The company’s operations span eight sectors, in which the Charoen Pokphand Foods (CPF)’s food and agricultural products segment has grown the most, making it the world’s largest producer of feed, shrimp, and a global top three producer of poultry, pork, among other agricultural produces. In the telecommunications sector, CP Group’s subsidiary, True Group, is one of the largest telecommunications companies in Southeast Asia with over 25 million mobile customers.

Charoen Pokphand traces its beginnings back to 1921, when immigrant brothers Chia Ek Chor and Chia Jin Hyang, hailing from Shantou, China, started a seed store named Chia Tai Chung on Songsawat Road in Bangkok’s Chinatown during the reign of King Rama VI. They imported seeds and vegetables from China and exported pigs and eggs to Hong Kong, Taipei, Kuala Lumpur, and Singapore. By the 1950s, the shop began to specialize in exporting animal feed, particularly for chickens but the business struggled until the 1970s when the Bangkok Bank asked it to assume control of a bankrupt chicken farm. 

In the 1980s, the CP Group expanded internationally exporting their contract farming formula across Southeast Asia and around the world to Mexico, Taiwan, Portugal, Mainland China, Indonesia, Turkey, and the United States. In 1989, CP entered the petrochemical business with Solvay of Belgium to launch Vinythai Co., a manufacturer of polyvinyl chloride. In 1990, the CP Group acquired a stake in TelecomAsia, a joint venture with US telecommunications firm NYNEX to build and operate two million telephone lines in Bangkok worth some US$3 billion.

Since 2002, the company has invested in countries such as China, the UK, Taiwan, and Southeast Asia’s counties and is currently operating businesses in the field of production and distribution of animal feed as well as aquaculture, chilled products, poultry farming, etc. In addition, the company also established many subsidiaries such as CP Fresh Mart, CP Kitchen, CP Fresh Mart, and CP Food World.
