Banka said he was “very interested” in working alongside the United States Anti-Doping Agency (Usada), but “it has to be based on mutual respect” as tensions between both organizations have been high in recent times.
Earlier this year, USAda said it “fully supported” the US government’s decision to withhold a $3.6m (£2.8m) payment to the World Anti-Doping Agency (WADA).
This came during a dispute over the handling of a doping scandal involving Chinese swimmers who were cleared to compete at the Tokyo Olympics in 2021, despite testing positive for a banned substance months earlier.
An independent investigation found that Wada did not mishandle the case or show bias toward the 23 swimmers.
On Thursday, Banka added: “We really want our US colleagues to do more to ensure this event does not happen.
“There are some legal possibilities they can push for. USAda has made general comments, but maybe it’s time to try to convince the people who have funded this that it’s dangerous.
“That’s all [Usada’s] role and responsibility because the event is going to take place in Las Vegas.
