"There is no list, but many have already announced their wishes [to visit Crimea]… Germany, Italy," Kovalyov, who is representing Russia at the Organization for Security and Co-operation in Europe Parliamentary Assembly (OSCE PA) in Mongolia’s Ulaanbaatar, said.
He added that the talks being held with groups from these countries were not official.
According to Kovalyov, the surge in interest could be attributed to a similar visit by French parliamentarians to the peninsula earlier this year.
On Tuesday, Hungarian Jobbik party told Sputnik it was contemplating a visit to Crimea.
Crimea joined Russia in March 2014, after more than 96 percent of Crimea voters backed the move in a referendum.
The West and Kiev did not recognize the legitimacy of the vote, imposing sanctions on Russia over what it calls the Crimean "annexation." Moscow has pointed out that the referendum was held in accordance with international law.
