Russian athletes and sports officials voiced disbelief on Monday that one of their Winter Games medallists was being investigated for suspected doping, a scandal that could imperil Russia's efforts to regain full Olympic status.
South Korean President Moon Jae-in has lauded Russia's participation at the Winter Games, saying it has "made our Olympics better". "It raises a lot of questions", Svishchev said.
"There's no place for it in the Olympics for cheating and doping".
"The test taken from Alexander Krushelnitsky before the start of the Olympic Games, on January 22 - as well as all the previous ones - was negative".
Krushelnitsky was one of 168 athletes passed as "clean" and allowed to compete as neutrals after a targeted testing programme stretching back over several months.
Former tennis world number one Maria Sharapova of Russian Federation was barred from competition for 15 months after testing positive.
Meldonium's main use is to treat ischaemia, which is a lack of blood flow to parts of the body, particularly in cases of heart failure or angina.

There are reports that Krushelnitckii has turned in his accreditation and left the site of the Winter Games; Adams said on Monday that he had heard those reports but had not received confirmation. "There's a possibility of it being something within the team, that something happened during training camp, or as a political means to achieve some goal". "Of course we very much hope it was some kind of mistake", Russian curler Viktoria Moiseeva said, adding the team believed Krushelnitsky was innocent.
Fitness is even more important in mixed doubles, the event at which Krushelnitsky was competing.
"To have that quick recovery and to be able to sweep again and again and again, it could definitely benefit you", Canadian curler Marc Kennedy told the Washington Post. My sweepers are working out like five times a week, go to the gym, so it (performance-enhancing drugs) can help, but we shouldn't do that.
"First of all, I want to apologise to my partners on the Olympic team, our delegation and all the fans for not being able to protect ourselves and Nastya from the problems that we faced today", Krushelnitckii said in a statement, sent to insidethegames. The IOC is expected to make a decision this Saturday.
"I feel mostly bad for Russian Federation because they got banned from this one and if some of their athletes are still getting caught positive, it's sad for them because who knows what the ramifications are going to be".
"I've played in the same mixed doubles tournaments as that team and they're good people".
