"Ambassador Sullivan: 'Arrived back in Moscow today. Ready to work with the @USEmbRu team toward progress on U.S. foreign policy priorities, and with #Russia on our goal of a stable and predictable relationship between our countries,'" Jason Rebholz, spokesman for the US Embassy in Moscow, tweeted.
Sullivan and Russian Ambassador to the US Anatoly Antonov travelled to their home countries for consultations this spring amid the deterioration of bilateral relations. Antonov returned to the US on Sunday.
