                             Networks

BEIJING, May 2, 2012 (GLOBE NEWSWIRE) -- ChinaCache International
Holdings Ltd. ("ChinaCache" or the "Company") (Nasdaq:CCIH), a leading
total solutions provider of internet content and application delivery
services in China, today announced that it has established the Content
Aware & Intelligent Services Lab ("CAIS" or the "Lab") jointly with
Beijing University of Posts and Telecommunications ("BUPT"), one of
China's most renowned universities in the field of telecommunications.

The Lab aims to leverage ChinaCache's rich experience in CDN technology
and BUPT's strong research capabilities to provide total solutions to
the next generation of internet networks. According to the MIIT, which
is responsible for the regulation and development of China's internet
among other things, the Chinese government's "Broadband China" strategy
calls for improving China's internet bandwidth speed to 20 Mbps for
urban households by the end of 2015. This government initiative, states
Dr. Ken Zhang, ChinaCache's CTO, "will provide an opportunity for the
Lab to address a national need while also providing a unique market
opportunity."

ChinaCache and BUPT will collaborate to conduct research involving
content awareness, intelligent services, and other key technologies to
enable the next generation of networks, which is expected to use IPv6
protocols. According to Dr. Zhang, ChinaCache's Index will be a
significant asset in developing content-aware technologies because the
Lab will be able to use the rich and abundant internet data that pass
through ChinaCache's network and are stored in the Index, "Ultimately,
the Lab aims to develop solutions that will accelerate internet data
delivery speeds while utilizing content-aware networks," commented Dr.
Zhang. "We believe this research will lead to enhanced internet
services and improved user experiences."

The first research project will focus on developing a client-based
system of internet awareness and network acceleration to increase data
delivery speeds over the internet. This technology can be applied in
personal computers, mobile devices, IPTV, and other terminals.

"ChinaCache is excited to establish a partnership with such a
prestigious university. Its academic and research leadership, together
with its commitment to excellence, will help ensure the future success
of CAIS," commented Mr. Song Wang, the founder, chairman and CEO of
ChinaCache. "The Lab's establishment comes at an opportune time and
coincides with China's broadband initiative, which seeks to accomplish
what ChinaCache does best: improve network speeds."
