给你看 所罗门群岛 和 澳大利亚 2017 年签的条约,其实只要在所罗门群岛政府规定好 Area of Operations 的情况下也没问题:
(1) Members of a Visiting Contingent and all Assets shall enjoy freedom of movement throughout the Area of Operations.
(2)
A Visiting Contingent shall have the unimpeded right to the use of roads, bridges, canals and other waters, port and airfield facilities and airspace without payment of dues, tolls or other charges or fees throughout the Area of Operations.
(3) Members of a Visiting Contingent may possess, store and operate Assets without a permit or licence or restriction and free of duties, taxes and charges.
(4) A Visiting Contingent shall not be required to register or obtain licences for the use of Assets under applicable Solomon Islands Laws.
(5) Where members of a Visiting Contingent are required to use vehicles, vessels, aircraft, or other equipment of Solomon Islands, in carrying out their duties, the use of those vehicles, vessels, aircraft and equipment shall be provided free of charge, unless otherwise mutually determined between the Parties.
