The town of Leninogorsk (Kazakhstan's north-east) will regain its historic name - Ridder, the press service of the Eastern-Kazakhstan regional administration said on Tuesday.
The new name of the town will be approved at a meeting of the municipal parliament on June 13.
The decision to rename the town was taken by the special onomastic commission.
The town of Leninogorsk had the name Ridder from 1786 till 1941. It was called so after Philip Ridder, who discovered the local deposit of poly-metallic ores.
The choice of the city of Helsinki is not incidental as the capital of Finland had hosted US-Soviet negotiations on the limitation of nuclear stockpiles in 1969
