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

(Stock Code: 2600)

Upon appraisal by an independent valuer of the prevailing market rental of the land use rights of the land leased by Chinalco to the Company, the total annual rental of the land use rights of the land leased by Chinalco to the Company will be adjusted to RMB620 million commencing from 1 January 2007. The appraisal of the prevailing market rent was made pursuant to a provision for rental adjustment in the Land Use Right Leasing Agreement.

The revised annual rental of RMB620 million is greater than 0.5% but does not exceed 5% of the applicable percentage ratio under the Listing Rules of the Shanghai Stock Exchange and is less than 2.5% of the applicable percentage ratio under the Listing Rules. The rental revision is required to be disclosed by way of announcement but is not required to be approved by the independent shareholders of the Company. Upon the revision of the annual rental to RMB620 million as provided by the provision for rental adjustment in the Land Use Right Leasing Agreement and the publication of this announcement, the annual cap of this exempt continuing connected transaction will be revised from RMB400 million to RMB620 million for each of the three financial years ending 31 December 2009.

The board of directors of Aluminum Corporation of China Limited (the directors, "Directors", the board, "Board" and the company, "Company") wishes to announce that upon appraisal by an independent valuer (a corporation licensed to carry out securities related services in the People's Republic of China) of the prevailing market rental of the land use rights of the land leased by Aluminum Corporation of China ("Chinalco") to the Company, the total annual rental of the land use rights of the land leased by Chinalco to the Company will be adjusted to RMB620 million commencing from 1 January 2007. The appraisal of the prevailing market rent was made pursuant to a provision for rental adjustment in the Land Use Right Leasing Agreement entered into between the Company and Chinalco on 5 November 2001 (the "Land Use Right Leasing Agreement").

In 2001 and as part of the reorganization of the Company in preparation for the Company's listings, the Company entered into the Land Use Right Leasing Agreement with Chinalco for the leasing of 453 pieces of land in the People's Republic of China ("PRC") covering an aggregate area of approximately 58.3 million square meters for the purpose of all the operations and businesses of the Company and its subsidiaries. The initial annual rent was fixed at RMB134.3 million. Under the Land Use Right Leasing Agreement, the leased term for each piece of allocated land is 50 years commencing from 1 July 2001 and the leased term for each piece of granted land is until the expiry of the relevant land use right permit.

Pursuant to the Land Use Right Leasing Agreement, the annual rent shall be reviewed every three years at a rent not higher than the prevailing market rent as confirmed by an independent valuer. Such rental adjustment shall reflect the market conditions prevalent at time of such adjustment, including current market prices, inflation or deflation, as appropriate, and such other pertinent factors as may be reasonably considered during such negotiations. It is further provided that if there is any adjustment to the land taxes, adjustment to the rent may be made after negotiations and agreement between Chinalco and the Company.

Since 2001, due to the increase in land taxes, the annual rental has been adjusted three times to take into account the increases in land taxes and other governmental payments, from RMB134.3 million in 2001 to RMB168 million in 2003, RMB225 million in 2004 and RMB270 million in 2006. However, no rental review pursuant to the Land Use Right Leasing Agreement has been conducted and no rental increase based on the prevailing market rent has been made since 2001.

Based on an appraisal report dated 30 April 2007 prepared by China Enterprise Appraisal Company Limited, an independent valuer qualified in the PRC, the market rental of the land use rights leased by Chinalco to the Company as at 1 January 2007 was assessed at RMB619.2 million in accordance with the methods for determining land rental as provided in the relevant PRC laws and regulations. The appraisal has taken into account the prevailing market conditions as well as changes in the number of the pieces of land leased by Chinalco to the Company. A summary of the land use rights leased by Chinalco to the Company is as follows:

1.

Total pieces of land: 455 pieces

2.

Total area: 59.64 million square meters, an increase of 1.3 million square meters as compared to 2001

3(i)

Total pieces of allocated land: 439 with a total area of approximately 59.27 million square meters

3(ii)

Total pieces of granted land: 16 with a total area of approximately of 0.37 million square meters

4.

Prevailing market rent: RMB620 million for 2007

The rental of the land use rights of the land leased by Chinalco to the Company is payable quarterly in arrears. The Company will pay the revised rental to Chinalco starting from 1 September 2007 onwards. The difference between the original amount of rental and the revised rental for the period from 1 January 2007 to 31 August 2007 payable by the Company will be paid by the Company to Chinalco by the end of 2007.

The land use rights of the land leased under the Land Use Right Leasing Agreement are essential to all the operations and business of the Company and its subsidiaries. The Board is of the view that it is in the interest of the Company to maintain the lease of those land use rights for the business operations of the Company.

A supplemental agreement will be entered into between Chinalco and the Company as soon as practicable to amend the schedules to the Land Use Right Leasing Agreement to reflect the changes in the total pieces of land and the area leased to the Company and the annual rent payable. Other than the above amendments, the terms and conditions of the Land Use Right Leasing Agreement dated 5 November 2001 will remain unchanged.

The revised annual rental of RMB620 million is greater than 0.5% but does not exceed 5% of the applicable percentage ratio under the Listing Rules of the Shanghai Stock Exchange and is less than 2.5% of the applicable percentage ratio under the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules"). The rental revision is required to be disclosed by way of announcement but is not required to be approved by the independent shareholders of the Company.

The annual cap for the payment of annual rental under the Land Use Right Leasing Agreement, which is an exempt continuing connected transaction, as determined by the Company in its circular dated 27 December 2006 to its shareholders was RMB400 million for each of three financial years ending 31 December 2009. Upon the revision of the annual rental to RMB620 million as provided by the provision for rental adjustment in the Land Use Right Leasing Agreement and the publication of this announcement, the annual cap of this exempt continuing connected transaction will be revised to RMB620 million for each of the three financial years ending 31 December 2009.

The Company is primarily engaged in the production, sales and research of alumina and primary aluminum through its various branch factories, subsidiaries and associated companies.

Chinalco is a controlling shareholder as well as a connected person (as both terms are defined in the Listing Rules) of the Company. It is a state-owned enterprise incorporated under the laws of the People's Republic of China, whose entities and business were contributed to the Company upon the Company's establishment. The principal activities of Chinalco includes aluminia fabrication, copper fabrication and manufacturing of aluminum.
