--------------------------------------------------------------------------------
   The board of directors of the Company announces that on 15 September 2005,
   CNC China, a wholly-owned subsidiary of the Company, entered into the
   Cooperation Agreement with China Netcom Group. Pursuant to the Cooperation
   Agreement, CNC China agreed to provide telecommunications goods and
   services to BOCOG for the 2008 Beijing Olympic Games before 31 December
   2008. As consideration, CNC China is entitled to the right and opportunity
   to conduct products-related marketing activities by using the 2008 Olympics
   composite logo and sponsorship logo as provided for under the Sponsorship
   Agreement. Based on a comprehensive estimation, the aggregate value of the
   telecommunications goods and services to be provided by CNC China under the
   Cooperation Agreement shall not exceed the consideration of the Cooperation
   Agreement, which is RMB480 million, being the estimated value of such right
   and opportunity.

   Since China Netcom Group is the ultimate controlling shareholder of the
   Company, beneficially owning approximately 70.49% interest in the Company,
   it is a connected person of the Company. The Cooperation Agreement
   constitutes a connected transaction of the Company under the Listing Rules.
   As each of the percentage ratios is less than the 2.5% threshold under Rule
   14A.34 of the Listing Rules, the Cooperation Agreement is exempt from the
   independent shareholders' approval requirements under Rule 14A.32 of the
   Listing Rules, but such connected transaction will still be subject to the
   reporting and announcement requirements set out in Rules 14A.45 to 14A.47
   of the Listing Rules. Details of the Cooperation Agreement will be included
   in the Company's next published annual report.

BACKGROUND

China Network Communications Group Corporation ("China Netcom Group"), the
Company's ultimate controlling shareholder, entered into an agreement (the
"Sponsorship Agreement") with Beijing Organization Committee for the Games of
the XXIX Olympiad ("BOCOG"), which agreement designated China Netcom Group as
the exclusive fixed-line telecommunications services partner in the People's
Republic of China ("PRC") for the 2008 Beijing Olympic Games.

As a partner, China Netcom Group is required to provide cash and goods and
services to support the 2008 Beijing Olympic Games. As mentioned in the
prospectus of the Company dated 4 November 2004, the Company will sponsor a
portion of such support. In return, BOCOG will grant China Netcom Group and
certain affiliates of China Netcom Group the right to, among other things,
conduct promotion activities by using certain 2008 Olympics logos.

As the dominant provider of fixed-line telecommunications services in Beijing,
the principal venue of the 2008 Beijing Olympic Games, China Netcom (Group)
Company Limited ("CNC China"), a wholly-owned subsidiary of the Company, will
sponsor a portion of the required support under the Sponsorship Agreement
through providing telecommunications goods and services to BOCOG under the
terms and conditions of a cooperation agreement with China Netcom Group dated
15 September 2005 (the "Cooperation Agreement").

COOPERATION AGREEMENT

Date:                            15 September 2005
Parties:                         (i)   CNC China; and
                                 (ii)  China Netcom Group

Pursuant to the Cooperation Agreement, CNC China agreed to provide
telecommunications goods and services to BOCOG for the 2008 Beijing Olympic
Games before 31 December 2008.

The monetary value of the telecommunications goods and services to be provided
by CNC China to BOCOG under the Cooperation Agreement shall be calculated on
the basis of the most favourable prices offered by CNC China to its customers
for the relevant goods and services.

The telecommunications goods and services to be provided by CNC China under
the Cooperation Agreement shall constitute a portion of the required support
to be provided by China Netcom Group to BOCOG in relation to the 2008 Beijing
Olympic Games under the Sponsorship Agreement.

In consideration for the provision of telecommunications goods and services by
CNC China to BOCOG for the 2008 Beijing Olympic Games under the Cooperation
Agreement, CNC China is entitled to the right and opportunity to conduct
products-related marketing activities by using the 2008 Olympics composite
logo and sponsorship logo as provided for under the Sponsorship Agreement.
Based on a comprehensive estimation, the aggregate value of the
telecommunications goods and services to be provided by CNC China under the
Cooperation Agreement shall not exceed the consideration of the Cooperation
Agreement, which is RMB480 million, being the estimated value of such right
and opportunity.

REASONS FOR AND BENEFITS OF ENTERING INTO THE COOPERATION AGREEMENT

The Company is a leading fixed-line telecommunications operator in the PRC and
a leading international data communications operator in the Asia-Pacific
region. With CNC China entering into the Cooperation Agreement with China
Netcom Group, the Company and its subsidiaries (together the "Group") will be
able to associate itself with China Netcom Group's sponsorship of the 2008
Beijing Olympic Games. The Olympic Games, being one of the most important
international events, attracts attention from all over the world. The Company
believes that through China Netcom Group becoming the exclusive fixed-line
telecommunications services partner in the 2008 Beijing Olympic Games and the
Group's ability to associate itself with the efforts of China Netcom Group,
the Group will consolidate its market leading position in its existing service
regions in the PRC, in particular, Beijing Municipality. The Company will also
be able to enhance the recognition of the Company in countries and regions
outside its existing service regions in and outside of the PRC. The Company
considers this to be an unique marketing opportunity.

The directors (including the independent non-executive directors) of the
Company consider that the terms of and the arrangements under the Cooperation
Agreement are fair and reasonable and in the interests of the Company and its
shareholders as a whole.

RELATIONSHIP WITH CHINA NETCOM GROUP

China Netcom Group is a state-owned enterprise established under the laws of
the PRC and is the ultimate holding company of the Company. As at the date of
this announcement, China Netcom Group beneficially owns approximately 70.49%
of the Company's issued share capital through China Netcom Group Corporation
(BVI) Limited.

China Netcom Group is the second largest fixed-line telecommunications
operator in the PRC. China Netcom Group owns and operates its fixed-line
telecommunications networks, and provides telecommunications services
including fixed-line telecommunications, broadband and other Internet-related
services in all provinces, municipalities and autonomous regions in the PRC
that are outside the Company's existing northern and southern service regions
(which include Beijing Municipality, Tianjin Municipality, Hebei Province,
Henan Province, Shandong Province, Liaoning Province, Shanghai Municipality
and Guangdong Province).

LISTING RULES IMPLICATION

Since China Netcom Group is the ultimate controlling shareholder of the
Company, beneficially owning approximately 70.49% interest in the Company, it
is a connected person of the Company. The Cooperation Agreement constitutes a
connected transaction of the Company under the Rules Governing the Listing of
Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules").
As each of the percentage ratios is less than the 2.5% threshold under Rule
14A.34 of the Listing Rules, the Cooperation Agreement is exempt from the
independent shareholders' approval requirements under Rule 14A.32 of the
Listing Rules, but such connected transaction will still be subject to the
reporting and announcement requirements set out in Rules 14A.45 to 14A.47 of
the Listing Rules. Details of the Cooperation Agreement will be included in
the Company's next published annual report.
