What is an international transportation?

Any carriage in which, according to the contract made by the parties, the place of departure and the place of destination, whether or not there be a break in the carriage or a transshipment, are situated either:

1. Within the territories of two High Contracting Parties; or

2. Within the territory of a single High Contracting Party, if there is an agreed stopping place within a territory subject to the sovereignty, suzerainty, mandate or authority of another Power, even though that Power is not a party to the Convention. (Art. 1[2])

Note: A High Contracting Party is one of the original parties to the convention.
