North Korea revealed Thursday it conducted a three-day testing spree of advanced weapons systems including ballistic missiles armed with cluster-bomb warheads, as Chinese Foreign Minister Wang Yi arrived in Pyongyang for his first visit since 2019—underscoring escalating tensions and shifting diplomatic alignments in Northeast Asia.
North Korea’s official Korean Central News Agency reported the tests lasted three days starting Monday and included demonstrations of anti-aircraft weapons, purported electromagnetic weapons systems and carbon-fiber bombs.
One test proved the surface-to-surface tactical ballistic missile called Hwasongpho-11 Ka, which is tipped with a cluster bomb warhead, can “reduce to ashes any target” covering an area of up to 7 hectares (17 acres), KCNA reported.
The weapons demonstrations occurred as South Korea detected multiple short-range ballistic missiles launched Wednesday flying 240 to 700 kilometers (150 to 434 miles) before falling into the sea, marking North Korea’s fourth and fifth known ballistic missile tests this year.
KCNA reported the latest tests included demonstrations of cluster-munition warhead systems mounted on the nuclear-capable Hwasongpho-11 Ka ballistic missiles, which resemble Russia’s Iskander missiles in their design for low-altitude, maneuverable flight to evade missile defense systems.
Kim Jong Sik, a general who oversaw the tests, called the electromagnetic weapon system and carbon fibre bombs “special assets” for North Korea’s military, according to KCNA. The revelation suggests North Korea is developing increasingly sophisticated conventional weapons alongside its nuclear program.
Wang Yi’s arrival Thursday for a two-day visit marks Beijing’s most senior diplomatic engagement with Pyongyang since the COVID-19 pandemic severely curtailed bilateral exchanges. Chinese Foreign Ministry spokesperson Mao Ning called Wang’s upcoming visit—scheduled over April 9 to 10—“an important move to advance bilateral ties.”
Wang’s last publicly known visit to North Korea as China’s foreign minister was in late 2019, following reciprocal visits by the two countries’ top leaders earlier that year. The timing of his visit, coinciding with North Korea’s weapons tests, signals China’s intent to reassert influence over its traditional ally as Pyongyang has strengthened ties with Russia.
The diplomatic choreography comes against a backdrop of heightened regional tensions. On Tuesday night, Jang Kum-chol, first vice minister at the North Korean foreign ministry, said South Korea would always remain the North’s “most hostile enemy state.” He derided South Korea as “world-startling fools” engaged in wishful thinking over a recent statement by Kim Yo-jong, the influential sister of North Korean leader Kim Jong-un.
South Korea responded with alarm to the weapons tests. The presidential office in Yongsan convened an emergency security meeting, according to Yonhap News Agency, urging Pyongyang to end such tests.
Jang Do-young, a spokesperson for South Korea’s Joint Chiefs of Staff, told reporters at a briefing that the military was analyzing the launches while sharing information with U.S. and Japanese counterparts, but declined to provide specific assessments about the North’s claims of progress in its military capabilities.
Japan’s Defense Ministry reported none of the weapons fired Wednesday entered waters within its exclusive economic zone, while the U.S. military stated the North Korean launches on Tuesday and Wednesday posed no immediate threat to the United States or its allies.
The weapons tests represent a significant escalation in North Korea’s military capabilities. According to lawmakers briefed by South Korea’s National Intelligence Service on Monday, the engine test was likely related to an effort to build a more powerful solid-fuel intercontinental ballistic missile that can carry multiple nuclear warheads.
Wang’s visit comes as the Biden administration continues its policy of diplomatic engagement combined with pressure on North Korea to abandon its nuclear weapons program. The timing could complicate U.S. efforts to coordinate with regional allies on North Korea policy.
According to Yonhap News Agency, coordination between North Korea and China could influence broader regional diplomatic dynamics as Beijing seeks to maintain influence over its traditional ally.
In February, Kim Jong Un indicated there is “no reason” North Korea and the United States cannot “get along well” if Washington recognizes North Korea as a nuclear-armed state and abandons its “hostile” policy against Pyongyang. However, recent weapons tests and hostile rhetoric suggest Pyongyang is strengthening its position ahead of any potential diplomatic outreach.
North Korean leader Kim Jong Un suspended virtually all diplomacy with Seoul and Washington following the collapse of his nuclear talks with former President Donald Trump in 2019, and has since accelerated the development of nuclear-capable missiles that threaten U.S. allies in Asia as well as the U.S. mainland.
The cluster-bomb warhead tests mark a concerning development for regional security. Cluster munitions scatter numerous smaller bomblets over wide areas and are banned by over 100 countries under the 2008 Convention on Cluster Munitions due to their indiscriminate effects and long-term danger to civilians.
As Wang prepares for meetings with North Korean leadership, his visit represents Beijing’s attempt to maintain diplomatic channels with Pyongyang while regional tensions continue to escalate through weapons testing and inflammatory rhetoric.
