; and (D) in the contiguous zone of a coastal State, the State may— (i) exercise the control necessary to prevent the infringement of its customs, fiscal, immigration, or sanitary laws and regulations within its territory or the territorial sea; and (ii) punish the infringement of those laws and regulations committed within its territory or the territorial sea. (4) Customary international law, in its current form, as provided for in the United Nations Convention on the Law of the Sea, recognizes that outside the territorial waters of a coastal State, the vessels and aircraft of all countries enjoy the high seas freedoms of navigation and overflight. Pursuant to those freedoms and the requirements of international law— (A) before boarding a vessel outside of the territorial waters of a coastal State, but within the contiguous zone of that State, authorities of the State are generally required to have reasonable grounds to believe that the vessel is destined for the State or has violated or is attempting to violate the customs, fiscal, immigration, or sanitary laws and regulations of that State; and (B) the hot pursuit of a foreign vessel— (i) may be undertaken when competent authorities of the State have good reason to believe that the vessel or one of its boats has violated the laws and regulations of that State; (ii) is required to be commenced when the foreign vessels or one of its boats is within the internal waters, the territorial sea, or the contiguous zone of the State, and may be continued outside the territorial sea or the contiguous zone only if the pursuit has not been interrupted
