    14. Neutral waters consist of the internal waters, territorial sea, and, where applicable, the archipelagic waters, of neutral States. Neutral airspace consists of the airspace over neutral waters and the land territory of neutral States.

    15. Within and over neutral waters, including neutral waters comprising an international strait and waters in which the right of archipelagic sea lanes passage may be exercised, hostile actions by belligerent forces are forbidden. A neutral State must take such measures as are consistent with Section II of this Part, including the exercise of surveillance, as the means at its disposal allow, to prevent the violation of its neutrality by belligerent forces.

    16. Hostile actions within the meaning of paragraph 15 include, inter alia:

    (a) attack on or capture of persons or objects located in, on or over neutral waters or territory;
    (b) use as a base of operations, including attack on or capture of persons or objects located outside neutral waters, if the attack or seizure is conducted by belligerent forces located in, on or over neutral waters;
    (c) laying of mines; or
    (d) visit, search, diversion or capture.

    17. Belligerent forces may not use neutral waters as a sanctuary.

    18. Belligerent military and auxiliary aircraft may not enter neutral airspace. Should they do so, the neutral State shall use the means at its disposal to require the aircraft to land within its territory and shall intern the aircraft and its crew for the duration of the armed conflict. Should the aircraft fail to follow the instructions to land, it may be attacked, subject to the special rules relating to medical aircraft as specified in paragraphs 181-183.

    19. Subject to paragraphs 29 and 33, a neutral State may, on a non-discriminatory basis, condition, restrict or prohibit the entrance to or passage through its neutral waters by belligerent warships and auxiliary vessels.

    20. Subject to the duty of impartiality, and to paragraphs 21 and 23-33, and under such regulations as it may establish, a neutral State may, without jeopardizing its neutrality, permit the following acts within its neutral waters:

    (a) passage through its territorial sea, and where applicable its archipelagic waters, by warships, auxiliary vessels and prizes of belligerent States; warships, auxiliary vessels and prizes may employ pilots of the neutral State during passage;
    (b) replenishment by a belligerent warship or auxiliary vessel of its food, water and fuel sufficient to reach a port in its own territory; and
    (c) repairs of belligerent warships or auxiliary vessels found necessary by the neutral State to make them seaworthy; such repairs may not restore or increase their fighting strength.

    21. A belligerent warship or auxiliary vessel may not extend the duration of its passage through neutral waters, or its presence in those waters for replenishment or repair, for longer than 24 hours unless unavoidable on account of damage or the stress of weather. The foregoing rule does not apply in international straits and waters in which the right of archipelagic sea lanes passage is exercised.

    22. Should a belligerent State be in violation of the regime of neutral waters, as set out in this document, the neutral State is under an obligation to take the measures necessary to terminate the violation. If the neutral State fails to terminate the violation of its neutral waters by a belligerent, the opposing belligerent must so notify the neutral State and give that neutral State a reasonable time to terminate the violation by the belligerent. If the violation of the neutrality of the State by the belligerent constitutes a serious and immediate threat to the security of the opposing belligerent and the violation is not terminated, then that belligerent may, in the absence of any feasible and timely alternative, use such force as is strictly necessary to respond to the threat posed by the violation.
