As at the date of this announcement, CDC and its subsidiaries hold             
approximately 36.07% of the shares in the Company and Datang Overseas          
Investment is a wholly-owned subsidiary of CDC. Accordingly, Datang Overseas   
Investment is a connected person of the Company under Chapter 14A of the       
Listing Rules and the Guarantee and Counter Guarantee constitute connected     
transactions of the Company. As each of the applicable percentage ratios (as   
defined under Rule 14.07 of the Listing Rules) in respect of the Guarantee and 
Counter Guarantee is higher than 0.1% and less than 5%, the Guarantee and      
Counter Guarantee are only subject to the reporting and announcement

of the Company under the requirements of Chapter 14A of the Listing Rules.     
                                                                               
Since CDC is the controlling shareholder of the Company, the pledge of the     
358,680,000 H shares of the Company by Datang Overseas Investment to the Bank  
under the Guarantee also triggers disclosure obligation of the Company under   
Rule 13.17 of the Listing Rules and therefore this announcement is also made by
the Company pursuant to Rule 13.17 of the Listing Rules.
