Belarusian authorities have released an imprisoned U.S. citizen, a Belarusian journalist for a U.S.-funded media outlet and an opposition supporter in an apparent attempt to repair ruptured ties with Washington.

Aleksandr G. Lukashenko, Belarus’s autocratic president and Russia’s closest ally, has taken steps to soften his country’s isolation from the West.

Andrey Kuznechyk, a journalist with Radio Free Europe/Radio Liberty, was one of those released from a Belarusian prison after more than three years. The released American has not been named publicly.
