What is territorial sea and high seas?

1. The territorial sea refers to the sea area with a certain width adjacent to its coast or internal water under the sovereignty of the coastal state and is an integral part of the national territory. The airspace, seabed and subsoil of the territorial sea belong to the sovereign jurisdiction of coastal countries.

2. In international law, the high seas refer to the internal waters, territorial waters, archipelagic waters and marine parts outside the exclusive economic zone that are not subject to the jurisdiction and control of any national sovereignty.

The secondary position between the territorial sea (generally 12 nautical mile) and the high seas is the exclusive economic zone (up to 200 nautical miles). For example, the central part of Miyako Strait is an exclusive economic zone (international waterway, which other countries have the right of free navigation and can pass harmlessly) and will soon reach the high seas of the western Pacific.

High seas restrictions

1, stop piracy

Piracy refers to the illegal rape, seizure or plunder of ships, aircraft, people or property by crew or passengers of ships or aircraft for private purposes on the high seas or outside the jurisdiction of any country. Piracy is an international crime.

Any country's warships, military aircraft or other clearly marked, identifiable and authorized ships or aircraft serving the government may seize pirate ships or aircraft, arrest their personnel and seize their property.

The court of the detaining country can try and punish pirates and decide on the disposal of ships, planes or property, but it should respect the rights of bona fide third parties. If there is no justifiable reason for arrest, the arresting country shall compensate for the damage or loss caused by the arrest.

Step 2 Stop the slave trade

The slave trade is an international crime. Most slaves plundered from Africa were trafficked to the United States by sea, and transporting slaves was also a crime of slave trade. Every country should take effective measures to prevent and punish slave trafficking by ships flying its flag. Any slave who takes refuge on any ship, no matter what flag the ship hangs, is of course free.

3. Unauthorized broadcasting is prohibited.

According to the provisions of the United Nations Convention on the Law of the Sea, unauthorized broadcasting means that ships or facilities broadcast radio or television broadcasts on the high seas in violation of international regulations, except for broadcasting distress signals.

In this case, anyone who broadcasts from the high seas without permission may be brought to court in the flag country, the country where the facility is registered, the country where the broadcaster belongs, any country that can receive such broadcasts, or any country where the licensed radio communication is disturbed. A country with jurisdiction may arrest any person or vessel engaged in unauthorized broadcasting and seize broadcasting equipment.
