BEIJING, Nov. 2 (Xinhua) -- Stocks on ChiNext, the country's Nasdaq-style board for domestic start-up firms, rode on a roller coaster on the first two trading days: soaring at debut and taking a sudden turn on the second day.     Twenty stocks out of the total 28 fell by the daily limit of 10percent at Monday close, compared with an average of 106.23 percent surge on Friday, the first trading day, driven by a speculative surge for quick profits.     About 252,600 individual investors bought 423 million new shares at ChiNext on Friday, accounting for more than 97 percent of all new shares on the market.     The average price-earnings ratio for the initial public offering prices was at around 55.70 times, and then was pushed up to around 111 times, much higher than 25.98 times and 37.80 times at main boards in Shanghai and Shenzhen bourses respectively.     The bubbly opening led to warnings of risks posed by excessive speculation and inflated stock price.     Jin Yanshi, chief economist with the Sinolink Securities, said the price-earnings ratio was too high driven by the irrational buying spree. He said the frenzy would gradually cool off, and he expected a 30 percent to 50 percent drop of share prices in three to six months.     Analysts said it was typical in China that new shares would face speculation at debut and see large initial gains, followed by a continuous pullback.     China State Construction Engineering Group shares soared more than 60 percent at debut in Shanghai on July 29 from a initial public offering price of 4.18 yuan and ended at 6.53 yuan, up 56.22 percent. On Monday, its close price stood at 4.79 yuan.     It also reminded of the launch of board for small and medium-sized enterprises at Shenzhen Stock Exchange market on June25, 2004, when shares of eight new stocks rose more than 130 percent. The share prices fell by an accumulative 40 percent from the close prices on the first trading day three months later.     China made plans to launch the Nasdaq-style board for trading of start-up shares in 1999 to boost development of small and medium-sized enterprises. The plan was postponed in 2001 when the Internet bubble burst in the United States.     Since 1962, a total of 39 nations or regions have launched 75 such boards for start-up companies to raise funds. However, about half of them ended up closing due to weak market sentiment and regulatory inconsistencies, and 41 markets were operational as of the end of 2007.     The Growth Enterprise Market, kicked in Hong Kong in 1999, was a luck luster as investors were scared away by the plunge in value of technology stocks in 2001. The index fell about 90 percent since then.     By contrast, Nasdaq set up in the United States in 1971 has been a successful one, which attracted giants like Microsoft and Intel, and became the major market for overseas listing of Chinese enterprises. There are currently 116 Chinese companies listed on Nasdaq, including Baidu.     Analysts attributed the main reasons for failure of some markets to blindly lowering threshold of market entry, poor supervision and inactive transaction.     The wild fluctuation challenged the ability of regulators to control volatility in the new bourse and stirred concerns whether it would grow to be a second Nasdaq or the dazzling debut would be the last wild ride.     Shang Fulin, chairman of the China Securities Regulatory Commission said on Oct. 23 that trading on the new board may have a probability of becoming "irrational" than on other bourses.     "Preventing risk is our main task," he said. "We'll make sure risk is estimated, detected and controlled."     The Shenzhen Stock Exchange issued special suspension rules to clamp down on speculation. Trading would be suspended for 30 minutes if share price rises or falls by 20 percent from its debut level. If a stock fluctuates again beyond 50 percent of its opening price, it will be suspended for 30 minutes. The stock can also suspend a stock until three minutes before the close of trading session on a rise or drop above 80 percent.     Zuo Xiaolei, chief economist of the China Galaxy Securities, said the lesson from failure of other markets showed the key to the success of such start-up board was to strengthen supervision while completing rules, which would ward off excessive speculation and rule violations.     The government should develop more policies to attract more firms with great potential growth to make the board bigger and stronger, but threshold for access to the market should not be lowered, analysts said.

