The Court of Arbitration for Sport (CAS) has overturned the Olympic doping bans on 28 Russian athletes.
This has far reaching consequences for the Olympics as the Russian athletes could now compete at this month's Pyeongchang Games in South Korea.
There will be 10 other Northern athletes at the Games, taking place between 9 and 25 February, in sports including cross-country skiing and figure skating.
CAS external linksaid that in the 28 cases, the IOC-imposed sanctions had been annulled due to insufficient evidence and their results at the Sochi Games had been reinstated.
However, according to the CAS statement, the court "unanimously found that the evidence put forward by the International Olympic Committee in relation to this matter did not have the same weight in each individual case".
"I hope that this page will be turned, and moreover, in the very near future", the Russian president told a gathering of his supporters in Moscow ahead of March's presidential election. However, CAS reduced their lifetime Olympic bans.
He said Russia considers the decisions not to allow some Russian athletes to take part in the 2018 Olympics to be odd.
President Moon Jae-in has seen his support rate drop over his administration's response to North Korea's participation in the Games, especially after it chose to form a combined women's ice hockey team with athletes from the two Koreas for the Winter Olympics. Appeals of 11 others are partially upheld.
"I call on all our athletes to follow all the rules that the International Olympic Committee suggests", Putin said, adding that Russian Federation would "financially support and morally support" athletes who weren't allowed to compete.
The long-time Russian leader said he hopes worldwide sports organizations "don't turn into departments of state agencies of certain countries".
Biathletes Olga Zaytseva, Olga Vilukhina and Yana Romanova will have their cases heard after the Pyeongchang Games. The ruling came in the wake of two independently-commissioned WADA reports which detailed state-sponsored doping schemes, including manipulation and swapping of urine samples, at the Sochi Games.
The British four-man team - led by pilot John Jackson - initially finished fifth, but could be upgraded to bronze after the International Olympic Committee disqualified the two Russian sleds - who finished first and fourth - following re-examination of the doping tests conducted at the time.
Jim Walden, lawyer for Dr Rodchenkol, issued a statement on Thursday that read: "Dr Rodchenkov testified fully and credibly at Cas".
