as a cross-border rail line and unification monument in Pyongyang, state media reported on Tuesday.

At a Supreme People’s Assembly (SPA) session on Monday, leader Kim Jong Un ordered officials to permanently remove formal cooperation and communication avenues with the South as part of his recent overhaul of unification policies, according to a series of Rodong Sinmun reports.
