Global mobile phone operating system giant Symbian says that it will open a subsidiary in China on January 16 to replace the current China office.

According to CCID Consulting, seven mobile phone manufacturers are using Symbian's mobile phone operating system, but Nokia is the largest one, accounting for 96.5% of Symbian's total. As the recent data showing that Nokia's market share in the global intellectual mobile phone market is declining, Symbian is eager to find a way to expand into new markets.

Set up in June 1998, Symbian owns the largest share in the mobile phone operating system market. Its stock is held by Ericsson (15.6%), Nokia (47.9%), Panasonic (10.5%), Samsung (4.5%), Siemens (8.4%) and Sony Ericsson (13.1%).
