Nelson Bostock Asia will open for business on 1 August with Taiwan-based smartphone designer HTC the first client on its books.
The UK agency is ranked fifth in the PRWeek tech consultancy table 2011 - and is the last agency in the top five to open an office in the Asian market.
Bite has a 55-strong team in Asia; Edelman has Hong Kong and Taiwan offices; the Hotwire Group expanded into Asia in May 2010 and Brands2Life has a network of independent agencies in the region.
Nelson Bostock's office, based in Hong Kong's Times Square, will be headed up by the agency's current head of mobile, Aparna Aswani, who is relocating from the UK. She will report to Nelson Bostock Group MD Lee Nugent. The agency has started recruiting employees in Hong Kong and another member of the London office will relocate.
Chairman Martin Bostock said: 'We hope the initial move to target technology clients will lead to growth in the consumer market too. HTC, for example, started as a pure tech client and it's grown into a well-known consumer brand.'
Bostock added: 'We can offer our existing UK and US clients the opportunity to promote their brands in the Asia-Pacific market. And once we build some Asian clients up we can help their introduction into European and US sectors.'
