The 43-year-old Nedved, like Beckham a former winger, enjoyed a trophy-laden career with Sparta Prague, Lazio and Juventus as well as winning 91 caps for the Czech Republic and the Ballon d'Or in 2003.
"Before me it was David Beckham so it's a great honour for me and for the entire Czech Republic," Nedved was quoted as saying by Xinhua state agency on the sidelines of Xi's visit to Prague on Wednesday.
The Chinese Super League dubbed Nedved, currently vice-president at Italian champions Juventus, "Czech Ironman" and said he had all the characteristics required to be a good ambassador for the league.
"Nedved is known for his outstanding football skills and more importantly his never-say-die spirit. His fighting spirit fits well in what the Chinese Super League calls for," it said in a statement.
