North Korea’s Kim back home from Russia, where he deepened ‘comradely’ ties with Putin

Kim Jong-un visited Russia, meeting with President Putin and Defence Minister Shoigu to discuss boosting defence ties. They visited military sites to see advanced weapons systems, and Kim offered "full and unconditional support" to Putin. South Korea warned Russia against military cooperation with North Korea, which could have a "very negative impact" on relations. Kim is seeking to bolster his nuclear arsenal to win concessions from the US and boost his military credentials at home.

North Korea said on September 19 that leader Kim Jong-un has returned home from a trip to Russia where he deepened “comradely fellowship and friendly ties” with President Vladimir Putin.

During Mr. Kim's six-day trip to Russia, his longest foreign travel as a leader, the two countries said they discussed boosting their defence ties but didn't disclose any specific steps. Foreign experts speculate the two countries, both locked in confrontations with the West, were pushing to reach arms transfer deals in violation of U.N. Security Council resolutions.

The official Korean Central News Agency said Mr. Kim's train crossed a border river on Monday morning but didn't say whether he headed to the capital, Pyongyang, or elsewhere inside the country. Before travelling to Russia, Mr. Kim made several visits to his munitions factories, triggering speculation that he intended to check on the production of arms to be shipped to Russia.

While travelling through Russia's far eastern region, Mr. Kim met Mr. Putin at Russia's most important space launch centre before visiting military sites to see some of Russia's most advanced weapons systems such as nuclear-capable bombers, fighter jets and hypersonic missiles.

In live comments during their meeting last Wednesday, Mr. Kim offered “full and unconditional support” to Mr. Putin. KCNA later said Mr. Kim and Russian Defence Minister Sergei Shoigu also met and discussed expanding “strategic and tactical coordination” between the countries' armed forces.

Many outside experts say Mr. Kim would supply ammunition to refill Russia's drained inventory in the second year of the war in Ukraine in return for receiving Russian technologies to modernise his nuclear weapons arsenals. U.S. and South Korean officials have warned that Russia and North Korea would face consequences if they go ahead with such weapons transfers deals in violation of U.N. Security Council resolutions.

Other experts say Mr. Kim would end up getting food and economic aid because Russia is reluctant to share its sensitive, high-tech weapons technologies with other countries.
