Heads of both Siemens AG from Germany and the U.S.-based Motorola's Tianjin operation have had their confidence strengthened about the companies' future development in China, after the nation's annual central economic conference concluded Monday in Beijing.

Ruey-Bin Kao, chairman of Motorola (China) Electronics Ltd. based in Tianjin, a leading manufacturing base in northern China, told Xinhua Wednesday that the ongoing global economic downturn would not negatively affect his company's business in China. Twenty-two years of experience in the country ensures the company's confidence in the Chinese market.

"In the worldwide recession, China has been an anchor for the global economy by carrying out policy measures quickly and by making massive investments in sustainable infrastructure," said Peter Loscher, president and CEO of Siemens AG.

It would continue to be tough for the global economy in 2010, but China would be one of the economic engines worldwide, he said in Beijing Wednesday.

To prove his confidence, Siemens Ltd., China signed a series of new orders and cooperation agreements, which worth approximately 2 billion yuan (293.3 million U.S. dollars) in total, with Chinese partners over the past few days. Most of the orders and accords cover products from Siemens' environmental portfolio.

According to policy makers who attended the central economic conference, which set the tune for China's economic and social development next year, pointed out that to speed up transformation of the nation's economic growth mode would be a priority for the coming year.

They said it was imperial to integrate the promotion of independent innovation with cultivation of strategic, emerging industries.

Loscher predicted that by 2013, China would become an enormous market for green technologies, which would be valued at 1 trillion U.S. dollars.
