Nokia Siemens Networks (NSN) has signed 3G contracts with China Mobile and China Unicom worth a combined 7.6 billion yuan ($1.1 billion).
The deals were part of a $10 billion package of contracts signed in Germany yesterday as part of a high-profile Chinese buying spree in the EU.
Under the frame agreements, NSN will supply W-CDMA networks to China Unicom in 11 provinces and TD-SCDMA and GSM equipment to China Mobile.
"We have always played a key role in the development of China's telecom sector," said NSN's China chief, Zhang Zhiqiang. He NSN had invested in six LTE R&D sites in China in preparation for 4G technology.
Delegates from more than 200 Chinese companies are currently touring the EU negotiating business deals.
