Since the Board has considered and approved the provision of entrusted loan

such loan will be provided in stages according to the construction progress,   
the Company entered into the Entrusted Loan Agreement with ICBC Xuanwu Branch

provision of the Entrusted Loan of a principal amount of RMB200 million by the

REASONS FOR AND BENEFITS OF ENTERING INTO THE ENTRUSTED LOAN AGREEMENT

In order to ensure the smooth progress of the Duolun Coal Chemical Project, the
Company intends to provide the entrusted loan facility of no more than RMB500
million to Duolun Coal Chemical Company according to the construction progress
of the Duolun Coal Chemical Project and such loan will be provided in stages
according to construction progress. The Company is of the view that the
provision of the Entrusted Loan to Duolun Coal Chemical Company is beneficial
for the support of the smooth construction of the Duolun Coal Chemical Project.

The Directors (including the independent non-executive Directors) are of the
view that the terms of the Entrusted Loan Agreement are fair and reasonable,
have been negotiated on an arm's length basis between all parties thereto and
determined on normal commercial terms, and are in the interests of the Company

CONNECTED TRANSACTION

As at the date of this announcement, Duolun Coal Chemical Company is owned as
to 60% and 40% by the Company's wholly-owned subsidiary - Energy and Chemical
Company and CDC, respectively. CDC is the controlling Shareholder of the
Company which together with its subsidiaries collectively hold approximately
36.07% of the issued share capital of the Company. Duolun Coal Chemical Company
is therefore a connected person of the Company and the Entrusted Loan Agreement
constitutes a connected transaction of the Company under Chapter 14A of the
Listing Rules.

As each of the applicable percentage ratios (as defined in Rule 14.07 of the
Listing Rules) in respect of the Entrusted Loan Agreement is more than 0.1%
but less than 5% and the Entrusted Loan Arrangement is entered into on normal
commercial terms, the Entrusted Loan Agreement is only subject to the reporting
and announcement requirements but is exempt from the requirement of approval by
the Independent Shareholders under Chapter 14A of the Listing Rules.

Those Directors who have a material interest in the transaction under the
Entrusted Loan Agreement (by virtue of being the principal management staff of
CDC), i.e., Mr. Liu Shunda, Mr. Hu Shengmu and Mr. Fang Qinghai, have abstained
from voting at the relevant Board meeting for approval of the Entrusted Loan
Agreement.
