The draw was held at the Main Press Centre in the Olympic Park earlier yesterday.
In the women's singles draw, world champion and number one seed Wang Yihan of China will face the unseeded Michelle Li of Canada in her opening match of the Games.
In the mixed doubles, top seeds Zhang Nan and Zhao Yunlei of China will face Great Britain's medal hopefuls Chris Adcock and Imogen Bankier in the group stage of the tournament.
Adcock and Bankier were runners-up to Zhang and Zhao at the 2011 world championships at Wembley Arena, but the British pair have since beaten their Chinese opponents twice in three meetings.
In the women's doubles, China will be seeking their fifth consecutive Olympic title from their top pairing, world champions and number one seeds Wang Xiaoli and Yu Yang.
The badminton tournament begins at Wembley Arena on 28 July.
