Global trade and interdependence

Look around your room. The phone might be assembled in CHINA. The shoes might be made in VIETNAM. The coffee in the kitchen probably came from BRAZIL or COLOMBIA. The watch on the shelf might say "Swiss Made". No single country grew, mined, or built every item near you. That is because every country trades with other countries — and that giant web of buying and selling between nations is called GLOBAL TRADE.

Why countries trade — nobody has everything

Countries trade because no country has every climate, every mineral, every factory, and every skill. Saudi Arabia has a LOT of oil but cannot grow much food in the desert. Iceland has cold weather and fish but cannot grow bananas. Switzerland is great at making watches but has no rubber forests. So countries swap what they have plenty of for what they cannot make themselves. Trade lets every country get more goods than it could ever produce alone.

Imports and exports — IN and OUT

IMPORTS are goods that come INTO a country from somewhere else — a country IMPORTS what it buys from abroad. EXPORTS are goods that go OUT of a country to other countries — a country EXPORTS what it sells abroad. The same crate of bananas is an EXPORT for Ecuador and an IMPORT for the USA. The two words are just two views of the same shipment, depending on which country you are standing in.

• IMPORT = comes IN to your country (you BUY it from abroad).
• EXPORT = goes OUT of your country (you SELL it to abroad).
• A ship of coffee leaving Brazil is a Brazilian EXPORT.
• That same ship arriving in the USA is a US IMPORT.

Specialization — countries do what they do best

Most countries SPECIALIZE in a few things they are very good at — a climate that suits a crop, a skill passed down for generations, or a mineral they have a lot of. They make MORE than they need of those, sell the extra abroad, and use the money to buy what they cannot make as well. Brazil specializes in COFFEE. Switzerland specializes in WATCHES and CHOCOLATE. Saudi Arabia specializes in OIL. Japan specializes in ELECTRONICS and CARS. France specializes in WINE and CHEESE. China specializes in MANUFACTURED GOODS — phones, clothes, toys, machines.

1. BRAZIL — warm, wet climate is perfect for COFFEE beans.
2. SWITZERLAND — long tradition of fine WATCHES and chocolate.
3. SAUDI ARABIA — huge oil reserves under the desert.
4. JAPAN — world-leading factories for ELECTRONICS and cars.
5. CHINA — massive factories for MANUFACTURED goods of all kinds.
6. FRANCE — famous vineyards and dairies make WINE and CHEESE.

Interdependence — countries depend on each other

Because every country imports some things and exports others, countries become INTERDEPENDENT — they DEPEND on each other. The USA depends on Saudi Arabia for some of its oil. Saudi Arabia depends on the USA for technology and machines. Japan depends on Australia for iron ore; Australia depends on Japan to buy that ore and turn it into cars. If a big trading partner has a flood, a strike, or a war, the shelves on the other side of the world feel it within weeks.

How a global supply chain works

A single product often touches many countries before you buy it. A smartphone might use minerals mined in CHILE, a screen made in SOUTH KOREA, a chip designed in the USA and built in TAIWAN, software written in INDIA, and final assembly in CHINA — all to land in a shop in MALTA. That long chain is called a GLOBAL SUPPLY CHAIN. It only works because countries trust each other enough to keep trading, and ships, planes, and trucks keep moving across borders every single day.
