analysis: The text appears to be discussing international law and treaties related to environmental protection, specifically pollution by dumping and the regulation of the territorial sea and continental shelf. The mention of "environnental lar" and "pollutlon by dunplng" suggests a focus on environmental issues. Additionally, the reference to "the Convention" and "multilateral instruments" implies a discussion of international agreements and treaties.
