Update from the UN:
The MSS mission is expected to comprise up to 2,500 police personnel, deployed in phases, at an annual cost of approximately $600 million. According to the latest available
information from the UN, eight countries—the Bahamas, Bangladesh, Barbados, Belize, Benin, Chad, Jamaica, and Kenya—have formally notified the Secretary-General of their intention to contribute personnel to the MSS mission, while additional countries have expressed interest in doing so but have not yet provided official notification to that effect. As at late April, the UN-administered trust fund for the mission had received $18 million in contributions from Canada, France, and the US.
The US is the mission’s main financial backer and has pledged a total of $300 million in financial, logistical, and material support. The disbursal of a large portion of those funds has been held up in the US Congress, however. On 12 April, the administration of US President Joe Biden
released $60 million to support the mission and the Haitian National Police (HNP) under a legal provision known as the Presidential Drawdown Authority. On 19 June, media outlets
reported that the administration would override the congressional hold and release a further $109 million.
