Police sources said Meng's wife and children remained in Lyon.
The French official said Meng did arrive in China.
By 2004, he was a vice minister of public security and that same year became head of Interpol's China branch.
The Interpol president has not been in touch since September 29.
Rights groups have previously expressed concern Beijing might try to use Mr Meng's position at the body to go after dissidents overseas.
Trump says he and Kim Jong Un 'in love'
Mr Trump grumbled that commentators would cast him as "unpresidential" for describing Mr Kim in such glowing terms. He said the U.S. was insisting on a "denuclearisation first" policy that "increased the level of sanctions".
Interpol says it's aware of reports that President Meng Hongwei has been reported missing while making a trip to his native China.
Beijing has tried for many years to enlist the help of foreign countries to arrest and deport back to China citizens it accuses of crimes including corruption and terrorism.
A person familiar with the investigation into the disappearance said the initial working assumption of Western investigators was that Meng had antagonized Chinese authorities in some way and had been detained as a result.
The director of Interpol has gone missing after traveling to China last week, multiple outlets report.
He was the first Chinese official to become Interpol president, Chinese state news agency Xinhua said at the time.
A report from Le Parisien translated by NPR said Meng's wife became anxious when he fell out of touch after arriving in China. It also pointed out that the day-to-day running of the 192-member global organisation for police co-operation was handled by its secretary general, not the president. Mr Xi has waged a campaign against corruption and has sought the return of suspected officials and businesspeople who fled overseas.
