This reduction does not represent a cut in contributions by the US. The General Assembly negotiates the budget collectively. The budget for 2018 and 2019 will reduce the cost of the US's dues by $31.5M a year and reduce the cost of the UK's dues by $6.4M a year.
The additional reductions come mainly from across-the-board cuts in non-post resources for most departments and offices, including the Special Political Missions.
In addition the General Assembly approved the Secretary-General's proposal to move to an annual budget system on a trial basis from 2020.
