BEIJING -- China expressed dissatisfaction and strong opposition on Sunday to a bill passed by the United States legislature which includes clauses biased against Chinese firms.

The discriminatory clauses concerning China, which are included in the fiscal year 2015 Omnibus Appropriations bill passed by the House of Representatives on Dec 11 (local time), "violate the rule of fair trade and send wrong signals," said Sun Jiwen, spokesman for the Ministry of Commerce.

"China expresses dissatisfaction and strong opposition to this," he added.

According to the bill, the appropriations are banned from being used to import China-made processed poultry products for Chinese meal programs in US schools.

The appropriations are also banned from being used by some US government departments to purchase information technology systems made by Chinese companies, and banned from being used for issuing commercial satellite licenses to China.

"These clauses would not only affect normal business cooperation between companies of the two countries, but also damage the US own interests," Sun said.

"China urges the US to take substantial measures and correct its wrong practices, thus creating a good environment for the healthy development of China-US economic and trade relations," he added.
