record of achievement

Caltex began operating in South Korea in the late 1960s, just as the country was developing its economic strength. Recognizing South Korea’s growing demand for petroleum products, Caltex entered a joint venture in 1967. The partners formed the Honam Oil Refinery Co. Ltd., which built the nation’s second refinery in Yeosu, at the southern edge of the Korean Peninsula. GS Caltex is one of the largest and oldest joint ventures in South Korea between a foreign company and a Korean company.

In addition to refinery expansions, GS Caltex extended its presence into the South Korean petrochemicals business.

GS Caltex also began operating a network of service stations, which quickly gained a substantial share of Korea’s automotive gasoline business.

  • Order of Industrial Service Merit, Gold Tower (2014), from the government of the Republic of Korea
