Russia and North Korea are “actively advancing” their negotiations over a potential arms deal that would provide significant ammunition for different types of weapons systems, including artillery, in the latest indication that the Kremlin is desperate to obtain further materiel for its faltering invasion of Ukraine, according to newly released US intelligence.

The news of the potential deal comes despite North Korea’s public claims to the contrary.

The Biden administration said Wednesday that they remain concerned that the two pariah states are in the middle of arms negotiations and that, following Russian Defense Minister Sergei Shoigu’s trip to North Korea last month, a second delegation of Russian officials have visited Pyongyang for further discussions on a potential deal.
