What are the various ways in which countries can be linked?
Countries can be linked through various ways. First, they are connected through the movement of goods and services via foreign trade, which integrates markets across different countries. Producers in different nations closely compete with each other through this trade.
Second, countries are linked through foreign investment, where capital flows between nations. The movement of technology also connects countries as it moves across borders.
Third, countries can be connected through the movement of people between nations. People usually move from one country to another in search of better income, better jobs, or better education. However, this movement has not increased much in recent decades due to various restrictions.
Explanation
The textbook explicitly mentions multiple ways countries can be linked: (1) movement of goods and services through foreign trade, (2) movement of investments through foreign investment, (3) movement of technology, and (4) movement of people. The context clearly states 'Besides the movements of goods, services, investments and technology, there is one more way in which the countries can be connected. This is through the movement of people between countries.' This comprehensive answer covers all these aspects for full marks.
