国内英语新闻:Premier Wen refutes allegation Chinese investment environment worsening

Wen said China welcomes companies which meet China industry policies to invest in China, adding that the government will ensure such companies having access to the Chinese market.

"For those which have entered China, they all enjoy national treatment as Chinese companies do, no matter whether they are a foreign-funded company, a joint venture or a joint stock company, " Wen said.

Wen also promised China would never block the export of rare earth minerals to foreign countries, but said minerals should be exported at a reasonable price and volume. China supplies about 90 percent of the world's rare earth minerals.

The trade seminar came after China and Germany Friday signed ten deals in Beijing involving green energy, culture and a joint venture producing trucks.

The two sides also signed a joint declaration on the establishment of an environmental partnership that will involve water resource protection, equipment safety and evaluation, energy conservation, renewable energy and technology.

"China-Germany cooperation is at a new starting point," Wen said.

After the seminar, Wen and Merkel visited China-German joint venture Siemens Signaling Company Ltd.

Merkel started a four-day visit to China on Thursday, her fourth trip to China since taking office as German Chancellor in 2005.
