Aluminum Corporation of China Limited*
(a joint stock limited company incorporated in the People's Republic of China with limited liability)

(Stock Code: 2600)

Reference is made to the announcement of the Company dated 27 October 2009 and the circular of the Company dated 13 November 2009 in relation to, among other things, the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement entered into between the Company and Xinan Aluminum.

Xinan Aluminum itself was formerly a connected person of the Company by reason of its being a 40% shareholder in Chalco SW Aluminum, a subsidiary of the Company. Upon Chinalco's further share acquisition resulting in its holding an aggregate of 49.96% interest in Xinan Aluminum in December 2011, Xinan Aluminum became an associate of Chinalco and at the same time, Chalco SW Aluminium became a connected subsidiary of the Company by reason of the 40% interest held by of Xinan Aluminum (which in turn is owned as to 49.96% by Chinalco) in Chalco SW Aluminum. Transactions between the Company (and its subsidiary, Chalco Southwest Aluminum Cold Rolling) with Chalco SW Aluminum and Xinan Aluminum under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement constitute continuing connected transactions of the Company and Chinalco under Chapter 14A of the Hong Kong Listing Rules.

Upon the official commencement of commercial production of Chalco Southwest Aluminum Cold Rolling, a subsidiary of the Company, the transactions between the Company (including Chalco Southwest Aluminum Cold Rolling) and Chalco SW Aluminum are expected to increase. The Board estimates that the annual cap of the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement for the year of 2012 will no longer meet the needs of the Company's production and operation, and therefore proposes to revise the annual cap of the expenditure transactions for the year ending 31 December 2012.

As the highest percentage ratio applicable to the proposed revised annual cap for the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement for the year ending 31 December 2012 exceeds 5%, the Proposed Revision of Annual Cap is subject to the reporting, announcement, Independent Shareholders' approval and annual review requirements under Chapter 14A of the Hong Kong Listing Rules.

A circular containing, among others, (i) details of the Proposed Revision of Annual Cap; (ii) a letter from China Merchants Securities to the Independent Board Committee and the Independent Shareholders in respect of the Proposed Revision of Annual Cap; and (iii) a letter from the Independent Board Committee to the Independent Shareholders in respect of the Proposed Revision of Annual Cap will be despatched to the Shareholders pursuant to the Hong Kong Listing Rules on or before 15 May 2012.

INTRODUCTION

Reference is made to the announcement of the Company dated 27 October 2009 and the circular of the Company dated 13 November 2009 in relation to, among other things, the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement entered into between the Company and Xinan Aluminum.

Xinan Aluminum itself was formerly a connected person of the Company by reason of its being a 40% shareholder in Chalco SW Aluminum, a subsidiary of the Company. Upon Chinalco's further share acquisition resulting in its holding an aggregate of 49.96% interest in Xinan Aluminum in December 2011, Xinan Aluminum became an associate of Chinalco and at the same time, Chalco SW Aluminium became a connected subsidiary of the Company by reason of the 40% interest held by Xinan Aluminum (which in turn is owned as to 49.96% by Chinalco) in Chalco SW Aluminum. Transactions between the Company (and its subsidiary, Chalco Southwest Aluminum Cold Rolling) with Chalco SW Aluminum and Xinan Aluminum under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement constitute continuing connected transactions of the Company and Chinalco under Chapter 14A of the Hong Kong Listing Rules.

Upon the official commencement of commercial production of Chalco Southwest Aluminum Cold Rolling, a subsidiary of the Company, the transactions between the Company (including Chalco Southwest Aluminum Cold Rolling) and Chalco SW Aluminum are expected to increase. The Board estimates that the annual cap of the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement for the year of 2012 will no longer meet the needs of the Company's production and operation, and therefore proposes to revise the annual cap of the expenditure transactions for the year ending 31 December 2012.

TERMS OF SUPPLY OF ALUMINUM, ALUMINUM ALLOY INGOTS AND ALUMINUM FABRICATION SERVICES

The Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement dated 20 October 2008 (and renewed on 31 December 2009) was entered into between the Company and Xinan Aluminum for the supply of aluminum, aluminum ingots and aluminum fabrication services. The agreement was for a term of three years expiring on 31 December 2012. Transactions under the agreement are to be paid by cash upon delivery. The scope of the transactions under the agreement includes the following:

Chalco Southwest Aluminum Cold Rolling commenced official production in June 2011. Prior to Xinan Aluminum becoming an associate of Chinalco, the transactions between Chalco SW Aluminum and Chalco Southwest Aluminum Cold Rolling were intra-group transactions of the Company and were not connected transactions under the Hong Kong Listing Rules. Upon Xinan Aluminum becoming an associate of Chinalco, all transactions between Chalco Southwest Aluminum Cold Rolling with Chalco SW Aluminum and Xinan Aluminum will be treated as connected transactions under the Hong Kong Listing Rules. The above expenditure transactions for the year ended 31 December 2011 did not reflect the transactions between Chalco Southwest Aluminum Cold Rolling with Chalco SW Aluminum and Xinan Aluminum.

