The International Olympic Committee is preparing to announce sanctions against Russia during its executive board meetings, which begin on Dec. 5, little more than 60 days before the Games begin. Among the penalties officials are considering are barring the country’s national anthem from playing at the Games and keeping its delegation of athletes out of the opening ceremony.

Thomas Bach, president of the International Olympic Committee, said in an interview with The New York Times on Tuesday that he was unaware the Paralympic Committee was requiring Russia to be cleared by antidoping regulators, and he suggested he saw no problem with allowing the nation to compete even as it is deemed uncooperative by the global watchdog.

“I think everybody would like to see RUSADA working at full speed so that the Russian athletes can be tested,” Mr. Bach said, using the acronym for Russia’s antidoping agency. “The past has to be sanctioned. The question now is about the future, and these are two different things.”

Margarita Pakhnotskaya, a deputy director general for Russia’s antidoping agency, said in an email Wednesday that the “RUSADA team is working hard in all functional areas of the agency,” adding that the staff “now are working with the corrective actions.”

Russia’s antidoping agency has been considered noncompliant since 2015, when global authorities first accused the country of coordinated cheating. In the wake of a tell-all account from the former head of Russia’s national antidoping lab, Dr. Grigory Rodchenkov, the scope of the scandal broadened drastically, causing more than 100 Russian athletes to be barred from competing at the 2016 Summer Olympics. The antidoping regulator itself called for Olympics officials to exclude the entire nation from those Games.

“We really have done everything possible for RUSADA to retrieve its status,” Mr. Kolobkov, the sports minister, told the R-Sport news agency in recent days, striking the same defiant tone he did in Seoul, where he was accompanied by Alexander Zhukov, the head of the Russian Olympic Committee.

Among the requirements that antidoping authorities have made of Russia is that the nation provide access to urine samples stored in its national lab in Moscow. Russia has refused, citing its own criminal investigation relating to those samples.
