It has BPO facilities in Manila, in the Philippines, and Chennai and Trivandrum in India, which have also expanded recently, apart from three sites in Sri Lanka.
"The expansion is happening because of new clients and the expansion of existing clients," Sinha told a news conference in Colombo.
The US-based firm provides transaction processing and financial services to clients mainly in the US and the United Kingdom, said Devapriya Perera, senior vice president and head of R R Donnelley's operations in Sri Lanka and Trivandrum.
"The market for outsourcing is so huge - we've roughly exploited only about 25 percent of the world market," he said. "There's enough work to go after."
Perera said the opportunity to expand came with the end of the island's 30-year ethnic war in May 2009.The company's BPO operations are considered the oldest in the island having been set up under another name in 1983 when the war intensified.
