We
established an overall marketing framework
and increased our market shares. We coordinated
the common market of CSEC and non-listed entities
within Shenhua. We gave more priority to our
key customers by ensuring coal quality, service
and full implementation of contracts. We supervised
the loading process to keep the reputation
of “Shenhua Coal Brand”. We overperformed
in the purchase of external coal and coal
blending. Efforts have also been made to the
promotion of the coal products of non-listed
entities with Shenhua. We sold brow coal of
Shenhua Baorixile Energy Company to Huaneng
Yinkou and Guohua Suizhong power plants, coordinated
coal export and coal payment back of Shenhua
Xinjiang Coal Company, helped Shenhua Ningxia
Coal (Group) Industry Corporation with its
external coal sales and transportation, and
developed market in eastern and northern China
for “Western Five” Coal Company’s high calorific
and high sulfur fat coal.
