The Paris Saint-Germain midfielder will help to promote the game within the Asian nation and worldwide after the country was rocked by revelations of a match-fixing scandal
As many as 33 officials and players were banned from football for life after being caught in the corruption, while another 25 have been suspended for five years.
Beckham, who recently signed for Ligue 1 side Paris Saint-Germain, will be part of attempts to promote the Chinese Super League (CSL) after the country's top flight recently lost stars such as Didier Drogba and Nicolas Anelka.
"I am honoured to have been asked to play such an important role at this special time in Chinese football history," Beckham said in a statement released by IMG.
"I'm excited by the prospect of promoting the world's greatest game to Chinese sports fans as I've seen first-hand the growing interest in football there.
"This is a wonderful sport that inspires people across the world and brings families together, so I'm relishing the opportunity of introducing more fans to the game."
As well as expanding the reach of the Super League worldwide, Beckham will work within China to help improve the standards and popularity of the sport internally.
"2013 marks the 20th anniversary of professional football in China and the special ambassadorship of David Beckham will attract global attention to Chinese football and the CSL," an unnamed Chinese Football Association official said in a statement.
"While in China, he will attend the CSL and visit clubs to get a deeper insight into football in China. He will also help us to inspire and motivate many children to participate in this beautiful game."
