Datang Telecom Technology & Industry Holdings Co, a major developer of the home-grown TD-SCDMA 3G standard, is in talks with the country's national pension fund to sell the latter a 20 percent stake through a private placement in a deal worth as much as 3 billion yuan, company sources said.

Datang Telecom Holdings is a subsidiary of Datang Telecom Group, one of the country's leading telecom equipment makers, known for its development of TD-SCDMA 3G mobile standard.

"The two sides are nearing wrapping up their deal but they have not yet decided on the price tag," a person close to Datang said.
