CHINA GRENTECH CORPORATION LIMITED (THE "COMPANY")

We have acted as special Cayman legal counsel to the Company in connection with
an initial public offering of certain ordinary shares in the Company (the
"Shares") as described in the prospectus contained in the Company's registration
statement on Form F-1 (the "Registration Statement" which term does not include
any exhibits thereto) to be filed by the Company under the United States
Securities Act of 1933 (the "Securities Act") with the United States Securities
and Exchange Commission (the "Commission") on the date hereof.

For the purposes of giving this opinion, we have examined and relied upon copies
of the following documents:

(i)  the Registration Statement; and

(ii) a draft of the prospectus (the "Prospectus") contained in the Registration
     Statement.

We have also reviewed and relied upon (1) the memorandum of association and the
articles of association of the Company, (2) copies of the minutes of meetings of
and written resolutions passed by directors and shareholders of the Company,
both dated 25 August, 2005 (collectively the "Minutes"), (3) the register of
members of the Company, and (4) such other documents and made such enquiries as
to questions of law as we have deemed necessary in order to render the opinion
set forth below.



                                                                            CD&P

We have assumed (i) the genuineness and authenticity of all signatures, stamps
and seals and the conformity to the originals of all copies of documents
(whether or not certified) examined by us and the authenticity and completeness
of the originals from which such copies were taken; (ii) the accuracy and
completeness of all factual representations made in the Prospectus and
Registration Statement and other documents reviewed by us, (iii) that the
resolutions contained in the Minutes are full and accurate records of
resolutions passed at meetings of the directors and shareholders of the Company
in accordance with the articles of association of the Company; (iv) that there
is no provision of the law of any jurisdiction, other than the Cayman Islands,
which would have any implication in relation to the opinions expressed herein;
(v) the validity and binding effect under the laws of the United States of
America of the Registration Statement and the Prospectus and that the
Registration Statement will be duly filed with or declared effective by the
Commission; and (vi) that the Prospectus, when published, will be in
substantially the same form as that examined by us for purposes of this opinion.

We have made no investigation of and express no opinion in relation to the laws
of any jurisdiction other than the Cayman Islands. This opinion is to be
governed by and construed in accordance with the laws of the Cayman Islands and
is limited to and is given on the basis of the current law and practice in the
Cayman Islands.

On the basis of and subject to the foregoing, we are of the opinion that:

(1)  The Company is duly incorporated and existing under the laws of the Cayman
     Islands.

(2)  The issue of the Shares has been duly authorised, and when the Shares have
     been issued, delivered and paid for in the manner described in and pursuant
     to the terms of the Prospectus and Registration Statement will be validly
     issued, fully paid and non-assessable (meaning that no further sums are
     payable to the Company with respect to the holding of such Shares).

We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement and to the references to us under the
headings "Taxation", "Enforcement of Civil Liabilities" and "Legal Matters" in
the Prospectus contained in the Registration Statement. In giving such consent,
we do not thereby admit that we come within the category of persons whose
consent is required under Section 7 of the Securities Act, or the Rules and
Regulations of the Commission thereunder.



Yours faithfully,


CONYERS DILL & PEARMAN
