Seoul, Kim's plants at full capacity to give weapons to Moscow. The North is estimated to have shipped about 6,700 containers to Russia since the September summit between leader Kim Jong-un and President Vladimir Putin.

They are sufficient volumes to transport approximately 3 million 152 mm artillery shells or 500,000 122 mm shells. The weapons factories "generally operate at 30 percent capacity due to shortages of raw materials and energy," Yonhap reports. Reproduction reserved © Copyright ANSA 2014.
