The European Union is set to launch a first operation in a new propaganda war with Russia within days of EU leaders giving formal approval to the campaign at a summit Thursday.

Officials said that a dozen public relations and communications experts will start work by the end of March in Brussels with a brief to counter what the EU says is deliberate misinformation coordinated by the Kremlin over Moscow's role and aims in Ukraine and elsewhere in Europe.

It is the first stage of a plan that leaders want EU foreign policy chief Federica Mogherini to finalize by June, which may include efforts to produce and share Russian-language broadcast programming, notably for ethnic Russians in former Soviet states.

Those communities currently tune in heavily to Russian state broadcasters, which have bigger production budgets than local stations for their entertainment output, as well as news.

EU leaders, especially in the Baltic states, have been alarmed at how Moscow has used its media to gain support for its views and policies — with budgets that are still likely to dwarf the few million euros a year that officials said the EU may provide.

EU leaders agreed Thursday to extend economic sanctions to push Russia to respect a Ukraine peace deal. And a summit statement also said they "stressed the need to challenge Russia's ongoing disinformation campaigns," tasking Mogherini to deliver fully fledged plan by June.

The new Brussels unit's immediate task is the "correction and fact-checking of misinformation" and to "develop an EU narrative through key messages, articles, Op-Eds, fact sheets, infographics, including material in Russian language," according to a description circulating among EU officials.

The EU already provides some support for media within the bloc and beyond, including grants and technical assistance to support diverse cultural programming and coverage of EU affairs. It could now look at linking some of that aid to countering Russian influence.

The EU-funded European Endowment for Democracy, which promotes democratic development in neighboring regions, will present proposals on media issues to a summit in Latvia on May 21-22, where EU leaders will meet those from Ukraine and a handful of Russia's other ex-Soviet neighbors.

EED Director Jerzy Pomianowski said one option being studied is "greater integration and cooperation" among existing Russian-language media in states bordering Russia, to share content that can compete for audiences with Moscow-funded programming.

One EU official said experts could be brought in to help produce programs to attract Russian speakers who do not tune in to existing Western-funded Russian-language media such as the BBC, RFI, Deutsche Welle or Radio Free Europe. "We need to spread the word beyond the usual suspects," he said.

Still, EU officials involved in the project said they cannot hope to compete head-on with the expensive news and entertainment channels that Russia beams far beyond its borders, or the teams that promote Kremlin ideas on social media.

The bloc is also constrained by a reluctance to be seen as manipulating news content or to be engaging in overt "propaganda."

"Countering Russia's hard propaganda with its same weapons would not be effective and is not feasible," another EU official said.
