Yili has been the only dairy product sponsor for the Olympics in China since 2005, including Beijing 2008 when they were also the sponsor of diary products. 

Pan Gang, chairman and President of the Inner Mongolia Yili Industrial Group, said that the Olympic spirit of "higher, faster, stronger" has already been integrated into Yili's genes. 

Chen Jining, the Acting Mayor of Beijing and Executive President of Beijing 2022, attended the signing ceremony at the National Aquatics Centre in the Chinese capital.

Zhang Jiandong, Deputy Mayor of Beijing and vice-executive president of Beijing 2022, and Pan signed the partnership agreement.

"Yili has a history partnering the Olympic Games and Paralympics," said Pan.

"We will do our best to provide Beijing 2022 and all Olympic Family members with first-class dairy products.

"We will commit to promote the development of winter sports and advocate a healthy lifestyle for all."

Yili is claimed to be the number one dairy group in Asia, and is the only Asian dairy group that has been listed in the top eight global dairy groups. 

"We congratulate Yili in becoming the official dairy products partner for Beijing 2022, following its partnership with Beijing 2008," said Zhang.

"We believe Yili will provide quality products and services as an official partner of Beijing 2022."

Beijing 2022 launched its marketing programme in February this year.
