BEIJING, CHINA: A Chinese worker walks by a giant billboard for Sinopec, China's largest oil refiner and producer of petrochemical products, in Beijing 26 March 2004. Major Japanese chemical maker Mitsui Chemicals and Sinopec said Friday they would jointly produce a high-performance plastic in China, and will build a plant in Shanghai to make the product, bisphenol A, which is used for home electronics and optical discs such as CDs and DVDs.

ST. ALBERT, Alta. - A Chinese engineering firm has pleaded guilty to three workplace safety charges related to a fatal accident in the oilsands five years ago.

Two workers were killed and another four injured when the roof on a large tank collapsed at Canadian Natural Resources Ltd.'s (TSX:CNQ) Horizon project site.

Twenty-one other charges against Chinese contractors on the Horizon project were withdrawn.

Another 29 charges against the Calgary-based company have been stayed, meaning the government has a year to revive them.

Sinopec Shanghai Engineering Canada is to be sentenced on Jan. 24.

The pleas, which were entered Sept. 5, came to light this morning when a trial was to have begun.
