Abstract
Discussions in the Telecommunication Standardization Sector of the International Telecommunication Union (ITU-T) on standardization of optical transmission systems and devices are described as exemplifying relationships between strategies on international standardization and intellectual properties, diplomatic aspects of international standardization, and corporate R&D strategy as related to standardization. Standardization activities involve coordination processes to attain common understanding among parties with different histories, value systems and cultures. The 500-year history of standardization in Europe provides a plenty of lessons for the Japanese, who have limited experience in this field, to learn. Since the practice and skill of arriving at agreement between different opinions through dialog are a prerequisite of internationalization both at personal and national levels, international standardization activities should provide us valuable information as well as an opportunity of learning.
