STORY: Valieva, who turned 16 on Tuesday, failed a doping test at the Russian national championships last December but the result was only revealed on February 8, a day after she had already helped the Russian Olympic Committee (ROC) win the team event at the Beijing Games.
The case cast a shadow on Russians' participation at the Games as they already faced increased scrutiny over separate doping sanctions that saw them compete without their flag and national anthem.
"Through her work, she brought the sport to the level of a real form of art," Putin said Valieva at a televised awards ceremony at the Kremlin for medallists from the 2022 Beijing Winter Olympics.
"Such perfection cannot be achieved dishonestly with the help of additional substances, manipulations. We very well know that these additional substances are not needed in figure skating.
The International Olympic Committee (IOC) decided not to award any medals for the figure skating team event at the Olympics until Valieva's doping case has been resolved, something that could take months.
Several international sports federations, including the International Skating Union (ISU) governing figure skating, have barred both Russian and Belarusian athletes from taking part in international events over Moscow's invasion in Ukraine, which Russia calls a "special operation".
