BEIJING, Nov. 25, 2005（Reuters）— China’s home-grown human bird flu vaccine① is at least a year away from hitting the market but tests on humans have been approved by the government, head of the research drug company said on Friday.

       Development of the vaccine started last year after bird flu outbreaks in Thailand and Vietnam and animal trials have already been completed, said Yin Wei-dong, managing director of Sinovac Biotech.

       “It is not a virus that is spreading from human to human，so we are very optimistic②,” Yin told Reuters in an interview.

       The deadly H5N1 made its first known jump to humans in Hong Kong in 1997, killing six people. The virus appeared again in late 2003 and is known to have infected 130 people in several parts of Asia, killing 68 of them.

       “It is not decided yet when the human trials will begin. We just got approval on November 22 by the State Food and Drug Administration,” Yin said.

Oregon, Nov. 26, 2005（AP）— The deadly strain of bird flu that appeared in Asia and has already spread to other parts of the world has not affected the Oregon poultry③ industry or consumers, according to Oregon State University researchers.

       There are many strains of bird flu that do not usually infect humans. But one strain, called H5N1, has jumped from chickens to humans and is blamed for more than 60 deaths in Asia.

       International disease control experts are worried about a worldwide outbreak of bird flu, raising concerns such as whether it is safe to eat poultry.

       But Oregon State University researchers say there is no proof that the virus can jump to humans by eating cooked poultry products.

       “Consumers needn’t be overly concerned about bird flu,” said Jim Hermes, OSU Extension Service poultry specialist. But he urged consumers to follow standard food safety practices in preparing poultry — including washing hands while preparing food, and proper cooking of poultry meat and eggs.

       He noted that a 2003 outbreak of bird virus caused much damage to commercial poultry operations in California but did not get into Oregon because of industry safeguards.

President Clinton’s decision on Apr.8 to send Chinese Premier Zhu Rongji packing without an agreement on China’s entry into the World Trade Organization seemed to be a massive miscalculation. The President took a drubbing from much of the press, which had breathlessly reported that a deal was in the bag. The Cabinet and Whit House still appeared divided, and business leaders were characterized as furious over the lost opportunity. Zhu charged that Clinton lacked “the courage” to reach an accord. And when Clinton later telephoned the angry Zhu to pledge a renewed effort at negotiations, the gesture was widely portrayed as a flip-flop.

In fact, Clinton made the right decision in holding out for a better WTO deal. A lot more horse trading is needed before a final agreement can be reached. And without the Administration’s goal of a “bullet-proof agreement” that business lobbyists can enthusiastically sell to a Republican Congress, the whole process will end up in partisan acrimony that could harm relations with China for years.

THE HARD PART. Many business lobbyists, while disappointed that the deal was not closed, agree that better terms can still be had. And Treasury Secretary Robert E. Rubin, National Economic Council Director Gene B. Sperling, Commerce Secretary William M. Daley, and top trade negotiator Charlene Barshefsky all advised Clinton that while the Chinese had made a remarkable number of concessions, “we’re not there yet,” according to senior officials.

Negotiating with Zhu over the remaining issues may be the easy part. Although Clinton can signal U.S. approval for China’s entry into the WTO himself, he needs Congress to grant Beijing permanent most-favored-nation status as part of a broad trade accord. And the temptation for meddling on Capital Hill may prove over-whelming. Zhu had barely landed before Senate Majority Leader Trent Lott (R-Miss) declared himself skeptical that China deserved entry into the WTO. And Senators Jesse A. Helms (R-N.C.) and Emest F. Hollings (D-S. C.) promised to introduce a bill requiring congressional approval of any deal.

The hidden message from these three textile-state Southerners: Get more protection for the U. S. clothing industry. Hoping to smooth the way, the Administration tried, but failed, to budge Zhu on textiles. Also left in the lurch: Wall Street, Hollywood, and Detroit. Zhu refused to open up much of the lucrative Chinese securities market and insisted on “cultural” restrictions on American movies and music. He also blocked efforts to allow U. S. auto makers to provide fleet financing.

BIG JOB. Already, business lobbyists are blanketing Capitol Hill to presale any eventual agreement, but what they’ve heard so far isn’t encouraging. Republicans, including Lott, say that “the time just isn’t right” for the deal. Translation: We’re determined to make it look as if Clinton has capitulated to the Chinese and is ignoring human, religious, and labor rights violations; the theft of nuclear-weapons technology; and the sale of missile parts to America’s enemies. Beijing’s fierce critics within the Democratic Party, such as Senator Paul D. Wellstone of Minnesota and House Minority leader Richard A. Gephardt of Missouri, won’t help, either.

Just how tough the lobbying job on Capitol Hill will be become clear on Apr. 20, when Rubin lectured 19chief executives on the need to discipline their Republican allies. With business and the White House still trading charges over who is responsible for the defeat of fast-track trade negotiating legislation in 1997, working together won’t be easy. And Republicans—with a wink—say that they’ll eventually embrace China’s entry into the WTO as a favor to Corporate America. Though not long before they torture Clinton. But Zhu is out on a limb, and if Congress overdoes the criticism, he may be forced by domestic critics to renege. Business must make this much dear to both its GOP allies and the Whit House: This historic deal is too important to risk losing to any more partisan squabbling

After a 15-year ban on the sale of fireworks in Beijing, Kang Guoliang, 51, was able to start his old trade again yesterday．

As a salesman in Xinhui store in Dongcheng District, he is happy about the increasing number of buying fireworks wrapped in red paper — a color standing for happiness and good luck．

“Fireworks are available for the first time in town for more than a decade,” Kang said happily．“People will buy them．”

The store has 300 boxes of fireworks piled up and is open 24 hours at the moment．Residents are buying the fireworks and firecrackers for the upcoming Spring Festival, which falls on February 18．

Citywide, 2,116 registered stores and retailers, 585 in the centre and 1,600 on the outskirts are trading fireworks in the Chinese capital．Sales of fireworks within the Fifth Ring Road started yesterday and will last until March 4, Xinhua reported．Among the stores, 117 stores are permitted to operate 24 hours．About 600,000 boxes of firecrackers worth more than 100 million yuan have been carried to registered stores．

The Chinese capital began a ban in 1993 to reduce fireworks-related deaths and fires during the holiday season．Last September the ban was removed in response to residents’ fondness for fireworks when celebrating Spring Festival．

According to new rules, Beijing residents are allowed to set off fireworks within the Fifth Ring Road all day on Lunar New Year’s Eve and Lunar New Year’s day, from 7 a．m．to midnight every day from February 19 to March 4．

“Spring Festival without fireworks is not Spring Festival,” said Sheng Hefei, who was buying fireworks in the store．“It was fun to light the firecrackers when I was little,” he said．“The sound and view of fireworks make a real holiday．” However, not all residents welcome the return of firecrackers because of injuries, pollution and noise．“My child is scared of the sudden sound of firecrackers, and it is annoying to hear it all night long,” complained Lu Jun, a local resident．
