Target subscribers:

Institutional investors (and not the general public)

Subject to shareholders' approval, the Chairman (the "Chairman") of the board of directors of the Company (the "Board") or any person authorised by the Chairman will be authorised to determine and finalise the terms and conditions of the Proposed Medium-term Bond Issue and any relevant matters in relation to the same based on the needs of the Company and the market conditions at the time of the issuance, including the determining the time of issue, the issue amount, the issue period and interest rates of the Medium-term Bonds. Further, the Board will be authorised to execute all necessary documents, to conduct appropriate information disclosures and/or to do all such things and acts as are considered necessary or expedient and in the interests of the Company for the purpose of effecting or otherwise in connection with its Proposed Medium-term Bond Issue or any matter incidental thereto.

LETTER FROM THE BOARD

GENERAL INFORMATION

Reference is made to the Notice of the 2007 Annual General Meeting dated 25 March 2008 (the "AGM Notice") and the Supplemental Notice of the 2007 Annual General Meeting dated 9 April 2008 (the "Supplemental AGM Notice") which set out the resolutions to be considered by the Shareholders at the Annual General Meeting (the "AGM") to be held at the Conference Room, No. 62 North Xizhimen Street, Haidian District, Beijing, the People's Republic of China at 9:00 a.m. on Friday, 9 May 2008.

At the AGM which will be held as originally scheduled, approval of the Shareholders will be sought to the issue of the Medium-term Bonds by the Company in the PRC. The relevant resolution is set out as Special Resolution No.14 in the Second Supplemental Notice of the 2007 Annual General Meeting and was submitted to the Company by Aluminum Corporation of China, the controlling shareholder of the Company holding directly approximately 38.56% of the total issued share capital of the Company, pursuant to Article 67 of the Articles of Association of the Company and in compliance with applicable laws.

The directors of the Company consider that the Proposed Medium-term Bond Issue is in the interests of the Company and the Shareholders as a whole and accordingly recommend that all Shareholders vote in favour of Special Resolution No.14 to be proposed at the forthcoming AGM.

SECOND REVISED PROXY FORM

Since the revised proxy form (the "Revised Proxy Form") sent together with the circular of the Company dated 9 April 2008 does not contain the proposed resolution for the Proposed Medium-term Bond Issue as set out in this circular, a new proxy form (the "Second Revised Proxy Form") has been prepared and is enclosed with this circular.

You are requested to complete and return the Second Revised Proxy Form in accordance with the instructions printed thereon to the Company's registrar (with address shown on the cover page of this circular) as soon as possible and in any event no more than 24 hours prior to the time appointed for the holding of the AGM, i.e. 9:00 a.m. on Thursday, 8 May 2008 (the "Closing Time"). Shareholders who have appointed or intend to appoint proxies to attend the AGM are requested to pay particular attention to the special arrangements set out therein.

If you are a non-registered Shareholder (i.e. your Shares are held in an intermediary (for example, a bank, a custodian or a securities broker) or registered in the name of your nominee), you will not receive the Second Revised Proxy Form. You have to give instruction to your intermediary/nominee to vote on your behalf, or if you wish to attend and vote at the AGM, you should arrange with your intermediary/nominee directly to obtain an authorisation.

A Shareholder who has not yet lodged the Revised Proxy Form with the Company's registrar is requested to lodge the Second Revised Proxy Form if he or she wishes to appoint proxies to attend the AGM on his or her behalf. In this case, the Revised Proxy Form should not be lodged with the Company's registrar.

- 3 -

LETTER FROM THE BOARD

A Shareholder who has already lodged the Revised Proxy Form with the Company's registrar should note that:

(i)

If no Second Revised Proxy Form is lodged with the Company's registrar, the Revised Proxy Form will be treated as a valid proxy form lodged by him or her if it is correctly completed. The proxy appointed by the Shareholder will be entitled to vote at his or her discretion or to abstain on any resolution properly put to the AGM other than those referred to in the notice convening the AGM and the Revised Proxy Form, including a resolution for the Proposed Medium-term Bond Issue set out in this circular.

(ii)

If the Second Revised Proxy Form is lodged with the Company's registrar prior to the Closing Time, the Second Revised Proxy Form will revoke and supersede the Revised Proxy Form previously lodged by him or her. The Second Revised Proxy Form will be treated as a valid proxy form lodged by the Shareholder if correctly completed.

(iii)

If the Second Revised Proxy Form is lodged with the Company's registrar after the Closing Time, the Second Revised Proxy Form will be invalid. However, it will revoke the Revised Proxy Form previously lodged by the Shareholder, and any vote that may be cast by the purported proxy (whether appointed under the Revised Proxy Form or the Second Revised Proxy Form) will not be counted in any poll which may be taken on a proposed resolution. Accordingly, Shareholders are advised not to lodge the Second Revised Proxy Form after the Closing Time. If such Shareholders wish to vote at the AGM, they will have to attend in person and vote at the AGM themselves.

Shareholders are reminded that completion and delivery of the Revised Proxy Form and/or the Second Revised Proxy Form will not preclude Shareholders from attending and voting in person at the AGM or at any adjourned meeting should they so wish.

Important:

The revised form of proxy dispatch together with the circular of the Company dated 9 April 2008 are superseded by the second revised form of proxy enclosed herewith.

LETTER FROM THE BOARD

PROCEDURE TO DEMAND A POLL AT THE AGM
