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 a Russian space official with questions about the rockets.

The meeting with Russian President Vladimir Putin 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.

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.

The decision to meet at Vostochny Cosmodrome, Russia's most important domestic satellite launch facility, suggests that Kim is seeking Russian technical assistance for 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.

Official photos showed that Kim was accompanied by 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, according to South Korea's Unification Ministry.

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 launch facility 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. 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 also brought Jo Chun Ryong, a ruling party official in charge of munitions policies who joined him on recent tours of factories producing artillery shells and missile, according to South Korea.

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.

Kim is expected to seek economic aid as well as military technology. Deputy Foreign Minister Andrei Rudenko said Russia may discuss humanitarian aid with the North Korean delegation, according to Russian news agencies.

An arms deal would violate international sanctions that Russia supported in the past.

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.
