Following this contribution, we will look at “real-world” trade in the light of these two factors that influence trade policy and see what this means for the UK`s trade efforts. At the international level, there are two open access databases that have been developed by international organizations for policy makers and businesses: a free trade agreement is a set of rules on how countries deal with each other when it comes to doing business together – importing and exporting goods, services and investments. A fundamental principle for New Zealand is that any outcome in terms of services and investment must protect our government`s right to regulate for legitimate public policy purposes. Free trade agreements can facilitate visa access for New Zealand businessmen and our trading partners, which supports the development of our trade and economic relationships. Since WTO members are required to communicate their free trade agreements to the secretariat, this database is based on the official source of information on free trade agreements (called the WTO-language regional trade agreement). The database allows users to obtain information on trade agreements that are communicated to the WTO by country or theme (goods, services or goods and services). This database provides users with an up-to-date list of all existing agreements, but those that are not notified to the WTO may be lacking. In addition, reports, tables and graphs containing statistics on these agreements, including preferential tariff analysis, are presented.  As soon as the agreements go beyond the regional level, they need help. The World Trade Organization intervenes at this stage.
This international body contributes to the negotiation and implementation of global trade agreements. The second way of looking at free trade agreements as public goods is related to the growing trend that they are “deeper”. The depth of a free trade agreement relates to the additional types of structural policies it covers. While older trade agreements are considered more “flat” because they cover fewer areas (for example. B tariffs and quotas), recent agreements cover a number of other areas, ranging from e-commerce services and data relocation. Since transactions between parties to a free trade agreement are relatively cheaper than those with non-parties, free trade agreements are considered excluded. Now that deep trade agreements will improve the harmonization of legislation and increase trade flows with non-parties, thereby reducing the exclusivity of free trade agreements, next-generation free trade agreements will take on essential characteristics for public goods.  The General Agreement on Tariffs and Trade (GATT 1994) originally defined free trade agreements that were to include only trade in goods.
 An agreement with a similar purpose, namely the improvement of trade in services, is referred to as the “economic integration agreement” in Article V of the General Agreement on Trade in Services (GATS).  However, in practice, the term is now commonly used [by whom?] to refer to agreements that concern not only goods, but also services and even investments. Environmental provisions have also become increasingly common in international investment agreements, such as free trade agreements. :104 Subsequently, the volume of world trade declined by about 50% in the 1930s, impoverishing producers and the world`s population.
