The midfielder, who has lost his spot in the South Korean side since the scandal broke, was released and returned home in March after nearly 10 months of detention in China.
Son said he had agreed not to talk about his experience during detention as a condition of his release but decided to speak up because he was shocked to be included in China’s bans.
He was not mistreated during detention, Son added, but described the conditions in which he was held as harsh.
The Chinese Football Association could not immediately be reached for comment on Son’s remarks. The General Administration of Sport of China and the foreign and public security ministries did not immediately respond to requests for comment.
Three former Chinese internationals, Jin Jingdao, Guo Tianyu and Gu Chao were also banned for life, in findings made public on Tuesday at a press conference by the public security ministry and the General Administration of Sport of China.
When he was detained in China last May, its foreign ministry said Son, who was playing for the Chinese Super League club Shandong Taishan FC, was suspected of accepting bribes.
Son, who has now signed for South Korean side Suwon FC, said he hoped to continue his career.
