South Korea will present some of its intelligence to NATO officials at a North Atlantic Council meeting on Monday, Bloomberg reports. Seoul has also handed over these documents to the allies.
According to intelligence reports, the second batch of North Korean troops will soon head to Russia.
The first group of 1,500 special forces soldiers is already undergoing training in the Russian Far East as part of a planned deployment of about 10,000 soldiers.
South Korea has also collected information on the volume of military assistance provided by the DPRK to Russia. Thus, since August last year, Pyongyang has sent Moscow about 8 million North Korean-made 122 mm and 152 mm shells. About 100 Hwasong-11 missiles, as well as Bulsae-4 anti-tank weapons, were also discovered for the first time on the battlefield in Ukraine.
The figures are significantly higher than some European estimates of North Korean arms shipments to Russia.