SHANGHAI, Nov. 16 (Xinhua) -- U.S. President Barack Obama on Monday called on the Chinese and U.S. governments to strengthen cooperation in dealing with such global challenges as climate change.     "There are very few global challenges that can be solved unless China and the United States agree," he stressed while answering a question at a town hall with Chinese students in Shanghai, the first stop of his four-day China tour.     As the world's two largest greenhouse gas emitters, the United States and China should assume the responsibility to curb greenhouse gas emissions, he said.     "Unless both of our countries are willing to take critical steps in dealing with this issue, we will not be able to resolve it," Obama said.     The president called on world leaders to strike a deal at the December Copenhagen conference during which they would make differentiated commitments to reducing greenhouse gas emissions.     China should not take the same obligations as the United States since it has a much larger population living in poverty, he said.     Climate change is expected to be one of the main topics at the upcoming meeting between Obama and Chinese President Hu Jintao.     President Hu promised at a September UN climate summit in New York that China would cut carbon dioxide emissions per unit of gross domestic product by "a notable margin" by 2020 from the 2005level.     Obama has said he wants to cut U.S. emissions back to 1990 levels by 2020 and 80 percent further by 2050, but the U.S. Congress was unlikely to complete climate legislation by the time of Copenhagen, due to great political challenges in the midst of a recession with high unemployment and other domestic priorities.     According to U.S. top negotiator Jonathan Pershing, it would be difficult for the U.S. to pledge an emissions target without legislation by Congress, therefore a new pact to combat global warming is a forlorn hope for Copenhagen.     The Dec. 7-18 Copenhagen meeting, which is expected to bring together leaders from 190 countries, aims to renew greenhouse gas emissions reduction targets set by the Kyoto Protocol, due to expire in 2012. 

ROME, Jan. 8 (Xinhua) -- Chinese Ambassador Sun Yuxi announced Chinese culture year in Italy at a press conference at the Chinese embassy here Friday.     The culture year, which follows Italian year in China in 2006, will officially start in September.     "The Chinese culture year in Italy is set to be a central obelisk supporting further exchange between the two countries. It is a crucial project on which both governments have long been working," said Sun.     The ambassador said nine Chinese central government departments and 22 local authorities would be involved in organizing more than100 events all over Italy, including performances of traditional Chinese musical bands, dances and operas. Chinese Ambassador to Italy Sun Yuxi (R) addresses a press conference about the Chinese cultural year to be held in Italy, in Rome Jan. 8, 2010    Meanwhile, business conferences will offer opportunities for important meetings between Chinese and Italian entrepreneurs and facilitate trade agreements.     The Italian government has nominated former culture minister Giuliano Urbani as coordinator of the organizing committee, which is composed of representatives from 13 Italian government ministries.     Sun said 2010, which marks the 40th anniversary of diplomatic relations between China and Italy, is set to be a crucial year for political and economic ties.     China-Italy ties were "in the best period ever in the history of diplomatic relations," the ambassador said.     Cooperation at all levels had recently been enhanced and Italy was a crucial partner for China, he added.     The press conference was the first of a series preparing the ground for the Chinese culture year in Italy.     The ambassador is scheduled to give a press conference at the beginning of each month of this year.

ZHENGZHOU, Nov. 10 (Xinhua) -- Chinese President Hu Jintao has urged to establish and improve the mechanism of democratic self-governance of villages that can both secure the Communist Party's leadership and safeguard villagers' rights.     In a recent written instruction, Hu called on local officials to make efforts to improve the grassroot governance mechanism in rural areas in line with the basic conditions of the country.     Other leaders including Vice President Xi Jinping have also made similar instructions.     In a meeting on Tuesday in Zhengzhou, capital of central China's Henan Province, Li Yuanchao, head of the Organization Department of the Communist Party of China Central Committee, urged officials to study the leaders' instructions.     The building of grassroot governance organizations in rural areas must be strengthened, and the village-level democracy and self-government mechanism must be further improved, Li said.
