BEIJING — A former senior Chinese police official who also served as president of Interpol was sentenced on Tuesday to 13 and a half years in prison for bribery, in a case that his wife has denounced as stemming from a political vendetta.

When the official, Meng Hongwei, was elected president of Interpol, the French-based international body that provides global coordination in fighting crime, in 2016, the appointment raised fears among rights groups that China would use the connection to abuse the organization’s powers.

But two years later, Mr. Meng disappeared abruptly on a return visit to China, whose ruling Communist Party later disclosed that he was under investigation.

On Tuesday, a court in Tianjin, a port city in northern China, found that Mr. Meng had taken bribes worth more than $2 million from 2005 to 2017, when he was rising in China’s domestic security apparatus. The judgment, and the lengthy prison sentence, followed a one-day trial in June last year.
