Beijing is planting trees and plants along riverbanks instead of covering them with concrete to fix its river system. It has taken almost 10 years for the capital to accept and use this idea. The ecosystems in the streams are gradually coming back to life because of the cleaner water, providing a good habitat for animals and plants, and ideal leisure sites for local residents.  Zhuanhe which connects with Kun Ming Lake in the Summer Palace is one of successful example of the river ecological treatment in Beijing. "In Beijing, there are 52 rivers with a total length of 520 kilometers inside the sixth ring road. Yongding and Jingmi rivers are the city's two main water sources, and Qinghe, Bahe, Tonghui and Liangshui are key drainage waterways," said Yu Kongjian, dean of the Sight Engineer Institute with Peking University. Originally, Beijing only wanted to control the floods by letting water flow out as soon as possible. Therefore, riverbanks were cemented down in order to prevent water leakage and the growth of plants, which could slow the water speed down. However, the shortage of rainfall in Beijing since 1999 showed that this method was not correct. On the one hand, streams had less fresh water to clean themselves. On the other, more polluted water was dumped into the rivers as more people moved into the capital. And in the summer of 2001, something bad happened. "The rivers in Beijing turned blue overnight and gave off a smelly odor," said Liu Peibin, vice engineer of Beijing Water Authority. There was an algae bloom due to so much pollution in the water. Algae covered the water surface and consumed most of the oxygen, and many creatures in the water died as a result. These "concrete pools" became the haven for swarms of mosquitoes which forced tens of thousands of residents nearby to close their windows and doors tightly especially in summer days. The water authorities had to act quickly for public safety. The first step was to demolish the concrete covering the riverbanks. The soil was exposed to water again, and the water could circulate down to the riverbank. Secondly, in order to stimulate oxygen in the streams, engineers put big stones in the water to create mini waterfalls. And they grew trees like willows and plants such as bulrush along the riverbanks. "Bulrush can purify polluted water through absorbing nitrogen and phosphorus in the water and exhaling oxygen," Deng added. "Gradually Zhuanhe came back to life and got rid of the polluted and smelly water. This would be impossible today if the brook was still covered in concrete." "What we did with Zhuanhe is a milestone in the progress of river treatment with new ecological ideas," said Deng Zhuozhi, vice engineer of Beijing Water Project Institute. He took charge of the Zhuanhe project. "How to fix up rivers depends on our attitude towards floods. We should learn to make friends with floods in a country where two-thirds of China's cities are short of water. Therefore we should reserve water as much as possible instead of discharging it ineffectively," said Yu.

The highly anticipated Beijing-Shanghai high-speed railway will begin construction next month, a Ministry of Railways official said.The ministry source, who did not want to be named, confirmed in a phone interview yesterday that preparations are now being made for a ceremony to commence construction of the system.Based on that timeframe, the railway will be completed by 2013. Trains running on the 1,318 km railway will then be able to travel at speeds of up to 350 kph and will cut travel time between the two cities from the current 10 hours to less than five.The project involves one of the largest amounts of investment on railways. Industry sources say it will cost more than 200 billion yuan ( billion), more than the 180 billion yuan needed for the Three Gorges Project.Officials say the project will also employ a set of locally developed high-speed railway technology for the first time.The country is said to have already mastered the technologies needed to lay high-speed rail tracks and trains.The first homegrown train able to reach 300 kph rolled off the production line over the weekend, marking China's entry into "an elite club that includes Japan, France and Germany to become the fourth country capable of making such trains", Wang Yongping, Ministry of Railways spokesman said.Officials added that the railway still relies on foreign companies, such as the Germany-based Siemens, to build its signal network and other systems.China has been upgrading the scale and speed of its railway network in the past decade, and the 11th Five Year Plan period (2006-10) is regarded as a critical period for building high-speed railways that can travel at speeds of 200 kph as part of an extensive transport network.At least eight express passenger railways were being constructed as of last year.Xinhua contributed to the story

