On this day, 40 years ago, on December 29, 1985 (November 18, 1985 in the lunar calendar), Ivory Coast changed its name to "Cote d'Ivoire." On December 29, 1985, the Republic of Côte d'Ivoire decided to change its name to the Republic of Cote d'Ivoire from January 1, 1986. "Cote d'Ivoire" is a Chinese transliteration of French "Ivory Coast." The reason why "Ivory Coast" was renamed "Cote d'Ivoire" is that its name has always been a paraphrase in various languages, resulting in the initial letter of the word "Ivory Coast" being different in various languages. Due to the fact that international institutions implement the order of the first letter of each country's names in the alphabet, the position of Ivory Coast's name arrangement changes in many cases. With the consent of the United Nations, starting from January 1, 1986, the name of this country was changed to transliteration in all languages.
