Xalqaro savdo katta foyda keltiradi, chunki undan yuqori haqiqiy daromadlar olinadi. Insonning xalqaro savdoning ahamiyatiga bo'lgan ishonchini mustahkamlaydigan narsa — bozorlarni egallash va eski bozorlarni himoya qilish uchun buyuk davlatlar o'rtasidagi keskin kurash va qattiq raqobatdir. Ushbu bozorlarga ularning tovarlari sotiladi va ulardan xomashyo to'siqsiz import qilinadi. Xalqaro savdoning ko'plab o'ziga xos xususiyatlari, afzalliklari va natijalari bor. Xalqaro savdo yo'lga qo'yilishining asosiy sababi mamlakatlar o'rtasidagi tovarlarning nisbiy narxlaridagi farqdir. Shuning uchun har bir mamlakatda nisbiy narxlar farq qilgach, barcha mamlakatlar o'rtasida xalqaro savdo o'rnatish ularning manfaatlariga mos bo'ladi.

International trade yields a tremendous benefit due to the high real profits which are generated from it. What adds to a person’s conviction about the importance of international trade is the ferocious fighting and fierce competition between the superpowers over the acquisition of new markets and the protection of old markets, to which their merchandise is disposed of, and from which they import raw materials without obstacle. International trade has a host of distinguishing features, merits and outcomes. The main reason behind the establishment of international trade is the disparity in the proportional costs of commodities between one country and another. It would therefore be in the interest of all countries to establish international trade between them once the proportional costs differed in each country.
