for example Japan is advance in the field of consumer electronics so countries like USA directly purchase goods from them and also learn about the new technology is being discovered on the other side of the world.

In some countries have lots of labours but don’t have resources so take resources from another countries make the industries in own countries it will economic growth to both countries & most important it reduce the employment problem.

For example in India Reliance petroleum industries get the resources in UAE & USA use the Indians manpower to run the industries.

Different countries use different currencies, in the international trade involves an exchange of currencies .It takes place to foreign exchange market ,it may chance to increase the currency value.

One product can produce lower opportunity cost compare to the other countries.

Yet another important reason is if country believe in one economy if it collapses, the country will fall. If trading internationally , country economy will balance because it relay on one country to another countries so it creates balance amongst them.

Disadvantage of international Trade:

One country dealing with most of the countries if that country fall in economic it suffer all dealing countries.

For example recently economic collapse in European union.

It slightly reduce the own country cultural identity .

For example Coco-Cola, mc donalds ,Star Bucks, Pizza hut , Western Cloths all sell products that symbolize American values & it reflect American corporate culture it reduce the own country identy.

Some political problem, rules & government change in act it affect the international trade.

For example two countries start a war the countries applied trade barriers like (Vietnam & USA) practiced but it removed in 2001.

Protectionism:

The protectionism means the country want to protect with global competitors. The country want to develop own domestic market .It is usually politically motivated.

In domestic view of global trade indicates why most nations of the global are inclined to implement in trade protection policies.becauses all nation want to exports exceeding the imports,they are inclined to implement policies that restrict imports & promote exports.mostly government use three trade policies are tariffs,guotas and subsidies.They are givien below.

TARIFFS: Commonly used trade policy is the tariffs it is simply taxex applied for imports.Taxes value is added to the import goods price government force the importers to sell the products with tax included price rate . For example in USA Ferrari 458 italia price is USD$ 225,325 we want to import this car in India need to spend USD$ 471,454 the difference is USD$ 246,129 it is import tax pay to Indian government.

The importers goods price is high compare to the domestic good so people want to buy the domestic goods because of the lowest price.moreover domestic producers can also increases the price they charge their goods.

QUOTAS: An alternative of tariffs is to simply reduce the quantity of imports coming in a country.Technical term for this is an import quota.The government only allow to specific number of products for imports & sell in domestic economy .mostly domestic producers would likely prefer the import quota at zero,preventing the all foregn imports any restriction is appreciated with fewer imports entering the domestic economy,more domestic production is sold,and in all likehood, at higher prices.

SUBSIDIES: A third policy is for the domestic government to subsidize a domestic industry facing cometition from imports that means government pays the domestic producers for each goods they produced. It is simply payments got from the government to the business or indivduals without any expectation of receving any production in exchange. Domestic producers usually encorage he use of government subsidies through competitive with lower cost foreign imports. It useful to domestic producers produce therir good at lower price presumbly it reduce number of imports into the country.
