The promoter of Formula 1's Russian Grand Prix is aiming to hold an ABB FIA Formula E race in St Petersburg in 2020.
Sergey Vorobyev, deputy general director of Sochi F1 promoter Rosgonki, explained that his organisation is in commercial talks with FE CEO Alejandro Agag.
"We are looking to host a Formula E race in St. Petersburg, starting with 2020," Vorobyev told Autosport.
"Considering that there'll be UEFA Euro games in St. Petersburg in 2020, and there's the traditional International Economic Forum in the same city, we are now looking, jointly with the organisers [of the other events], at potential possible dates and simultaneously discussing the commercial conditions.
"Our plan A is a race in St Petersburg, in spring or summer of 2020. And from then on hopefully every year.
"Currently we have four tracks developed, and whether one of them will be chosen or it'll be some combination, that will happen when Formula E makes an official technical visit to St Petersburg, which will be after the commercial aspects are agreed.
"But really we're close, and I'm very happy to be dealing with Alejandro Agag. It's reminiscent, in a way, of working with Bernie Ecclestone, whose departure was unfortunate.
"It's great to see a person with a real entrepreneurial spirit, a person who's single-handedly responsible for what happens in his racing series.
"Negotiating with him is not easy, but I'm certain that they're equally pleasurable for both sides and that they'll ultimately yield a result."
FE has raced in Russia before, with the Moscow E-Prix taking place in June 2015 during the championship's inaugural season.
When asked about the possibility bringing FE back to the Russian capital, Vorobyev said: "Moscow is not a priority.
"We're thankful to the organisers of the Moscow Formula E race in 2015, they truly paved a way for Formula E in Russia, but currently I believe St Petersburg is the ideal city to develop Formula E in Russia.
"And given there's Formula 1 interest in holding an F1 Live street festival during race week for the citizens of Moscow, I think we can have an ideal combination of events in 2020.
"[This would be] a Formula E race in St. Petersburg, the F1 Live show in Moscow and the Russian Grand Prix, the main event, in Sochi."
While FE does not comment on every city linked with hosting a new race, Autosport understands the series is keen to return to Russia.
Agag told Autosport last month that he "would really like" to work with Rosgonki on a potential St Petersburg race.
