"Instead of widening these sanctions, as the government has done, it should eliminate them," Denber said.
She stressed that the Ukrainian government's decision to impose sanctions on Russian media outlets had taken a toll on democracy in Ukraine.
"The Ukrainian government’s sanctioning of Russian state media outlets falls is part of a series of measures it has taken that limit media pluralism and freedom of expression and undermine democracy in Ukraine," Denber said.
Dender added that Kiev may have reason to strongly disagree with Russian state media coverage.
"But instead of blocking these outlets it should ensure that the public has adequate information to challenge them. This should be a key issue that Ukraine’s international partners discuss with the government," she said.
On Thursday, Ukraine included the Russian news agency Sputnik on its sanctions list for three years and blocked the news agency’s assets and websites.
