Russia will always assist its citizens detained abroad, President Vladimir Putin said in Vladivostok on Thursday, following a major prisoner exchange with Western countries in August.

“We treat all Russian citizens the same when they need the assistance of the state. And we will continue to do so in the future,” he said.
