Venezuela has become the latest country to face a loss of Olympic quota places in terms of weightlifting due to multiple doping offences.

As all current doping cases are dealt with, many of which are still being processed by the International Testing Agency (ITA), there are at least 20 countries that could be either banned outright or unable to send full weightlifting teams to Tokyo 2020 Summer Olympic Games due to doping offences.

Jeyson Mosquera, having won three competitions on 102 kilograms level last year, has been suspended provisionally after testing positive for hormone and metabolic modulators. There are a total of nine Venezuelan weightlifters who were suspended for doping between 2009 and 2017.

If the case of Mosquera is closed, it will take Venezuela to 10 cases and as a result, a restricted quota of 2 men and 2 women will apply.

Countries that have fewer than 10 positives since the Beijing Olympic Games in 2008 can send a maximum team of eight weightlifters, equally including four men and four women, to Tokyo next year.

Those countries with 10 to 19 violations only have half that number and those with 20 or more could send only one male and one female athlete.

The International Weightlifting Federation (IWF) has updated the list of nations with restricted quotas earlier this month, which is under close scrutiny by the International Olympic Committee (IOC) due to its doping record.

The IOC issued a statement on Wednesday noting that Vietnam was liable to be banned outright from 2020 Summer Olympics after two additional doping suspensions were publicized on the website of the IWF last week.

That took to four Vietnamese lifters banned for doping since Olympic qualifying started in 2018.

Any country with at least three doping cases in the Tokyo 2020 Olympics qualifying period, which ends in April, 2021, faces an outright ban.