Proposed Revision of the 2012 Annual Cap

Upon Chalco SW Aluminium becoming a connected subsidiary of the Company and upon the official commencement of commercial production of Chalco Southwest Aluminum Cold Rolling in June 2011, the Board estimates that the annual cap of the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement for the year of 2012 will no longer meet the needs of the Company's production and operation, and therefore proposes to revise the annual cap of the expenditure transactions for the year ending 31 December 2012.

The existing and revised annual caps for the transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement for the year ending 31 December 2012 are set out as follows:

As at the date of this announcement, the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement have not exceeded the annual cap for the year ending 31 December 2012.

III

REASONS FOR REVISION OF THE 2012 ANNUAL CAP FOR THE EXPENDITURE TRANSACTIONS UNDER THE PROVISION OF ALUMINUM AND ALUMINUM ALLOY INGOTS AND ALUMINUM FABRICATION SERVICES AGREEMENT

The Company expects an increase in the 2012 annual cap for the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement mainly due to the following reasons:

(1)

Chalco Southwest Aluminum Cold Rolling, a subsidiary of the Company, officially commenced production in June 2011. For the purposes of its production, it purchases hot-rolled blanks from Chalco SW Aluminum. It is estimated that its transactions with Xinan Aluminum and Chalco SW Aluminum will substantially increase upon the commencement of commercial production. It is estimated that its transaction amount with Chalco SW Aluminum will substantially increase from approximately RMB1,278 million in year 2011 to approximately RMB3,643 million for year 2012; and

(2)

Upon Chinalco's further share acquisition resulting in its holding an aggregate of 49.96% interest in Xinan Aluminum, both Xinan Aluminum and Chalco SW Aluminum became connected persons of the Company and consequently, the transaction amounts which have to be accounted for as connected transactions between the Company (including Chalco Southwest Aluminum Cold Rolling) and Xinan Aluminum will also increase.

IV

HONG KONG LISTING RULES IMPLICATIONS

Chinalco is the controlling shareholder and a connected person of the Company. Xinan Aluminum is an associate of Chinalco, and therefore also a connected person of the Company under the Hong Kong Listing Rules. By virtue of Chinalco's interest in Chalco SW Aluminum through Xinan Aluminum, Chalco SW Aluminum is also a connected subsidiary of the Company. Therefore, the transactions between the Company (including Chalco Southwest Aluminum Cold Rolling) with Xinan Aluminum and Chalco SW Aluminum under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement constitute continuing connected transactions of the Company under Chapter 14A of the Hong Kong Listing Rules.

As the highest percentage ratio applicable to the proposed revised annual cap for the expenditure transactions under the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement for the year ending 31 December 2012 exceeds 5%, the Proposed Revision of Annual Cap is subject to the reporting, announcement, Independent Shareholders' approval and annual review requirements under Chapter 14A of the Hong Kong Listing Rules.

As Mr. Xiong Weiping, the Chairman of the Board and Mr. Lv Youqing, a non-executive Director also hold management positions in Chinalco, the controlling shareholder of the Company, they have abstained from voting on the board resolution in respect of the Proposed Revision of Annual Cap. Save as the aforementioned, none of the Directors has material interest in the transactions and therefore no other Director has abstained from voting on such board resolution.

V

REASONS FOR ENTERING INTO THE PROVISION OF ALUMINUM AND ALUMINUM ALLOY INGOTS AND ALUMINUM FABRICATION SERVICES AGREEMENT

Due to the long-term relationship between the Group and Xinan Aluminum, the Company considers that it is beneficial to enter into the continuing connected transactions as these transactions have facilitated and will continue to facilitate the operation and growth of the Group's business. The Board (including independent non-executive Directors) considers that the Provision of Aluminum and Aluminum Alloy Ingots and Aluminum Fabrication Services Agreement and the transactions thereunder are entered into (i) in the ordinary and usual course of business of the Group; (ii) on normal commercial terms; and (iii) on terms that are fair and reasonable and in the interests of the Company and its Shareholders as a whole.
