Russia warned South Korea not to be shocked if Moscow retaliated against Seoul for widening the list of commodities that cannot be exported from the East Asian country to Russia without special approval.

Seoul announced this week that it would add over 600 items to its export control list for Russia that could be used for military reasons.

The list includes heavy construction equipment, rechargeable batteries, aeronautical components, and some cars.

Russian Foreign Ministry spokeswoman Maria Zakharova told a news briefing on Wednesday:

“This is an unfriendly move taken at Washington’s behest. It will damage South Korea’s own economy and industry.

“We reserve the right to take measures in response, and not necessarily symmetrical ones. They (the South Koreans) should not be surprised (if and when we do).”
