SEOUL--The leaders of Russia and North Korea met at a remote Siberian rocket launch facility for a summit that underscores how the two leaders’ interests are aligning in the face of their separate, intensifying confrontations with the United States.

The two men began their meeting with a tour of a Soyuz-2 space rocket launch facility, at which North Korean leader Kim Jong Un peppered Russian President Vladimir Putin with questions about the rockets.

The meeting came hours after North Korea fired two ballistic missiles toward the sea, extending a highly provocative run in North Korean weapons testing since the start of 2022, as Kim used the distraction caused by Putin’s war on Ukraine to accelerate his weapons development.

The leaders’ decision to meet at Vostochny Cosmodrome, a major satellite launch facility, suggests that Kim is seeking Russian technical assistance in his efforts to develop military reconnaissance satellites, which he has described as crucial in enhancing the threat of his nuclear-capable missiles. In recent months, North Korea has repeatedly failed to put its first military spy satellite into orbit.

Asked whether Russia will help North Korea build satellites, Putin was quoted by Russian state media as saying “that’s why we have come here. The DPRK leader shows keen interest in rocket technology. They’re trying to develop space, too,” using the abbreviation for North Korea’s formal name, the Democratic People’s Republic of Korea. Asked about military cooperation, Putin said “we will talk about all issues without a rush. There is time.”

Putin welcomed Kim’s limousine — brought from Pyongyang in the North Korean leader’s special armored train — at the entrance to the building with a handshake that lasted around 40 seconds. Putin said he was “very glad to see” Kim. Kim’s translator thanked Putin for the warm welcome, “despite being busy.”

The two leaders will sit down for talks after the tour of the cosmodrome, Russian state media reported.

For Putin, the meeting with Kim is an opportunity to refill ammunition stores that the 18-month-old war has drained. For Kim, it’s a chance to get around crippling U.N. sanctions and years of diplomatic isolation. Kim is expected to seek economic aid and military technology, though an arms deal would violate international sanctions that Russia supported in the past.

South Korea’s Joint Chiefs of Staff didn’t immediately say how far the North Korean missiles flew. Japan’s Coast Guard, citing Tokyo’s Defense Ministry, said the missiles have likely already landed but still urged vessels to watch for falling objects.

Kim’s personal train stopped in Khasan, a station on the Russia-North Korea border, early Tuesday where it was met by a military honor guard and a brass band. He was met on a red carpet by regional Gov. Oleg Kozhemyako and Natural Resources Minister Alexander Kozlov, according to North Korean state media and video posted on social media.

Kim said his decision to visit Russia four years after his previous visit showed how Pyongyang is “prioritizing the strategic importance” of its relations with Moscow, North Korea’s official news agency said Wednesday. The Korean Central News Agency said Kim then left for his destination, but it didn’t specify where.

Russian Defense Minister Sergei Shoigu will be part of the Russian delegation, Peskov said.

Kim’s delegation includes Foreign Minister Choe Sun Hui and his top military officials, including Korean People’s Army Marshals Ri Pyong Chol and Pak Jong Chon and Defense Minister Kang Sun Nam.

Other officials identified in North Korean state media photos along his trip could hint at what Kim might seek from Putin and what he would be willing to give.

One is Jo Chun Ryong, a ruling party official in charge of munitions policies who joined him on recent tours of factories producing artillery shells and missiles, according to South Korea’s Unification Ministry.

Also identified in photos were Pak Thae Song, chairman of North Korea’s space science and technology committee, and navy Adm. Kim Myong Sik, who are linked with North Korean efforts to acquire spy satellites and nuclear-capable ballistic missile submarines. Experts say North Korea would struggle to acquire such capabilities without external help, although it’s not clear if Russia would share such sensitive technology.

North Korea may have tens of millions of aging artillery shells and rockets based on Soviet designs that could give a huge boost to the Russian army in Ukraine, analysts say. Kim Jong Un may also seek energy supplies and food. Deputy Foreign Minister Andrei Rudenko said Russia may discuss humanitarian aid with the North Korean delegation, according to Russian news agencies.

Lim Soo-suk, South Korea’s Foreign Ministry spokesperson, said Seoul was maintaining communication with Moscow while closely monitoring Kim’s visit.

“No U.N. member state should violate Security Council sanctions against North Korea by engaging in an illegal trade of arms and must certainly not engage in military cooperation with North Korea that undermines the peace and stability of the international community,” Lim said at a briefing.

The United States has accused North Korea of providing Russia with arms, including selling artillery shells to the Russian mercenary group Wagner. Both Russian and North Korean officials denied such claims.

Speculation about their military cooperation grew after Shoigu, the Russian defense minister, visited North Korea in July. Kim subsequently toured his weapons factories, which experts said had the dual goal of encouraging the modernization of North Korean weaponry and examining artillery and other supplies that could be exported to Russia.
