Once a North Korean experiment in limited capitalism, the Rason Special Economic Zone appears to be the epicenter of the isolated country's growing cooperation with Russia, experts say, including possible shipments of arms for the war in Ukraine.
With apartment blocks and booming markets flooded with imported goods, the Rason SEZ, established in the 1990s on the border with China and Russia, was a dream destination for many North Koreans before tighter sanctions hit and pandemic-era border closings choked off nearly all trade and tourism, two experts who study Rason said.
In recent months, there have been clear signs that the area is poised for a comeback, with ships docking there for the first time since 2018, and satellite imagery suggesting a spike in trade from both the port and a rail line to Russia.
Although China, with its vastly larger economy and deeper historic ties with North Korea, might seem the obvious driver of a recovery in Rason, experts say the country's deepening cooperation with Russia may make a more immediate impact.
"Now that North Korea and Russia are becoming very close against the backdrop of the Ukraine war, Russia might send more tourists to North Korea, which can reinvigorate tourism (in Rason)," said Jeong Eunlee, a North Korea economy expert at South Korea’s government-run Korea Institute for National Unification.
Russia can also sell coal, oil, and flour through Rason, Jeong said, and if more North Korean workers are allowed to cross the border, they can send Russian medicine and other goods home for relatives to sell.
The Russian Federal Customs Service said it had "temporarily suspended the publication of foreign trade statistics."
China accounted for 97% of North Korea's overall trade in 2022, according to South Korea's Korea Trade Investment Promotion Agency.
But Russia resumed oil exports to North Korea in December 2022 and had exported 67,300 barrels of refined petroleum to North Korea by April, United Nations data shows, the first such shipments reported since 2020.
Lee Chan-woo, a North Korea economy expert at Teikyo University in Tokyo, said Russian wood cut by North Korean loggers could be resold to China through Rason, a city of about 200,000 people.
Cho Sung-chan of Hananuri, a South Korean nonprofit that has financed a food-processing factory in Rason, predicted Russian influence there would grow.
"Assuming North Korea and Russia's honeymoon period becomes a long one, North Korea could get Russian support on food, energy and infrastructure through Rason," Cho said.
The two countries discussed expanding trade and testing delivery of meat products next year, Russia's natural resources minister Alexander Kozlov said on his Telegram channel after meeting with North Korean officials in Pyongyang in November.
Since August, Rason's port has seen visits from Russian ships linked to that country’s military logistics system, according to U.S. and South Korean officials and reports by Western researchers citing satellite imagery.
Those ships are suspected of carrying military supplies from North Korea to Russia, the reports said. The Kremlin has denied such shipments.
From Rason's port, North Korea has sent Russia an estimated 2,000 containers suspected of carrying artillery shells, and possibly short-range missiles, South Korean military officials have told reporters.
Since late 2022, activity has been spotted around Rason's Tumangang station, which has rail links to Russia, said Chung Songhak, a senior researcher at the Korea Institute for Security Strategy who analyzes satellite imagery around Rason.
More train carriages were spotted after the Russian defense minister visited Pyongyang in July, Chung said, citing satellite imagery, adding that possible new cargo depots popped up in May.
When leader Kim Jong Un visited Russia in September, he discussed restarting a stalled joint logistics project in Rason, building a new road bridge connecting it with Russia and additional grain supplies, Kozlov said.
Since Kim’s grandfather, Kim Il Sung, designated Rason a special zone in 1991 after the Soviet Union’s collapse and as China opened further, North Korean officials have tried to attract investment there.
Rason, the oldest and largest of North Korea's 29 economic development zones, has been central to the country's push to attract foreign investment.
It has one of North Korea's first and biggest markets, was the site of the country's first mobile network, and is the only place where North Korea legalized buying and selling homes in 2018, according to experts and North Korea’s government publications.
The other zones have had poor results because of shaky infrastructure and international sanctions, according to South Korea's National Institute for Unification Education.
Lee of Teikyo University said that whichever outside country helped reinvigorate the special economic zone, it offered a potential bright spot for North Koreans after years of pandemic restrictions.
"Rason took a harder hit than other places in North Korea because it used to be on the front lines of the opening," Lee said. "Now many businesses have collapsed there, but as soon as the border fully reopens, North Koreans might think that the paradise can come back."
