PARIS — Interpol has made a formal request to China for information about its president, a Chinese citizen who seemingly vanished on a trip home, citing concerns for his well-being.

The agency for global police cooperation used law enforcement channels to submit its request about the status of its missing president, Meng Hongwei, it said Saturday in a brief statement.

The agency “looks forward to an official response from China’s authorities to address concerns over the president’s well-being,” the statement added.

Officials in China, which is in the middle of a weeklong national holiday, had yet to comment.

Mr. Meng’s wife says she has not heard from him since he left Lyon, the city in central France where Interpol has its headquarters, in September. France has begun its own investigation, with the French authorities saying that he had boarded a plane and arrived in China, but that his subsequent whereabouts is unknown.
