The Chinese government will continue to stick to the mutually beneficial opening-up policy and ensure fair competition for foreign-funded firms' investments in China, said Jiang Yaoping, vice minister of the MOC.

China has opened its green economy to competitive bidding processes, said Jiang, adding that bidding processes will be fair and transparent.

"All firms will be treated equally and fairly," he said.

Jiang made the remarks at a press conference concerning the International High-tech Exhibition of Green Industries and Green Economy, which will be held in Beijing from Wednesday.

The four-day event has attracted 127 participants, 85 of which are foreign-funded firms.
