The government is considering formulating legislation to discourage doping in sports in preparation for the 2020 Tokyo Olympics and Paralympics, sources close to the matter said Saturday.

The government is seeking to project a strong antidoping stance both domestically and internationally in the runup to the games, particularly following the International Association of Athletics Federations' suspension of Russia from international competition last month, the sources said.

The suspension by athletics' world governing body amid allegations of a systematic, state-sponsored Russian doping program has prompted scrutiny over the threat of doping in other sports.
