Wednesday’s announcement did not include an expected constitutional revision to formally designate South Korea its principal enemy and codify new national borders.
While the moves were likely a pressure tactic, it is unclear how they will affect ties with South Korea since cross-border travel and exchanges have been halted for years.
North Korea’s military said it will “completely cut off roads and railways ” linked to South Korea and “fortify the relevant areas of our side with strong defence structures,” according to the official Korean Central News Agency (KCNA).
The military called its steps a “self-defensive measure for inhibiting war and defending the security” of North Korea. It said that “the hostile forces are getting ever more reckless in their confrontational hysteria.”
It cited what it called various war exercises in South Korea, the deployment of US strategic assets and its rivals’ harsh rhetoric.
South Korean officials earlier said North Korea had been adding anti-tank barriers and reinforcing roads on its side of the border since April in a likely attempt to boost its front-line security posture and prevent its soldiers and citizens from defecting.
