Japan earlier this month was fined 200,000 yen (US$1,700) by a Japanese court Wednesday. Local office worker Xue Yi hurled the soft-drink bottles at Lee, 84, at Narita airport outside Tokyo but did not hit anyone.
Lee was ending a visit opposed by China which accuses him of attempting to seek independence for Taiwan, which it regards as part of its territory.
The court ordered 34-year-old Xue to pay the fine for the incident on an assault charge.
According to Japanese news agencies, prosecutors determined that Xue personally disliked Lee’s activities seeking Taiwan’s independence and that he did not have links to any organization.
During his visit, Lee made a pilgrimage to the controversial Yasukuni war shrine, which many Chinese and Koreans see as a symbol of Tokyo’s militarist past.
Lee said he paid the pilgrimage to mourn his late brother, who died fighting in the Japanese navy in 1945, when Taiwan was a Japanese colony.
China had demanded that Japan curb the activities of Lee, whom it reviles for promoting the island’s separate identity during his rule.
