From the early 1970s Itoh was a major supplier of synthetic yarn (polyester) to India's Reliance Industries Limited. Over the years, the close collaboration between both companies culminated in the co-promotion of a world-scale Polypropylene Project with a capacity of 250,000 tonnes per annum at a total project cost of Rs. 525 Crores, at Hazira in the State of Gujarat. With a $50 million cost for a 15 percent stake, it was at that point, the largest investment in India by a Japanese firm. Itoh also marketed products—under their own label—as diverse as a line of bicycles (mostly manufactured by Bridgestone), and computer printers. Itochu began to develop a strong information technology business in the 1980s through its subsidiary C. Itoh Techno-Science (CTC), which acted as a Japan distributor for Sun Microsystems, Cisco, Oracle and others.
