Johnson & Johnson has bought top Chinese cosmetics firm Beijing Dabao, the firm said on Wednesday, wrapping up a deal estimated at more than $300 million and aimed at expanding the US giant’s shares in the Chinese market.

Johnson & Johnson, which vies with the likes of Unilever to sell cosmetics and healthcare products to a retail consumer market growing at double digits annually, won a bidding war with Avon and Unilever and will pay 2.3 billion yuan ($337 million) for Dabao.

The US firm did not disclose the financial terms for the completed acquisition on Wednesday.

China’s fragmented cosmetics and healthcare market hosts more than 3,500 distinct brands, local newspapers have reported.

But global consumer and healthcare product firms such as Procter & Gamble are nonetheless pondering acquisitions in China to shore up and expand market share, with rip-roaring economic growth creating a newly monied middle class.

Underscoring the market’s attraction, L’Oreal bought popular local brands Mini Nurse and Yue Sai in 2004.

Dabao, a firm owned by the Beijing Sanlu Factory, cranks out a variety of self-branded, herbal cosmetics from skin cream to hair products. It exports to more than 30 countries, including the United States and Japan, according to its Web site.

In 2006, the firm posted a meagre 41.7 million yuan ($6.1 million) of net profit on sales of 675.2 million.

John McCain accused Barack Obama of playing politics with race on Thursday, raising the explosive issue after the first black candidate with a serious chance of winning the White House claimed Republicans will try to scare voters by saying he “doesn’t look like all those other presidents on the dollar bills.”

BEIJING, Aug. 1 — Another 10 percent Beijing vehicles will go off the roads if the weather is “extremely unfavorable” during the Olympic Games, the Ministry of Environmental Protection has said.

The traffic restriction already in force allows vehicles with even and odd license numbers to hit the roads only on alternate days, reducing them by half.

The emergency measure would make private cars whose last two license plate digits match the date (between August 8 and 24) to be off the roads. This could reduce the total number of private cars on the capital’s roads by 60 percent.

Other emergency steps include temporarily closing 105 more factories and stopping all construction work in the city. Another 56 factories in Olympic co-host city Tianjin and 61 in Hebei province will be closed, too.

Earlier, independent experts had suggested the environmental authorities take up to 90 percent cars off the roads if the air quality does not improve during the Games.

Zhu Tong, an environmentalist advising the city government, told the Beijing News yesterday: “Though the final emergency plan will not be as effective as the one in which 90 percent cars would have been banned, the government must have considered the interests of all sides.”

It’s not common for Beijing to experience sultry weather like it did last week, Zhu said.

But “our independent study shows Beijing’s long-term efforts have worked”.

Yesterday’s air pollution index (API) was 69, much healthier than what it was a couple of weeks ago, before the even-and-odd license plate number restriction was imposed. Wednesday’s API was even better at 44.

BEIJING, Aug. 1 — Beijing will handle up to 1,500 flights and 260,000 passengers a day, the most its airport can cope with, in the run-up to and during the Olympic Games, Civil Aviation Administration of China (CAAC) officials have said.

The challenge Beijing faces is evident from the fact that Athens handled 795 flights and 58,000 passengers on the eve of the 2004 Games’ opening.

Adding to the challenge is the threat of thunderstorms on Aug 8 and 9, according to a study based on the city’s decades-long weather data, said Huang Dengke, of the CAAC North China regional administration and in-charge of the airport’s Games time coordination.

But contingency plans are in place, with four airports in North China chosen to handle some of the flights if Beijing encounters bad weather or air traffic congestion, Huang said. The four airports are in Tianjin, Shijiazhuang, Taiyuan and Hohhot, and together they have 100 parking bays ready for emergency landings.

The CAAC has imposed a five-hour air traffic ban at the Beijing airport between 7 pm and midnight on Aug 8, the opening day of the Games, in line with the practice adopted by previous host cities, CAAC deputy head Yang Guoqing said.

The CAAC estimates that the busiest time for aviation and airport authorities will be between Aug 6 and 11, and peak on Aug 7.

