Abramovich, the owner of Chelsea soccer club who has found himself without a visa to Britain, took Israeli citizenship on Monday and will move to Tel Aviv where he has bought a property, the Israeli news website Ynet said.
Abramovich, 51 has traditionally enjoyed good relations with the Kremlin and served as a regional governor in a remote Russian region from 2000-2008.
"The Kremlin doesn't think anything about this," Kremlin spokesman Dmitry Peskov told reporters when asked about Abramovich's Israeli move.
"An entrepreneur has received Israeli citizenship. So what? It is his right," said Peskov.
