This comes just two days after the United States Wednesday announced fresh sanctions on Moscow, including various economic penalties on President Vladimir Putin's adult daughters as well as his top officials.
According to details in the US sanctions package, Putin's daughter Katerina Vladimirovna Tikhonova is a tech executive whose work supports the Russian government and its defence industry.
On the other hand, his elder daughter Maria Vladimirovna Vorontsova leads government-funded programs that have received billions of dollars from the Kremlin for genetics research, and are personally overseen by Putin, the United States said.
About the EU sanctions, Maria Vorontsova and Katerina Tikhonova's names are there in the EU's updated list of individuals facing assets freeze and travel bans.
While a little deal is known about Putin's daughter, in 2015, the Russian President disclosed a few details about his daughters, including that both women graduated from Russian universities and speak multiple languages.
The topic of Putin`s wealth is a sensitive subject in Russia. The Kremlin last year denied that he was the owner of an opulent palace on the Black Sea, as alleged by opposition politician Alexei Navalny in a video that drew a huge audience on YouTube.
