International trade is when goods are sold by firms or governments in one country to customers in another country.  International trade is very important to the economies of almost every country in the world.  It is also very controversial.

For example, many goods bought in the US are made in China.  Many people are unhappy about this because they feel trade takes jobs away from Americans and gives them to Chinese.

Economists, however, believe that trade is good for all countries involved.  They say it allows people in all countries to get more goods for lower prices than they otherwise would.
