According to the data by South Korea's Consulate General in Vladivostok, the trade between the North and Russia's Far Eastern region totaled $10.69 million during the Jan.-March period, up from $3.72 million tallied a year earlier.
Russia's exports to the North came to $10.67 million, while the North's exports to the Russian border region amounted to $20,000, the data showed.
Oil-related products, including refinery fuel, accounted for the largest portion of the Far Eastern region's exports to the North, with $9.08 million worth of such goods shipped across the border.
The spike in border trade came as Pyongyang is apparently pushing to consolidate its ties with its neighboring countries, including Russia, to ease the impact of crushing global sanctions.
North Korean leader Kim Jong-un traveled to the Russian border town of Vladivostok in late April for his first-ever summit with Russian President Vladimir Putin. They agreed to boost bilateral cooperation in various areas. (Yonhap)
