What were the rights of neutral ships under the international law?

Under international law, neutral ships have the right to navigate freely on the high seas without interference from belligerent states. They are entitled to protection from being attacked or seized, as long as they do not engage in unlawful activities, such as carrying contraband or aiding one of the warring parties. Additionally, neutral ships should not be subject to blockades unless properly notified. These principles are grounded in customary international law and various treaties, including the Hague Conventions.
