The Hong Kong-born creative, who worked on the Evian, Intel, New Balance and Volvo accounts at Euro from 2001 to 2003, has won major awards at Cannes, One Show, Communication Arts, Kelly Awards and Art Director's Club.
He spent the last six years at Euro, joining the agency's New York operation as senior writer in 1998.
Prior to that, he was at Marchfirst in Portland, Chiat/Day in Los Angeles and McCann-Erickson in Los Angles.
According to Cheung, his return to Hong Kong was fueled by a desire to work on local brands, on which he expects to be afforded greater creativity.
"I had been in New York for more than five years. I miss it dearly, but working on mostly large brands for large clients can be difficult as they are very set in their ways. Hong Kong is different because in Asia there are all types of brands including those that are not mature yet. Client marketers also give you more room to be creative here," said Cheung.
At TBWA Hong Kong, Cheung said he would work on the Hutchison's 3, as well as Papyrus and Pacific Place accounts.
He added: "For bigger clients there are nice pockets of work, but my job will be to increase the batting average, making the work consistently better."
Neil Ducray, managing director at TBWA, added that Cheung - who has 15 years' experience - would bring a unique perspective to the agency's creative team.
"James is someone who can walk on both sides, gweilo and Chinese. He's equally comfortable thinking in a western and Chinese way, having grown up in Hong Kong. He understands Hong Kong as a native, and that he made it in New York shows that he can make it anywhere," Ducray said.
"With James, TBWA now has a strong team in place on a senior management level. We are in the process of finalising a new planner who will be coming on board shortly."
