三、保障措施的实施
（一）实施保障措施的目的
采取保障措施的成员方可以针对该进口产品全部或部分地中止其减让义务，或撤销或修改其减让义务。A Member shall apply safeguard measures only to the extent necessary to prevent or remedy serious injury and to facilitate adjustment. If a quantitative restriction is used, such a measure shall not reduce the quantity of imports below the level of a recent period which shall be the average of imports in the last three representative years for which statistics are available, unless clear justification is given that a different level is necessary to prevent or remedy serious injury. Members should choose measures most suitable for the achievement of these objectives.[3]
