In fact, the exchange of goods across borders goes back to 2500 BC. Archaeologists have found that the Sumerians in the northern Mesopotamia (Iraq) enjoyed great prosperity due to the maritime trade in textiles and metals.
It should be known that international contracts are made and carried out in three main ways:
In fact, it is called an international contract that at least one of its components has an international character. Now this component may be one of the parties to the contract or may be both parties to the contract, it may be that the transaction is outside the respective borders or that the place of execution of the contract is outside the borders.
In the 1966 report of the Secretary General of the United Nations, "International Trade Laws" refers to the set of rules and regulations that administrate those trade relations, while having the nature of private law are related to different countries. Therefore, international relations or contracts go beyond national borders and as a result more than one country is involved in it.
Another thing is that international trade law includes those topics that have the nature of private law, so as a result it does not include topics of the nature of public law that are related to governments and only includes persons of business.
Some of the topics of international trade or international contracts are as follows:
Agency contracts and other exclusive sales arrangements, negotiable instruments and bank commercial credits, insurance, contracts related to sea, air, road or rail transportation, industrial property and copyright, and international commercial arbitration. These are only a part of the issues related to international trade, which are administrated by the domestic laws of countries and international conventions including the 1980 Vienna Convention on International Sales.
