Mr Türk said the already alarming situation in Haiti had deteriorated in recent week as gangs launched attacks.
France is opening special flights to evacuate its “most vulnerable citizens” from Haiti amid armed unrest in the country, the French foreign ministry said.
Mr Henry said the government he leads will withdraw immediately after the inauguration of the council.
While Haiti has been in crisis for some time, it has been reeling since the July 7, 2021, assassination of President Jovenel Moise.
More than half of the funds, just over a billion dollars, will be needed to rehabilitate or rebuild mainly private housing, and around $400 million is earmarked for education.
Haiti’s national police on Sunday announced the arrest of the suspected mastermind in the assassination of President Jovenel Moise.
