This comes after a phone call between Israeli Prime Minister Benjamin Netanyahu and Russian President Vladimir Putin.
The Israeli Naama Yessakhar was detained in Russia, sentenced to seven years' imprisonment, and obtained presidential forgiveness on humanitarian grounds.
In return, Israel refused to extradite the Russian, Alexei Berkov, who was detained at Ben Gurion Airport in 2015.
On October 11, a Russian court sentenced Issaskhar, 25, to seven and a half years in prison for convicting drug trafficking.
The drugs were found in her bag while she was arriving to Moscow from India on her way to Israel in April 2019.
Netanyahu raised her file with Russian President Putin before and after the ruling.
He has promised her family to work for her release.
The call comes a week before Putin's visit to Israel on January 23, 2020, to participate in the commemoration of the 75th anniversary of the liberation of the Auschwitz Nazi camp in Poland.
