Russian President Vladimir Putin has ordered all Russian companies to ready themselves for a rapid transition to ‘war-time operations.’

Both state-owned and private corporations must be prepared for a potential conflict with the West, Putin warned senior defense officials on Wednesday. reports: “I would like to note that the ability of any economy to rapidly increase the output of defense products and services when it is needed is one of the most important conditions of the nation’s military security. All strategic and… large enterprises must be ready for this,” Putin stated.

The Russian leader added that he and senior defense officials already discussed the issue in 2015 and 2016, and asked those attending the meeting to report which problems of the previous years had been dealt with and which had not.

The conference concerned the results of the Zapad 2017 military exercises held by the Russian and Belarusian military forces in September.

Russia accepted Belarusian troops at three of its own military sites.
