Chinese Vice Premier Zhang Dejiang said Saturday China continues as always to welcome foreign investment and is working to build a fair and stable market.

"China will stick to the opening-up policy and try to improve its investment environment. China sincerely welcomes multinational corporations' expansion of their investments in China," Zhang said at the opening of the 4th International CEO Roundtable of Chinese and Foreign Multinational Corporations in Beijing.

China has introduced capital, technology, talent and management expertise from foreign nations with great sincerity and responsibility since the government adopted its opening-up policy, Zhang said.

Zhang pledged China will continue to improve laws and policies for foreign businesses to ensure an open and transparent legal environment.

Zhang also said China will encourage Chinese enterprises to "go abroad" and participate in international trade and economic cooperation.
