When looking at coastal areas contiguous with those of other countries, it is important to present information on transboundary pollution and data from reports not only by the country currently preparing its report but also other countries along the coast.
Dans le cas de zones côtières jouxtant le territoire d'autres pays, il est important de fournir des renseignements sur la pollution transfrontière concernant non seulement le littoral du pays auteur du rapport, mais aussi celui des autres pays riverains.
