IOC to buy vaccines from China for Tokyo, Beijing Olympic competitors
"The IOC will also pay for two doses more that can be made available to people in that country," in what Bach said was a "demonstration of solidarity" in the fight against the Covid-19 pandemic.
"This can be via international partners or in countries where partnerships are already in place with the Chinese government," he said.
Bach added that a significant number of Olympic teams "have already been vaccinated".
"Another significant number have received a commitment from their governments or are in very positive discussions."
Bach also tried to play down risks to Japan from hosting the Olympics, citing the fact that 270 world championships had been held involving more than 30,000 athletes following "rigorous health and safety protocols" since September 2020.
"Not a single one of these events turned into a virus spreader," Bach said, adding they had posed no danger to host communities: "It's clean and obvious proof."
The Tokyo Games were originally scheduled for the summer of 2020, but it was pushed back by one year as the coronavirus pandemic raged across the globe.
They are now scheduled for July 23-August 8, Bach at pains to reiterate that the IOC remains committed to holding a "successful and safe" Games this year, dismissing cancellation talk as "speculation".
Overseas spectators, however, are likely to be shut out, as Japanese organisers prioritise public health and safety.
