USADA officials had told Armstrong he must speak with them if he wanted to reduce his lifetime ban from sports, and Thursday was the deadline for him to agree to the interview under that offer, Stuff.co.nz reports.
After more than two months of negotiations, Armstrong's lawyer Tim Herman said the disgraced cyclist wouldn't participate in a process designed only to demonise selected individuals.
Armstrong said previously he was willing to participate in an international effort to clean up a sport that was based mostly in Europe, the paper said.
For years, Armstrong denied using performance-enhancing drugs, but last year, USADA released a report that detailed extensive doping on his seven Tour de France-winning teams and stripped him of those titles, and Armstrong admitted last month that he doped to win those races.
Herman said they remain hopeful that an international effort will be mounted and they will do everything they can to facilitate that result.
Herman added Armstrong would not participate in USADA's efforts to selectively conduct American prosecutions that only demonise selected individuals while failing to address the 95 per cent of the sport over which USADA has no jurisdiction.
Armstrong is facing several legal challenges, and testifying under oath to USADA could have exposed him to further troubles. (ANI )
