Chelsea have issued an apology after admitting Instagram posts by Kenedy had caused "great offence and hurt the feelings of the people of China."
The defender posted the messages ahead of the Blues' 3-0 win over Arsenal at the Bird's Nest in Beijing on Saturday and the 21-year-old was jeered during the pre-season friendly.
He has since apologised for his comments and deleted the posts and said it was "not intentional" to cause any offence.
Yesterday afternoon, the Premier League champions published a statement on their official website also apologising.
"On July 22, Chelsea Football Club experienced the warmth and friendliness of Chinese fans at the National Stadium. However, we were surprised and disappointed that one day prior to the match, one of our young players, Kenedy, posted messages on his social media account that caused great offence and hurt the feelings of the people of China.
"Unfortunately, even though he quickly deleted the messages and apologised, and the club also apologised via our Chinese social media channels, the damage had already been done.
"Kenedy's actions were a mistake that he will learn greatly from. His behaviour does not represent the entire team and does not align with the club's high expectations. He has been strongly reprimanded and disciplined.
The statement concluded: "We offer this apology with utmost sincerity. We have listened carefully to the criticism and will use the lessons learnt to improve our processes in future".
Kenedy who Chelsea signed from Fluminense in 2015, made three appearances last season.
