China Unicom ups 4G ante

China United Network Communications Group Co Ltd said on Tuesday it will spare no efforts to offer better 4G services and products, as the carrier is struggling to catch up with market leader China Mobile Co Ltd.

Wang Xiaochu, chairman of China Unicom, said: "We will channel all of our core resources to ensure a better 4G network, faster Internet speed and better-quality voice calls."

In his first public speech after taking the helm of the country's second-largest telecom carrier in August, Wang said he was determined to upgrade China Unicom's 4G service and products. "This will be our top priority and the most important strategy," Wang added.
