……. If one is to succeed, one will need a mastery of English because it is the language of business, science, diplomacy and academia.
…… English is the common language of the world and the Internet. However, we must not lose our basic strengths, the vitality of our original cultures and languages.

The growth of English was due in part to the British colonization from the 16th to the 19th centuries. Another reason offered is the popularity of American movies. A major reason for the popularity of English is that it is the language of the USA, a global economic superpower and a leader in higher education.
