Russia's Lavrov meets North Korea's Kim, slams 'dangerous' US policy

Russian Foreign Minister Sergei Lavrov met with North Korea's Kim Jong Un on Thursday, after slamming US policy towards the nuclear-armed state as "dangerous".

Lavrov hailed North Korea as a "close neighbour and long-time partner" in a meeting that lasted a little over an hour, Russia's foreign ministry said in a statement.

The veteran envoy's two-day visit is expected to lay the groundwork for a trip to the country by Russian President Vladimir Putin, who was invited by Kim last month at a high-profile summit in Russia's far east.

Earlier in the day, Lavrov lashed out at what he termed a "dangerous" US policy towards North Korea while touting the "new, strategic level" of relations between Moscow and Pyongyang.

"Like our North Korean friends, we are seriously worried about the intensification of military activity of the United States, Japan and South Korea in the region and by Washington's policies," Lavrov told journalists, according to Russian news agencies.

"We oppose this unconstructive and dangerous line," he said, adding that the United States was placing "strategic infrastructure, including nuclear elements", in the region, without elaborating.

In the face of a record-breaking series of weapons tests by Pyongyang this year, Seoul has moved to strengthen its security relationship with traditional ally the United States while entering a trilateral defence arrangement that also includes Japan.

Seoul and Washington have staged joint military exercises with advanced stealth jets and US strategic assets, while an American nuclear-armed submarine in July made a South Korean port call for the first time in decades.

A B-52 bomber capable of carrying a nuclear payload currently sits at Cheongju airport, about 100 kilometres (62 miles) south of Seoul, marking the first time one has landed in the country since at least 2000.

Local media reports said this week that the bomber would take part in a joint aerial drill near the Korean peninsula on Sunday that would involve South Korea, the United States and Japan.

Tightening relationship

But North Korea's relationship with Russia has also been tightening, Lavrov said Thursday.

"After the landmark summit... we can say confidently that relations have reached a qualitatively new, strategic level," Lavrov reportedly told North Korean Foreign Minister Choe Son Hui at a meeting.

Moscow is also keen to assist North Korea with its energy needs, a constant source of struggle for heavily sanctioned Pyongyang, he told Russian outlets.

"There is geological exploration, there are also plans for the supply of energy resources and other goods that our friends from the DPRK need," Lavrov said, using the acronym for North Korea's official name.

Both energy issues would be discussed at a joint meeting slated for November, he added.

Lavrov, who laid wreaths at monuments to former North Korean leaders Kim Il Sung and Kim Jong Il in the morning, arrived in Pyongyang on Wednesday night after accompanying Putin on a trip to Beijing.

At a welcome dinner, he praised Pyongyang's support for Russia's ongoing war in Ukraine.

"We highly value your principled, unambiguous support for Russia's actions in connection with the special military operation in Ukraine," Lavrov was quoted as saying by Russia's RIA Novosti news agency.

Weapons transfers

Kim travelled to Russia last month aboard a specially built bullet-proof train for a face-to-face meeting with Putin, declaring bilateral ties with Moscow his country's "number one priority".

The two leaders met at Russia's Vostochny Cosmodrome, roughly 8,000 kilometres from Moscow, a location seen as symbolic given North Korea's space aspirations.

The September summit fanned Western fears Pyongyang might provide Moscow with weapons for its war in Ukraine.

On Friday, the United States said arms shipments were already underway, with North Korea delivering more than 1,000 containers of military equipment and munitions to Russia in recent weeks.

According to a graphic provided by the White House, a load of containers was shipped by sea from North Korea to Russia between September 1 and October 1.

They were then delivered by rail to an ammunition depot about 290 kilometres from the Ukrainian border.

Pyongyang was seeking a range of military assistance in return, including advanced technologies, White House national security spokesman John Kirby told reporters.

Moscow this week denounced the allegations, insisting Washington had no proof that weapons were being shipped.

Washington-based analysts Beyond Parallel last week separately released satellite images showing what they termed an "unprecedented" build-up of train traffic along Russia's border with North Korea.

The flurry of activity "likely indicates North Korea's supply of arms and munitions to Russia", the group said in its report.
