Some countries, such as Britain in the 19th century and Chile and China in recent decades, have implemented unilateral tariff reductions – reductions that have been made independently and without contrary action by other countries. The advantage of unilateral free trade is that a country can immediately benefit from the benefits of free trade. Countries that remove trade barriers alone do not need to postpone reforms while trying to convince other nations to follow suit. The benefits of such trade liberalization are considerable: several studies have shown that incomes are rising faster in countries that are open to international trade than in countries that are more closed to trade. Dramatic examples of this phenomenon are the rapid growth of China after 1978 and India after 1991, with data indicating when major trade reforms took place. These are located between countries located in a given region. Among the most powerful are a few countries close in a geographical area.  These countries generally have similar hisisms, post-D demography and even economic goals. IMF member countries are helping to set up a pool of loans in the event of balance-of-payments problems.
The reason for this regime is that private international capital markets operate imperfectly and that many countries have limited access to financial markets. In the absence of access to IMF financing, many countries can only correct significant imbalances in international payments through drastic measures that can have a negative impact on their own economies and the world`s economies. The IMF provides other sources of financing to countries in difficulty that would not otherwise be available to them. The following video details and compares the different types of trade agreements: Regional trade agreements are trade agreements between two or more partners (nations). Almost all countries are part of at least one ATR. In an RTA, countries are “squatting” and forming an international community that facilitates the exchange of goods and services between them. For example, the North American Free Trade Agreement (NAFTA), which was implemented between Canada, the United States and Mexico, facilitates trade between these countries by reducing tariffs and eliminating tariffs. The Association of Southeast Asian Nations (ASEAN), see below, provides for free trade, services, labour and capital in ten independent member countries to ensure a balance of power for China and Japan. The Central American Free Trade Agreement (CAFTA) (Costa Rica, Dominican Republic, Guatemala, Honduras, Nicaragua and El Salvador) eliminated tariffs on more than 80% of the United States.
