In 1895, the United Kingdom, itself on the gold standard, began issuing silver dollars, called "trade dollars," specifically for trade with the Far East. British trade dollars bore inscriptions in English, Chinese, and Malay-Arabic. Briefly during the latter 19th century, the United States issued a special trade dollar designed specifically to compete with the Mexican dollar in Far Eastern trade. The Chinese called these various silver dollars yuan, meaning "round things," and yuan became the standard monetary unit in China and modern Taiwan.