Across the country, something strange is happening. Bookstores are opening for business at 7 o'clock this morning, two hours earlier than usual. The reason: Harry Potter and the Deathly Hallows, the eagerly awaited seventh and final installment, is due out today. And like children around the world, Chinese youngsters can't wait to start reading it, which is certain to make the Harry Potter series the best-selling foreign language books in the country's history. "Never has an English language book attracted such great attention as Harry Potter," said Liang Jianrui, vice-president of the China National Publications Import and Export Corporation, China's largest foreign book trader. The company has imported 50,000 copies of Harry Potter and the Deathly Hallows, or about half of the total imports of the books in China. The figure is in sharp contrast with the company's imports of one of the New York Times bestsellers of about 100 copies. The hardback book, available at retailers, 800 newspaper vendors in Beijing and online book retailers, has US and UK versions. The two versions are slightly different in terms of layout and illustrations, Liang said. The popularity of the Harry Potter books in English has been a result of Chinese people's improved English skills and more frequent cultural exchanges in recent years. "We didn't create the demand," said Liang. "The demand creates this miracle." "All of our stock has been preordered by retailers. The book will hit a record." The UK version is priced at 208 yuan and the US one at 218 yuan (.60), which is lower than 17.99 pounds in the United Kingdom and .99 in the United States. The books arrived in Beijing on July, where they have been stored in boxes reading, "Don't open until July 21". "It is fantastic and exciting to know that Chinese readers are interested in Harry Potter and the Deathly Hallows," said Lucy Holden, head of Children's Publicity at Bloomsbury, the book's British publisher. "There is huge excitement about the book. I hope readers in China will enjoy reading it," she told China Daily in telephone interview.

WASHINGTON - Senior officials from the United States and China are scheduled to hold a twice-yearly dialogue in Washington this week on bilateral and multilateral issues, AFP reported Monday, citing a statement by the US State Department. US deputy secretary of state John Negroponte and China's Executive Vice Foreign Minister Dai Bingguo will lead their teams to the two-day US-China "senior dialogue" beginning Wednesday, said the statement. The dialogue is expected to cover the countries' bilateral relations as well as a range of key global issues, including security in Northeast Asia, energy and the environment, Iran and the conflict in Sudan's Darfur. The dialogue "is an important forum for both countries to discuss issues of strategic and political importance, including how to achieve our common goals," according to the statement. US President George W. Bush and Chinese President Hu Jintao agreed in 2004 during a summit of the Asia Pacific Economic Cooperation ( APEC) forum to hold the talks among their officials as part of efforts to improve ties. US-China ties are clouded by a variety of issues, including US accusations that China is keeping its currency undervalued. Currency concerns dominated a US-China "strategic" economic dialogue last month led by Chinese Vice Premier Wu Yi and US Treasury Secretary Henry Paulson even as unveiled measures to boost trade and investment ties.Despite criticism from the US in particular, Chinese officials contend that currency reforms are moving as quickly as the developing economy and financial system will allow.

BEIJING, March 21 (Xinhua)-- Personal computer giant Dell Inc. said Thursday that it will raise parts purchases from China by 27.8 percent this year, increasing its presence in the booming market.     Dell is to buy 23 billion U.S. dollars worth of computer components and other equipment from Chinese suppliers this year, compared with 18 billion U.S. dollars in 2007, said Michael Dell, chief executive officer of the PC giant, at a press conference.     However, Dell's Beijing representative office denied reports that the company was planning to buy 29 billion U.S. dollars of computer parts from China in 2009.     To secure a bigger share of the Chinese market, Dell broke with its Internet sales model and sealed a deal in September to sell PCs through the country's top electronics retailer, GOME Electrical Appliances.     Dell saw its PC shipments in China up 54 percent year-on-year in 2007.     The company plans to expand its retail outlets from 45 cities in 2007 to 1,200 by the end of the year.     China, where Dell ranks third in terms of market share, is one of the company's fastest growing markets, said Michael Dell.     Dell has two factories in Xiamen, a coastal city in southeastern Fujian Province, a design center in Shanghai and a customer contact center in Dalian, a northeast coastal city, with more than 6,000 employees in China.     Meanwhile, Dell estimates it will contribute more than 50 billion U.S. dollars to China's gross domestic product (GDP) this year, and provide about 2 million jobs.     Dell also said it would donate 1.7 million yuan (239,436 U.S. dollars) to build six education centers in China to teach computer skills to migrant workers' children.
