Putin says possible nationalization of Russian assets abroad is "a double-edged weapon"

Possible nationalization of Russian assets abroad is "a double-edged weapon", Russian President Vladimir Putin said on Tuesday, in comments suggesting that Russia was capable of responding in kind.

He was speaking a day after Germany said its energy regulator would take control of Gazprom Germania, a gas trading, storage and transmission business which Russia's Gazprom said it was exiting last Friday.

Putin also said that Russia needs to keep a close eye on agriculture exports to "unfriendly countries".
