CHENGDU, Dec. 24 (Xinhua) -- China is committed to creating a market-oriented, law-based and international business environment, and will treat enterprises of all ownership equally, Chinese Premier Li Keqiang said Tuesday.

Li made the remarks at the opening ceremony of the 7th China-Japan-Republic of Korea (ROK) Business Summit in southwestern city of Chengdu.

China will not adopt protectionism because of trade deficits with the ROK and Japan, Li said, noting that China is unswervingly expanding its opening-up and its door to the outside world will open even wider.

He also welcomed companies of the ROK and Japan to seize the opportunity of China's opening up to take advantage of the growing business opportunities, so as to better achieve mutual benefit and win-win results.
