"I find hope in the work of long-established groups such as the Arms Control Association...[and] I find hope in younger anti-nuclear activists and the movement around the world to formally ban the bomb."

New South Korean President Faces Old Challenge


June 2022
By Kelsey Davenport

The new South Korean president has pledged to help strengthen the North Korean economy if Pyongyang denuclearizes, but a recent spate of missile tests suggests that North Korean leaders will continue advancing the country’s nuclear weapons program.

The “door to dialogue will remain open so that we can peacefully resolve” the threat that North Korean nuclear weapons pose to South Korea and the region, Yoon said.

But he did not call specifically for a resumption of negotiations with the North, a move that his liberal predecessor, Moon Jae-in, encouraged in his farewell speech. Moon said on May 8 that he hoped “efforts to resume dialogue between South and North Korea and establish denuclearization and peace would continue” under Yoon.

Moon’s meetings with North Korean leader Kim Jong Un in 2018 helped lay the groundwork for the historic summit between Kim and U.S. President Donald Trump in June 2018. (See ACT, July/August 2018.) Although bilateral dialogue between Moon and Kim yielded important advances, including military confidence-building measures along the Demilitarized Zone, Moon’s progress was hampered by U.S. and UN sanctions that prevented him from pursuing certain inter-Korean projects.

In his farewell address, Moon alluded to external factors as the reason why the inter-Korean process failed to achieve more, saying that there was a “barrier that we can’t overcome with only our determination.”

Even if Yoon were to make a more direct offer to resume talks with North Korea, it might not get anywhere. Kim ordered an aggressive lockdown in response to the country’s first COVID-19 outbreak in May. North Korea has conducted a total of 20 ballistic missile tests this year, including on May 24. That was right after U.S. President Joe Biden met Yoon in Seoul and displayed a somewhat tougher line toward North Korea. Together, these factors suggest that North Korea will continue to focus inward and ignore U.S. and South Korean overtures for negotiations.

South Korea’s recent military advances are likely a partial cause of North Korea’s recent missile activity.

While the Moon administration pursued diplomacy with North Korea, it extended the range of South Korean ballistic missile systems and began investing in other defensive systems, such as more advanced radar to detect incoming missile attacks.

The South Korean Agency for Defense Development announced on May 11 that Seoul completed the development of an advanced radar that can detect and track multiple incoming warheads and differentiate between warheads and other missile debris. The press statement said the system is necessary for “independent, domestic air defense operations” designed to counter the “increasing threat of ballistic missiles.”

South Korean missile developments are just part of a regional arms race that has accelerated over the past several years.

North Korea’s recent missile tests, the majority of which involved short- and medium-range systems, suggest that Pyongyang is responding to a changing regional security environment and to South Korean investment in missile defenses.

The South Korean military confirmed that North Korea tested a submarine-launched ballistic missile (SLBM) on May 7 near the Sinpo submarine base. The missile flew 370 miles. The SLBM appears to be a model that North Korea tested in October, according to the Japanese Defense Ministry. North Korea also launched a missile from near Pyongyang on May 4 that flew nearly 300 miles.

The new South Korean defense minister, Lee Jong-sup, said the security situation on the Korean peninsula is “extremely grave due to North Korea’s advancing missile threats and the possibility of a nuclear test.” He said South Korea’s military would respond “sternly and immediately” to any direct North Korean provocations.

Although North Korean ballistic missile tests violate UN Security Council resolutions, tensions among members of that body prevented any response to the recent tests.

U.S. Ambassador to the United Nations Linda Thomas-Greenfield said it was time for the international community to “stop providing tacit permission and start taking action.”

The council “has stayed silent” because two members argued that restraint will encourage North Korea to “stop escalating and instead come to the negotiating table,” but the opposite has happened, she said during a May 11 council meeting.

Thomas-Greenfield was likely referring to Russia and China, which have opposed new sanctions targeting North Korea, despite its persistent violations of Security Council resolutions.

She called for strengthening sanctions on North Korea, saying the body needs to “speak up now” and not wait for further illegal action by North Korea.

Zhang Jun, China’s UN ambassador, said that “talking is better than coercive measures” and that tightening sanctions now could further escalate tensions.
