Kenya has offered to take the lead in a UN security mission aimed at stabilising Haiti after the US secretary of state, Antony Blinken, appealed for more international support.
He told a meeting in New York that there was no time to lose.
Mr Blinken promised another $65m (£53m) to help the police in Haiti.
He again urged the Security Council to sanction the deployment of a UN-backed mission.
Haiti has suffered worsening security problems since the killing of president Jovenal Moise two years ago.
Gangs control much of the capital, Port-au-Prince and there were more than 2,000 killings in the first half of the year while 1,000 people were kidnapped.
