Extended data:

International trade law regulates two kinds of relations;

One kind is the international relationship of commodity buying and selling itself, the content of which is the rights and obligations of buyers and sellers in the transaction, which is manifested as the contractual relationship of international commodity buying and selling. The norms of this relationship are specially adjusted and belong to the norms of international trade law.

The other is the relationship attached to international commodity trading, which is indispensable to the realization of international commodity trading, but it is not a commodity trading relationship in itself, including:

(1) The transportation relations in the international sale of goods include the sea, air, rail, road, river and other transportation relations of international goods, including the rights and obligations of the shipper (or consignor), consignee and carrier in various bills of lading, air, rail and road transportation.

(2) The insurance relationship in the international sale of goods includes the insurance relationship in the transportation of goods by sea, land and air, and covers the rights and obligations between the insurer and the insured in the international transportation insurance policy (see Insurance Law).
