When Siemens came to Korea for the first time in the 1950s, its mission was to help rebuild the war-torn country through projects to install power generation facilities, chemical plants, cement factories and cables. About a half-century after the opening of Siemens liaison office here in 1967, Korea has grown to become one of the world s top 10 economies, playing major roles in the international community. As one of the contributors to Korea s economic development, the German company s local subsidiary is now making all-out efforts for the Asian country to host the World Expo 2030 in its second-largest city, which is also a base for Siemens infrastructure business here.
