Relations between Russia and North Korea have reached a “new, strategic level,” Russian Foreign Minister Sergei Lavrov said at the beginning of his trip to Pyongyang Thursday, Russian state media reported.

Speaking at the meeting with his North Korean counterpart Choe Son Hui at the Kumsusan government residence, Lavrov said relations continued to improve after Russian President Vladimir Putin’s recent meeting with North Korean leader Kim Jong Un.

“After the historic summit between President Putin and Chairman of State Affairs Kim Jong Un at the Vostochny Cosmodrome on September 13, we can say with confidence that these relations have reached a qualitatively new, strategic level,” Lavrov said, according to comments published by Tass.

Russia’s top diplomat did not give further details, but the comments will fuel concerns that Russia and the Democratic People’s Republic of Korea are deepening military ties, such as through weaponry supplies, amid the ongoing war in Ukraine. Russia and North Korea deny the allegations.

North Korea’s foreign minister commented that “private meetings of the foreign ministers of the two countries, during which ties of comradeship are strengthened, serve as proof that Korean-Russian bilateral relations, with a long history of friendship, show dynamics of development and are developing with new vitality.”

Western officials expressed concerns that Moscow and Pyongyang were discussing arms deals ahead of, and during, Putin and Kim’s meeting. North Korea denied it would supply weapons to Russia.

Last week, the White House said North Korea recently provided Russia with a shipment of weapons, showing satellite images that it said showed cargo from an ammunition depot in North Korea being loaded onto a Russian-flagged ship before it was taken by rail to a depot near Russia’s southwestern border.

The delivery took place between Sept. 7 and Oct. 1, the U.S. said, as reported by Reuters. The Kremlin rejected the allegations, saying the U.S. did not provide evidence for the claims.

Ukrainian President Volodymyr Zelenskyy said the country’s defense ministry is working to improve communication with troops and to reduce paperwork and bureaucracy.

Ukraine’s Ministry of Defense has gone through a number of shake-ups in recent months, losing several key officials after a procurement scandal and then seeing former Defense Minister Oleksii Reznikov replaced by Rustem Umerov in early September.

Zelenskyy said he met Umerov and his new team Wednesday to discuss how to the make the ministry more agile and responsive.

“I held a meeting with the Minister of Defense of Ukraine – he presented his team, his program. The composition of the ministry has been updated. There are already the first steps to resolve the issues that the military talked about,” Zelenskyy said in his nightly address.

“Reduce bureaucracy, simplify document flow, all procedures, free up commanders’ time for combat work instead of paperwork,” he added.

Zelenskyy said there will be more “digitalization and clarity” in supplies to troops and that there should also “be more readiness for feedback from the military and overcoming the accumulated problems.”

Ukraine released a statement Wednesday condemning Russia’s moves to withdraw from a global nuclear test ban treaty.

A law to revoke Russia’s ratification of the treaty passed through the Duma, Russia’s lower house of parliament, earlier in the day.

“The world is witnessing another provocative step of the aggressor state, aimed at increasing nuclear blackmail,” Ukraine’s Ministry of Foreign Affairs said in a statement, according to a Google translation.

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) “remains one of the key legal elements of the global security architecture in the area of ​​nuclear arms limitation and nuclear non-proliferation,” the statement said.

“Ukraine condemns Russia’s steps to withdraw ratification of the Treaty and calls on the international community to respond accordingly to Moscow’s provocations aimed at harming the object and purpose of the CTBT.”

The treaty was adopted by the United Nations General Assembly in 1996, though eight nations have not ratified it, including the United States.

Russian President Vladimir Putin said the U.S. deciding to supply Ukraine with long-range missiles was “a mistake,” in a news conference in Beijing, as reported by Reuters.

“Firstly, this of course causes harm and creates an additional threat. Secondly, we will of course be able to repel these attacks. War is war,” Putin said.

“But most importantly, it fundamentally lacks the capacity to change the situation on the line of contact at all … This is another mistake by the United States,” he added.

Ukrainian President Volodymyr Zelenskyy said Tuesday that Ukraine had fired the first U.S.-supplied, long-range ATACMS missiles in a nightly address. Zelenskyy had repeatedly asked Washington for the weapons to help in its offensive.

Putin also criticized U.S. involvement in the war more widely.

“A mistake of a larger scale, as yet invisible but still of great importance, is that the United States is becoming more and more personally drawn into this conflict. And let no one say that they have nothing to do with this. We believe they do,” Putin said.
