Free trade is a system of trade policy that allows goods, capital, and labor to move freely between countries without the imposition of tariffs, quotas, or other trade barriers. The goal of free trade is to promote economic growth and efficiency by allowing countries to specialize in producing the goods and services for which they have a comparative advantage, and to access a wider market for their products. This in turn can lead to lower prices, increased choice and more efficient production My recommendations: h̲t̲t̲p̲s̲:̲ ̲/̲/̲ ̲w̲w̲w̲.̲d̲i̲g̲i̲s̲t̲o̲r̲e̲2̲4̲.̲c̲o̲m̲/̲r̲e̲d̲i̲r̲/̲3̲7̲2̲5̲7̲6̲/̲ ̲N̲e̲e̲r̲5̲5̲/̲
International trade is so massive and complex that every country owes at least one other country money. Some countries (like America) owe more to other countries than others (China owes very little to other countries due to their massive amount of exports). The best way to figure this out is to look at the balance of trade for each country and then find a breakdown of who that country imports and exports to.
Foreign trade is important but not necessary for a country to survive. Some countries can be self-sufficient, especially if they are not consumerist countries.
People trade internationally with other countries to import products Australians need but can't be obtained in Australia. Trading with other countries can improve relationships with another country. And some items have more quality and cost less.
Your products might be very scarce in their country, or not available at all. Some countries literally trade technology for fresh water.
Yes. Countries are interdependent on one another and lots of things happening in one country affects many other countries. So when a country rises or falls, it will affect other countries. A country may be overtaken by a rising country or may get free of a falling country. Trade may grow with a rising country, but fall with a falling country, and so affect the economy of many countries. The culture of strong countries can spread into other countries as it becomes stronger. A rising country may gain more influence and help some countries. If a powerful country falls, its friends lose some of their influence and support. So, yes the rise and fall of countries do affect other countries for many reasons and in many ways.
Sweden is itself a country. There are no other countries in it.

Although it doesn't make sense since they're both EU countries... They trade in some parts they trade with other countries, like US or SA ... And so when they get those things they trade with other parts of EU. In other words, they gain new things other parts don't have. So they pretty much trade.
Countries trade with each other because they don't have some of the natural resources that they want.
Countries trade in order to maximize their products and production. By specializing in only some of their products a country can use the limited resources in the world more efficiently!
Being landlocked is no hinderence to being a developed country. You could claim it is an advantage. A land-locked country is surrounded on all 4 sides with other countries with which it can trade. A coastal countries only has trade partners on some sides. A coastal country needs ships and ports to trade. In former times, before railways, sea and river trade was faster and cheaper than overland. This is no longer the case.
This is because some countries have or had goods that in other countries were hard to come by, so countries traded for maximum satifaction.
