Wen was also asked to comment on that some foreign enterprises complained Chinese investment environment not as friendly as before, after Google's claim to pull out from the Chinese market and the arrest of Rio Tinto's four employees on charges of stealing state secrets.

He said the complaint are not in accordance with the fact that there is big amount of foreign capital entering China every year, however, he was still willing to answer the question.

Wen said that China welcomed foreign investors to do their business in line with the Chinese laws. He also encouraged them to bring more research and development centers into the country so as to improve the efficiency in the use of foreign capitals.

China will make institutional arrangements to turn the country into a "fair playing ground" for foreign investors and grant foreign enterprises "national treatment," said Wen.

"Speaking of shortcomings in our work, my contacts with foreign investors are not close enough," said Wen.

He pledged to create more opportunities to exchange ideas with foreign investors in the remaining three years of his tenure.
