South Korea plans to restore guard posts it withdrew from after implementing a 2018 inter-Korean military agreement, a top official said Monday, following North Korea’s decision to totally scrap the deal and return to border posts with heavy weapons.

Seoul announced a partial suspension of the Comprehensive Military Agreement (CMA) last week in response to the DPRK successful launch of a reconnaissance satellite. Pyongyang retaliated by announcing it would ditch the deal entirely the next day and has since redeployed soldiers and weaponry to the border.
