Innocent passage
Innocent passage is a concept in the law of the sea that allows for a vessel to pass through the territorial sea (and certain grandfathered internal waters) of another state, subject to certain restrictions.
Innocent passage applies to the entire territorial sea, up to at most 12 nautical miles (22 km; 14 mi) from coastal baseline. Transit passage is a similar right that applies only to straits that divide two areas of international waters; it has different requirements for transiting vessels. Freedom of navigation is a general right enjoyed in international waters; "freedom of navigation operations" enforces this right, in some cases to counter a claim by a sovereign state that certain waters are territorial.
