International marketing involves identifying consumer needs abroad and satisfying them better than competitors while considering the firm's internationalization stage and global environment. The key elements of the international marketing mix are product, price, place, and promotion. Compared to domestic marketing, international marketing differs in factors like dealing with multiple currencies and cultural differences, obtaining foreign market research, and defining market segments across countries. International marketing coordinates marketing activities worldwide while multinational marketing means marketing across national borders. Reasons for marketing abroad include economies of scale, saturated domestic markets, high R&D costs, and new trade opportunities.
