Unilateral actions to deal with environmental challenges outside the jurisdiction of the importing country should be avoided.Environmental measures addressing transboundary or global environmental problems should, as far as possible, be based on international consensus.（emphasis added）
169.Third, the United States did negotiate and conclude one regional international agreement for the protection and conservation of sea turtles: The Inter-American Convention. This Convention was opened for signature on 1 December 1996 and has been signed by five countries, in addition to the United States, and four of these countries are currently certified under Section 609. This Convention has not yet been ratified by any of its signatories. The Inter-American Convention provides that each party shall take “appropriate and necessary measures” for the protection, conservation and recovery of sea turtle populations and their habitats within such party's land territory and in maritime areas with respect to which it exercises sovereign rights or jurisdiction. Such measures include, notably, the reduction, to the greatest extent practicable, of the incidental capture, retention, harm or mortality of sea turtles in the course of fishing activities, through the appropriate regulation of such activities, as well as the development, improvement and use of appropriate gear, devices or techniques, including the use of turtle excluder devices （TEDs） pursuant to the provisions of Annex Ⅲ \[of the Convention\].