The number of landings and take-offs will increase by 20 percent, compared with normal days, during the period, and the volume of passengers by 25 percent, Yang said.

To cope with the unprecedented increase in the number of flights and passengers, part of Terminal 3 will only receive Olympic guests, including more than 10,000 athletes. Terminal 3 is the world’s largest and was opened in March.

The newly built VIP terminals will handle special flights carrying 80 heads of state, and 160 chartered and 1,000 business flights.

Yang said the increase in the number of special flights will not disrupt ordinary passenger flights.

The CAAC has tightened security checks at airports since July 20 to foil any terrorist attack. It has been collaborating closely with other departments to verify and analyze information on possible terrorist threat, Yang said.

Some international terrorist groups, including the Eastern Turkistan Islamic Movement, have threatened to attack Olympic venues. Security officers in the Xinjiang Uygur autonomous region busted a terrorist plot to hijack a plane bound for Beijing this March.

But airport manager Zhang Zhihong said security forces are ready to deal with any eventuality. “We will ensure 100 percent security for the airport and the Games,” he told journalists at the airport.

BEIJING, July 31 (Xinhua) — Rail fans and passengers queued upon Thursday morning to buy tickets for Friday’s debut of the world’s fastest intercity rail line linking Beijing with Olympic co-host city Tianjin.

Tickets were available at the Beijing Railway Station, the Beijing West Railway Station and other ticket outlets. But at the Beijing South Railway Station, where the first train would leave from, ticket sales were expected to start later on Thursday, station staff told Xinhua.

The Ministry of Railways (MOR) announced on Wednesday this ultra-modern line would go into service on Aug. 1, one week before the Games begin.

The first train would leave the Beijing South Railway Station at about 11 a.m. after an official launch ceremony, the Beijing Times reported.

After regular service begins on Aug. 2, the first train would leave Beijing for Tianjin at 6:15 a.m., according to a time schedule provided by the Beijing South Railway Station. Twenty minutes later, another train would leave the Tianjin Station for Beijing.

The final train would leave Beijing for Tianjin at 10:10 p.m. while in Tianjin, the final train would depart at 10:06.

During regular services, there would be 47 pairs of trains every day. Trains bound for Tianjin would leave at various intervals of 15, 20 and 30 minutes.

A first-class ticket costs 69 yuan while the price for a second-class ticket is 58 yuan, Vice Railway Minister Wang Zhiguo told a press conference. Fares would be unchanged in the first year of operation.

The line would be the world’s only line on which passenger trains could run at 350 km per hour, Wang said. It would also be the first high-speed intercity rail line in China.

The railway, on which construction started in July 2005, was built at a total cost of 21.5 billion yuan (3.1 billion U.S. dollars), said Wang.

About 100 km of the line, or 86 percent, was built on an elevated alignment because of the area’s alluvial soil, which was sensitive to ground settlement.

The new service would cut the 120-km journey from the current 70 minutes to about 30 minutes, according to Wang. There are five stations along the line: the cavernous new Beijing South Railway Station, Yizhuang, Yongle, Wuqing and Tianjin.

The train is classified by the MOR as C-category, with C standing for Chengji, meaning intercity.

There will be 10 trains of eight cars that can seat about 600 passengers. These sleek trains, with aircraft-like cabins, swivel seats, spacious interiors and rooftop solar panels, were built by the Sifang Locomotive and Rolling Stock Company.

Called the CRH-3 (China Railway High-speed), these were China’s first self-designed and self-manufactured passenger trains.

The MOR had said about 26 million passengers traveled between the two cities every year, and this new line was forecast to raise the figure to 32 million in 2008.

Wang said more trains would be put into service in the future as the signal system allowed trains at minimum intervals of three minutes.

At least three kinds of trains already run between the two cities.

D-category trains run at 200 to 250 km per hour and take 70 minutes. Passengers pay 51 yuan for a first-class seat and 42 yuan for a second-class seat.

K-category trains run slower and take 100 minutes. The maximum fare is 20 yuan.

A third category runs only during major holidays, such as the Lunar New Year, and supplements regular services
