The director helmed the hugely successful "Mission: Impossible - Rogue Nation", which released earlier this year, said the Hollywood reporter.
He confirmed recently that he is involved in the development of the upcoming latest instalment in the franchise.
With a vague tweet, Christopher wrote, "Mission: Accepted #MI6."
However, Christopher did not reveal in which capacity he would be returning - as director or scriptwriter, or both.
The next film, temporarily titled "Mission: Impossible 6", will be the third time franchise star Tom Cruise has joined forces with Christopher.
As well as "Rogue Nation", Christopher also wrote and directed 2012 film "Jack Reacher".
