During the 2018 North Korea–United States summit, Kim Jong-un promised that North Korea would destroy a missile engine test stand soon. The site was not initially named but was later identified to be the Sohae Satellite Launching Ground by US officials. This pledge was made official as part of the Pyongyang Declaration which Kim and South Korean leader Moon Jae-In signed at the September 2018 inter-Korean summit. On 31 October 2018, South Korean officials visited the site and confirmed it was being dismantled and ready for an upcoming inspection. But in early 2019, after a summit between North Korea and the U.S. ended without an agreement, North Korea began rebuilding of the site. A test took place in December 2019, which confirmed that the site was once again operational.
