On September 2, 2025, according to reports from "International News", Kim Jong Un took a special train schedule to visit China and attended an event commemorating the 80th anniversary of the victory of the China People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War. Accompanied by North Korean Foreign Minister Choi Shan-hee and others. From the images released by North Korean media and KCNA, Kim Jong-un took a train, entered Dandong from North Korea, and finally arrived in Beijing.

According to the North Korean media "KCNA" report, North Korean leader Kim Jong-un inspected the new missile production base on August 31, 2025 before his visit to China. In the report, he introduced the missile production line, and mentioned that "in the last year of the five-year plan, that is, this year, the serial production (large-scale production) of various missiles has been successfully completed and started." This achievement may be the most important core and strategic achievement achieved by the North Korean military industry. This is North Korea's intention to reveal its own missile production base. According to South Korean media, North Korea's large-scale missile production base is believed to be located in Cijiang Province next to the Yalu River on the Sino-Russian border. Cijiang Province is located in the northwest of North Korea. It is named after Cicheng and Jiangjie. It covers an area of about 16,900 square kilometers and is across the Yalu River from Tonghua City, Jilin Province, China.

This is a matter worthy of attention. North Korean media reports introduced the capabilities of the missile production base, from the raw material preparation process to the processing of various missile components, to the professional precision processing and measurement of various complex parts and components, and assembly equipment., constitutes an automated production system. This is an important event before North Korean leader Kim Jong-un visited China to participate in the Victory Day of the Anti-Japanese War. It was obviously intentional and intended to demonstrate to the United States. It can be seen from the report that there are many different missiles in the production workshop, including the basic and improved versions of the KN-23 missile known as the North Korean version of the Iskander missile.

North Korea has not bowed to US pressure and has been trying to build up its armaments. The report was intended to demonstrate North Korea's missile capacity, but also its nuclear strike capability. The ballistic missiles it produces are capable of carrying tactical nuclear warheads. North Korea will not give up its nuclear weapons and missiles in the face of pressure from the United States, South Korea and Japan. The current demonstration led South Korean experts to say: "This inspection is part of a diplomatic and military strategy to reaffirm North Korea's nuclear and missile-centered military prioritization, demonstrate North Korea's military capabilities, and herald military unity with China and Russia, which is essentially a China-Russia-North Korea nuclear strategic alliance."

Demonstrating that North Korea is not a junior nuclear state, it has publicly launched a ballistic missile production line capable of carrying nuclear warheads, emphasizing its status as a "nuclear state" with a large number of nuclear weapons. Now North Korea hopes to prove that it is a country with a strategic position through the demonstration of strength, and hopes to establish a strategic alliance with China and Russia. Now that North Korea wants to play a greater role on the international stage, the demonstration of nuclear capabilities is just a means, a show of cards, and more is to show its military strength, especially conventional forces. The ability to mass-produce ballistic missiles is of great significance.

In the case of the Russian-Ukrainian war, North Korea has provided a lot of support to Russia, not only providing weapons, but also sending troops to participate in the war. North Korea is increasing its assistance to Russia, and has found North Korea's "Pukguksong-2" medium-range ballistic missile launcher in Russia. With North Korea's "Pukguksong-2", Russia has another weapon in its hands that can deter Europe. North Korea's "Pukguksong-2" can make up for Russia's shortcomings in medium-range ballistic missiles, and Russia can directly obtain the "Pukguksong-2" technology from North Korea to accelerate the development of its own similar medium-range ballistic missiles.

Since the start of the war, Russia has fired more than 5,000 ballistic missiles into Ukraine, essentially depleting its stockpile of ballistic missiles. Even though Russia's military factories are at full capacity and missile production is increasing day by day, it is still far from enough to meet demand. But with the support of North Korea, it is different. North Korea's KN23 Hwasong tactical ballistic missile is very similar to the Russian-made Iskander ballistic missile, and has the characteristics of great power. For military targets in the United States and South Korea, its warheads use more powerful warheads.

When the United States first approved the sale of 3350 cruise missiles to Ukraine, the Russian military received hundreds of North Korean-made ballistic missiles. Western countries continue to provide military aid to Ukraine in an attempt to block the attack of Russian troops. At this time, Russia needed foreign aid even more, so North Korea's status was revealed. Now North Korea has not only promised to send 100,000 troops, which was announced by the South Korean president during his visit to the United States, but also provided more arms. This time, the missile production base was revealed to demonstrate its production capabilities.

The West has sent military advisers, firepower experts, intelligence experts, etc. into Ukraine, but it still cannot change the situation that Ukraine is suppressed by the Russian army in all aspects, which has a lot to do with North Korea's contribution behind it. The United States tried to oppress North Korea, and finally shot itself in the foot. Under the heavy pressure, North Korea, which was originally weak, has continuously developed into a military and technological power, which has made the United States seem helpless. The US strategy towards North Korea has long been bankrupt. The reason is that the United States forced it to fail to develop, and ultimately made the United States taste the bitter consequences.
