Nations gain from International Trade in multiple ways. It is mutually beneficial to nations as it leads to regional specialisation and a higher level of production. Through trade, nations can achieve a better standard of living and ensure the worldwide availability of goods and services.

International trade also promotes equalisation of prices and wages across nations. Additionally, it facilitates the diffusion of knowledge and culture between trading partners, enriching societies globally.

The fundamental basis of international trade is specialisation in production. When different countries practise specialisation and division of labour in the production of commodities or provision of services, it benefits the world economy. Trade is based on the principle of comparative advantage, complimentarity and transferability of goods and services.

Foreign investment also boosts trade in developing countries that lack capital. Industrial nations, by developing capital-intensive industries in developing countries, ensure import of food stuffs and minerals while creating markets for their finished products. This cycle steps up the volume of trade between nations.

In modern times, trade forms the basis of the world's economic organisation. With well-developed transportation and communication systems, no country is willing to forego the benefits derived from participation in international trade.
