Final answer:
International trade plays an important role in economic and social development, especially for developed countries. The Trade and Development Index measures a nation's social and economic development, with developed countries ranking higher. East Asia and Pacific countries perform well in the index.
Step-by-step explanation:
International trade has a significant role in influencing nations' economic and social performance. While trade can bring benefits to both developed and developing countries, it is especially important for the economic development of developed countries.
The Trade and Development Index (TDI) attempts to provide a quantitative indication of a nation's social and economic development. However, it is important to note that the 30 highest-ranked nations in the initial TDI were all developed countries.
Among developing countries, the countries of the East Asia and Pacific region had the best regional performance in the Trade and Development Index.
