BEIJING, Sept. 20 (Xinhua) -- China is evaluating the impact of the United States' decision to impose additional tariffs on 200 billion U.S. dollars worth of Chinese products, the Ministry of Commerce (MOC) said on Thursday.

"As we can see so far, the products involve six categories, including electromechanical, light industry, textiles and garments, resources and chemical products, agricultural products and pharmaceutical products, and foreign enterprises are likely to account for almost half of the affected enterprises," MOC spokesman Gao Feng told a news conference.

The unilateral trade protectionist measures of the U.S. hurt not only the interests of enterprises and consumers of both China and the U.S. but also the security of the global industrial chain and supply chain, said Gao.

Gao said China is currently working on targeted measures and will release and implement the measures at an appropriate time to help Chinese and foreign enterprises in China cope with possible difficulties and challenges.

In response to questions that some exporters have shifted focus into the domestic market, Gao said some foreign trade enterprises, including foreign-funded enterprise, had explored the domestic market in China due to its size and high consumption potential.
