1. The Republic of Malawi understands and declares that the provisions of the Convention, including those concerning equitable and reasonable utilisation (Articles 5–6), the no-harm rule (Article 7), the obligation to notify (Article 12), and the duty to cooperate (Article 8), are procedural and substantive obligations that govern the exercise of Malawi’s sovereign rights over its internationally shared watercourses.

2. The Republic of Malawi declares that nothing in the Convention, including the definition of ‘international watercourse’ in Article 2, shall be interpreted as implying any determination on the question of boundary delimitation of Lake Malawi or any other water body adjacent to an international boundary. Malawi’s participation in any notification, consultation, or data-sharing process under the Convention with respect to Lake Malawi shall be without prejudice to its territorial and boundary positions in relation to that lake, and shall not constitute an admission or waiver of any kind in respect of those positions.
3. The Republic of Malawi further declares that the reference in Article 5(2) of the Convention to ‘participation’ of watercourse States in the use, development, and protection of an international watercourse shall be understood as participation on the basis of Malawi’s sovereignty and sovereign rights within its territory, and shall not be construed as conferring on any other State any rights over waters, the bed, or the subsoil of Lake Malawi beyond what is recognised under applicable bilateral arrangements and international law.
4. The Republic of Malawi notes that, in accordance with Article 3 of the Convention, this Declaration supplements and is consistent with any applicable bilateral watercourse agreement to which Malawi is or may become a party, and that the principles of this Declaration shall apply mutatis mutandis to any framework agreement or joint management mechanism established pursuant to the Convention in relation to Lake Malawi or any other internationally shared water body.
5. This Declaration is made in a spirit of cooperation and in recognition of Malawi’s commitment to the peaceful, equitable, and sustainable management of its shared water resources, and shall in no way be construed as a hostile or contentious act towards any co-riparian State.
