“Our military is strengthening surveillance as the possibility of an additional nuclear test is rising,” the paper said, citing the restoration last year of previously destroyed tunnels at North Korea’s nuclear test site. North Korea has also secured “substantial amounts of highly enriched uranium” and a “significant level of capability” to miniaturise atomic bombs, a description that remains unchanged in the report since the 2018 defence paper. Japan, on the other hand, was described in the paper as Seoul’s “close neighbour” that “shares values” and “common interests”, according to Yonhap. Such references have been avoided when relations were improved between Seoul and Pyongyang.

Previous defence papers have labelled North Korea as the “main enemy”, “present enemy”, or simply “enemy”, particularly during times of tension. “As North Korea continues to pose military threats without giving up nuclear weapons, its regime and military, which are the main agents of the execution, are our enemies,” the document states, citing Pyongyang’s ongoing weapons development, cyber and military provocations, and its own portrayal of South Korea as an “enemy”. North Korea has continued reprocessing spent fuel from its nuclear reactor and possesses about 70kg (154 pounds) of weapons-grade plutonium, up from 50kg (110 pounds) estimated in the previous report, according to the white paper.Īccording to South Korea’s Yonhap News Agency, approximately 6kg (13 pounds) of plutonium is required to build one nuclear bomb, and the increase in North Korea’s stockpile of the substance is due to operations at the country’s “mainstay nuclear complex” in Yongbyon, north of the capital. The defence paper published on Thursday offered a glimpse into North Korea’s growing number of nuclear weapons and missile stockpiles, as well as its conventional military capabilities, with an estimated North Korean troop strength of 1.28 million active-duty personnel. South Korea has released its latest defence white paper in which it described North Korea as an “enemy” and reports that Pyongyang has increased its stockpile of weapons-grade plutonium by an estimated 40 percent.
