VERs are generally implemented for exports from one country to another. VERs have been in use at least since the 1930s and are used on products ranging from textiles and footwear to steel, machine tools and automobiles. In the 1980s, they became a popular form of protection; they did not violate the provisions of the countries in force under the General Agreement on Tariffs and Trade (GATT). Following the GATT cycle that ended in Uruguay in 1994, members of the World Trade Organization (WTO) agreed not to introduce new VERs and to terminate existing ERVs over a four-year period, with exceptions that could be granted to one sector in each importing country. VERs first appeared in the 1930s and gained a lot of popularity in the 1980s, when Japan used one to limit car exports to the United States. The Japanese auto industry has responded by building assembly plants or “transplants” in the United States (particularly in the southern states of the United States, where there are right-to-labor laws, unlike Rust Belt countries with established unions) to produce mass vehicles. Some Japanese manufacturers that had their graft assembly plants in the Rust Belt, like Mazda.B. Mitsubishi, had to enter into a joint venture with a Big Three manufacturer (Chrysler/Mitsubishi, which became Diamond Star Motors, Ford/Mazda, which became AutoAlliance International). GM founded NUMMI, which was initially a joint venture with Toyota, which then grew to a Canadian subsidiary (CAMI) – a GM/Suzuki that was consolidated and became a geographic division in the United States (its Canadian counterparts, Passport and Asuna, were ephemeral – Isuzu-autos produced during this period were sold in captivity). The Japanese Big Threes (Honda, Toyota and Nissan) have also started exporting larger and more expensive cars (soon among their newly created luxury brands like Acura, Lexus and Infiniti – luxury brands have detached themselves from their mass-marketed parent brand) to earn more money with a limited number of cars. Some examples of VERs appeared in Japanese automotive exports in the early 1980s and in textile exports in the 1950s and 1960s. As part of the Voluntary Export Restriction (VE), this is a voluntary expansion of imports (VIE) that changes a country`s economic and trade policy to allow more imports by reducing tariffs or reducing quotas. COUNTRY is often part of trade agreements with another country or is the result of international pressure.
A voluntary export restriction (VT) or voluntary export restriction is a government-imposed limit on the quantity of a class of products that can be exported to a particular country for a period of time. They are sometimes referred to as “export visas.”  A voluntary export restriction (VER) is a trade restriction on the quantity of a product that an exporting country is allowed to export to another country. This limit is set by the exporting country itself.
