"The other (brands) will find other parts to play and get PR coverage like sponsoring the national teams. They should still be able to get exposure at the Games," said a source.
In the 2004 Olympics, both Li-Ning and Nike sponsored national teams. The sponsorships saw the two brands face off on the basketball court, with Li-Ning backing the Spanish team and Nike sponsoring China's national team.
Adidas will supply sportswear for all staff, volunteers and technical officials of the Games and the Paralympic Games. It will also outfit the Chinese Olympic teams.
Six other companies are reported to have signed up with the Beijing organisers, including Volkswagen, Bank of China and China Mobile.
