Leading South Korean mobile operator SK Telecom will build a trial network in South Korea based on China's TD-SCDMA 3G mobile telecommunications standard.

China's National Development and Reform Commission, which made the announcement yesterday on its website, said that SK Telecom would use the standard to develop 3G applications.

In addition, the commission said that Chinese and South Korean firms would establish a joint TD-SCDMA research and development centre in China, but failed to reveal the total investment in the network or the centre.
