The speaker of the Russian Duma has asked a parliamentary committee to study a proposal to condemn the reunification of Germany in 1990.

Sergei Naryshkin earlier this week faced scathing criticism of Russia's annexation of Crimean peninsula when he spoke at the Parliament Assembly of Europe.

Russian news agencies say Communist deputy Nikolai Ivanov on Wednesday proposed a resolution to condemn what he called the "annexation" of East Germany in 1990. Ivanov said that unlike in Crimea, there was no popular vote to support the German reunification.

Negotiations between East and West Germany, and among foreign powers including the Soviet Union, resulted in a unification treaty officially granting full sovereignty to Germany on Oct. 3, 1990.

Naryshkin recommended that a committee consider Ivanonv's proposal before putting it to vote.
