The company's press service said the purchase of shares of one of the largest banks in the Far East was in line with AFK Sistema's strategy for the development of its banking group.
The banking group incorporates the Moscow Bank for Reconstruction and Development, among top 30 Russian banks, and Luxembourg-based East-West United Bank.
"Dalcombank will harmonically add to the group's network, which has not yet expanded to the Far East," the company said in a news release.
Dalcombank is known for mediating the transfer of North Korea's frozen funds from Macao in June as part of a deal on the North's denuclearization.
AFK Sistema President Alexander Goncharuk earlier said his corporation planned to complete the acquisition of regional retail banks by 2008, and that the banking group could make its way into Russia's 15 largest banks. He also did not rule out that a strategic investor could be admitted to the group.
AFK Sistema manages businesses in service-based industries, including telecommunications, technology, insurance, banking, real estate, retail and media.
