South Korean President Yoon Suk-yeol outlined plans on Wednesday to land a spacecraft on the moon, hours after a North Korean propaganda outlet slammed Seoul’s recent launch of a homegrown rocket as evidence of “double standards.”

Yoon’s remarks came during a visit to the Korea Aerospace Research Institute on Wednesday to congratulate scientists on the successful test-launch of a Nuri rocket last month. Analysts previously told NK News that North Korea could use the South’s space program as further justification for its own rocket development.
