Final answer:
The reliance on imported manufactured goods in developing countries is true, reflecting their economic histories and the evolution of their trade channels. Successful economic development has been seen in countries that embraced international trade rather than those that pursued import substitution strategies.
Step-by-step explanation:
The statement that traditional channels in developing countries evolved from economies with a strong dependence on imported manufactured goods is True. Historically, many developing economies have relied on imports to meet the demand for manufactured goods, which their own industries were not equipped to produce. This dependence was often a result of the colonial period that left many countries focused on exporting raw materials while importing finished goods. Over time, these economies tried to shift towards a more balanced approach, looking inwardly to foster domestic industries through strategies like import substitution.
However, the strategy of import substitution did not always lead to successful economic development. On the contrary, many countries that kept their economies open to both imports and exports, such as those in East Asia, have shown a greater ability to progress developmentally. The success stories of Japan, China, and India, in contrast to the failures of import substitution policies, have demonstrated that participation in international trade is a potent catalyst for economic growth.
Moreover, regional trade agreements like NAFTA and the economic success of the European Union also support the idea that reducing barriers to trade is beneficial for economies. The current trend is a move away from isolation and towards greater integration into the global economy.
