As at the date of this announcement, CDC and its subsidiaries hold             
approximately 34.71% 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 the Counter Guarantee Agreement 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 the Counter Guarantee Agreement is higher than 0.1% and less than
5%, the Guarantee and Counter Guarantee are only subject to the reporting and  
announcement requirements but are exempt from the approval by the independent  
shareholders 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  
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.
