In recent years, China Unicom, as one of the three major telecommunications operators in China, has been seeking ways to expand its market share and enhance its competitiveness. In this process, Unicom has carried out a series of acquisitions and mergers. Among them, the most noteworthy is Unicom's acquisition of another telecommunications operator.

So, which operator did Unicom acquire? The answer is: In 2008, China Unicom successfully acquired 100% of the equity of China Netcom (Group) Corporation Limited (hereinafter referred to as "China Netcom"). This acquisition is regarded as a major consolidation in China's telecommunications industry and an important milestone in the development history of China Unicom.

China Netcom was the second-largest fixed-line operator in China, with a huge subscriber base for both fixed-line phones and broadband services. Through the acquisition of China Netcom, Unicom was able to further expand its fixed-line business scale and enhance its competitiveness in the broadband and fixed-line phone markets. At the same time, this acquisition helped Unicom achieve the integration of fixed-line and mobile networks, providing users with more comprehensive and convenient communication services.

After the acquisition, Unicom integrated its operations and shared resources with China Netcom, further improving overall operational efficiency and service quality. Today, Unicom has become an important force in China's telecommunications market, offering a wide range of communication products and services to its vast customer base.
