1. In order to better protect human health, Parties are encouraged to implement measures beyond those required by this Convention and its protocols, and nothing in these instruments shall prevent a Party from imposing stricter requirements that are consistent with their provisions and are in accordance with international law.
2. The provisions of the Convention and its protocols shall in no way affect the right of Parties to enter into bilateral or multilateral agreements, including regional or subregional agreements, on issues relevant or additional to the Convention and its protocols, provided that such agreements are compatible with their obligations under the Convention and its protocols. The Parties concerned shall communicate such agreements to the Conference of the Parties through the Secretariat.
