Despite being banned in Mainland China, Twitter has opened its office in Hong Kong, in what is speculated as an attempt to keep the doors open for business in the country.

The Hong Kong office will be headed by Twitter executive Peter Greenberger, with the company expecting to tap China for advertising revenue.

It also highlighted its intention to help Chinese businesses connect with foreign users instead of just focusing upon the domestic market.

South China Morning Post cited Twitter’s Asia Pacific VP Shailesh Rao as saying: "We’re capitalising on this growing trend where the most ambitious, entrepreneurial and successful Chinese companies want to go global, and we believe that Twitter is an essential way for them to connect and engage with the world."

"Opening our Hong Kong office now and hiring a sales team to work directly with advertisers across the Greater China market will contribute to our next phase of growth in Asia."

China blocked the micro blogging site along with Facebook in 2009 as Chinese authorities believe that the netizens could use the platform to spark anti-government protests like the "Arab Spring" uprisings in the Middle East.

However, Chinese tech giants including Huawei and the Xinhua news agency, use the microblogging site to reach their global audience.
