North Korea Missile Launch: Why Did Kim Jong Un Fire It After Rejecting Seoul’s Dialogue?
North Korea fired a ballistic missile toward the East Sea on Saturday, hours after Kim Jong Un’s sister rejected Seoul’s latest call for dialogue, putting the launch in the context of Pyongyang’s continued rejection of engagement with South Korea. The test also came as tensions were rising over a landmine blast in the Demilitarized Zone that injured three South Korean soldiers.
The missile was launched from the Wonsan area at about 6:30 a.m. local time and flew more than 700 kilometers, according to South Korea’s Joint Chiefs of Staff. South Korean authorities have not said the test was directly linked to Seoul’s dialogue proposal or the dispute over the DMZ blast.
The timing comes after a series of exchanges between the two Koreas over the border incident and Seoul’s efforts to reduce military tensions.
Why Did North Korea Launch the Missile?
There is no public confirmation that the missile was fired specifically in response to the DMZ dispute. However, its timing placed the test immediately after a series of exchanges between Seoul and Pyongyang over the border incident.
South Korea’s military said the Sept. 21 explosion involved North Korean landmines and demanded an apology and responsible measures from Pyongyang. North Korea has repeatedly denied responsibility for deliberately placing the mines.
The United Nations Command has also been investigating alleged North Korean landmine activity south of the Military Demarcation Line. Its public materials say the investigation into alleged mine crossings remains ongoing.
On Friday, Kim Yo Jong rejected Seoul’s accusation and criticized its demand for an apology. Referring to those behind the demand, she described them as “utterly pathetic.” She also said North Korea’s border fortification efforts were intended to sever contact with South Korea.
The missile was launched from the Wonsan area the following morning, but South Korean authorities haven’t publicly linked the test to Kim Yo Jong’s statement.
Seoul Had Continued Calling for Dialogue
The missile test also coincided with government-leadership efforts to cut military tensions and resume talks with North Korea by South Korean President Lee Jae-myung.
Lee said on Oct. 1 that North Korea should join efforts to restore trust and resume dialogue, while his government would continue pursuing measures to reduce military tensions. The statement came as Seoul and Pyongyang were exchanging accusations over the DMZ incident.
North Korea has maintained that it has little interest in engaging with Seoul.
In July 2025, Kim Yo Jong said, “no matter what policy is adopted and whatever proposal is made in Seoul, we have no interest in it, and there is neither the reason to meet nor the issue to be discussed with the ROK.” The statement was carried by North Korea’s state media and reflected Pyongyang’s increasingly distant approach to inter-Korean engagement.
Kim also downplayed growing speculation that she might meet Kim Jong Un in South Korea during the Asia-Pacific Economic Cooperation (APEC) summit, calling it a “delusional fantasy”.
The policy shift followed Kim Jong Un’s move away from the long-standing goal of Korean reunification. North Korea has treated South Korea as a separate and hostile state rather than a partner in eventual reunification.
Missile Launch Follows Earlier Tests
Saturday’s launch came 13 days after North Korea launched two short-range ballistic missiles from the Wonsan area toward the East Sea on Sept. 20. North Korea later said those tests involved a modified version of its Hwasong-11 Ma missile.
South Korean and U.S. intelligence officials monitored the launch of the missile from its early stages and are still studying the missile’s precise characteristics, the Joint Chiefs of Staff said.
The launch follows other military exercises by North Korea that have been observed in recent weeks, such as missile testing and live-fire drills, as well as the introduction of a new warship.
South Korea, U.S. and Japan Monitor the Launch
After the launch, South Korea’s National Security Office convened an emergency security review meeting with South Korean defense officials and the Joint Chiefs of Staff. Officials discussed the country’s posture to respond to the launch and gave instructions to take steps to address the security aspects of the launch.
The South Korean military said it had enhanced its surveillance of the possibility of other launches and would be communicating with the United States and Japan on the matter.
Japan’s government also gave out information regarding the missile to the aircraft and vessels around the trajectory of the missile.
The United States Indo-Pacific Command stated it had been made aware of the launch and was talking with allied countries.
The missile launch took place amid rising inter-Korean tensions, with Pyongyang refusing to engage in dialogue and seeking to strengthen its military capabilities while Seoul is looking for opportunities to engage with Pyongyang.
