Safeguard measure, as one of the trade remedy measures, is known as the“safety valve”of free trade. Most free trade agreements and regional trade agreements have stipulated the provisions of safeguard. Many FTAs directly invoked the provisions of safeguard measure from WTO legislation, but FTAs also have their special rules on safeguard measure. It’s necessary to compare the safeguard measure under WTO and FTA, so as to summarize the characteristics and contents on safeguard in the legislation of FTA, and give further impetus to the developments of safeguard measure and legislation in China FTA.
