Paraphrasing (23rd paragraph)
Text
The question of sanctions in MEAs is a complicated one and often misunderstood. Although over 20 MEAs provide for recourse to trade measures, none of these is a trade sanction in the same way that the WTO uses them. In CITES for example, trade measures are the instrument of the treaty; it is about trade. In the Montreal Protocol, trade measures can be used purposively to control the flow of ozone- depleting technology. Fishery treaties also call for trade measures but only as a means of achieving the purpose of the treaty. These trade measures are predicated on an entirely different principle than the trade measures that the WTO employs in the DSU when it authorizes one country to sanction another.
The main idea of the paragraph
Other international bodies employ trade measures just as a tool to achieve the goal of the relevant treaties, not for the same purpose for which the WTO uses them as it authorizes one nation to sanction another.
其他一些国际机构在采取与贸易有关的措施时只是把它作为实现相关条约目标的手段, 其目的不同于世贸组织采用贸易措施的目的，不同于它授权一国制裁另一国时的目的。
