The debate started in Korea in July 1998 with the publication of Ethnic Language in the Age of a Global Language(BOK),and a subsequent of the book in the Cho sun Ilbo newspaper(Yoo 2005). According to Yoo:
Bok’s main argument is that ethnic language will die out soon because people have realized the power and prestige of English as the present global language, and therefore, that the South Korean government should take the initiative to adopt English as a co-official language with Korea for the time being and, in the long run, establish English as the one and only official language in South Korea.
