FTAs are arrangements between two or more countries or trading blocs that primarily agree to reduce or eliminate customs tariff and non tariff barriers on substantial trade between them.
FTAs, normally cover trade in goods (such as agricultural or industrial products) or trade in services (such as banking, construction, trading etc.). FTAs can also cover other areas such as intellectual property rights (IPRs), investment, government procurement and competition policy, etc.
International Trade Law includes the appropriate rules and customs for handling trade between countries. However, it is also used in legal writings as trade between private sectors, which is not right.
This branch of law is now an independent field of study as most governments has become part of the world trade, as members of the World Trade Organization (WTO).
Since the transaction between private sectors of different countries is an important part of the WTO activities, this latter branch of law is now a very important part of the academic works and is under study in many universities across the world.
