28. 公务差旅拟议经费为 4 220 500 美元，与 2017/18 年度分配数相比减少 272 300 美元(6.1%)。所需资源包括用于任务区以外非培训类差旅经费的 1 859 000 美元。行预咨委会从手头资料中注意到，一些拟议差旅将由多人多次前往同一目的地。行预咨委会认为，一些拟议差旅可以合并，或减少出差人员人数。因此，行预咨委会建议，将任务区以外非培训类差旅拟议资源减少 10%(185 900 美元)。行预咨委会重申，必须遵守预购政策指示并审慎地使用公务差旅资源(见 A/72/7/Add.44，第 4 和 7 段)。
28. The proposed resources for official travel amount to $4,220,500, representing a decrease of $272,300, or 6.1 per cent, compared with the apportionment for 2017/18. The requested resources include an amount of $1,859,000 for non-training travel outside the mission area. The Advisory Committee notes from information provided to it that a number of the proposed trips are to be undertaken by multiple travellers and for multiple visits to the same destination. The Committee is of the view that a number of the proposed trips could be consolidated or undertaken with fewer travellers. Therefore, the Committee recommends a reduction of 10 per cent, amounting to $185,900, to the proposed resources for non-training travel outside mission area. The Committee reiterates the need for compliance with the advance purchase policy directive and judicious utilization of official travel resources (see A/72/7/Add.44, paras. 4 and 7).
