Twitter Inc has established an office in Hong Kong to target Chinese advertisers who plan to expand overseas.

The online social networking provider's first site in China will provide online and mobile ad services to local brands across the country and bring Twitter a new source of ad revenue.

The office reflects the increasing demand in China for the services that this type of social media platforms offers, said Thomas Crampton, who directs the social media campaign program at advertising company Ogilvy &Mather.
