     BEIJING - After a night of wining and dining with 50 of China's richest people, Warren Buffet and

Bill Gates told the journalists on Thursday that the biggest difference between eating with Chinese

tycoons (企业界大亨) and Western ones was the food.

     "I was amazed last night, really, at how similar the questions and discussions and all that were to those

in the dinners we had in the U.S.," said Mr. Buffett.

     Mr. Buffett and Mr. Gates, two of the best known Westerners here, announced in September, 2010

that they planned to invite 50 wealthy Chinese tycoons to dinner in Beijing to encourage philanthropy (慈善事业) among China's new rich.

     On Thursday, the two men pronounced the dinner a great success, saying that two-thirds of those

invited had shown up, and that more than half of them had offered their own ideas on how Chinese

philanthropy should work.

     The guest list wasn't made public, but the Chinese news media reported that it included Jet Li, the

movie star; Niu Gensheng, the founder of a Chinese dairy business; and Pan Shiyi and Zhang Xin, who

control the SOHO China real estate (房地产) empire.

     As with four earlier dinners held in the United States, Mr. Buffett and Mr. Gates said, no one at the

Beijing event was asked to donate money or to promise to engage in charity. "Bill and I won't be calling

anybody. What happens in China will depend on what the Chinese people feel about a project of this

sort," said Mr. Buffett.

     China is widely reported to be second only to the United States in the number of dollar billionaires.

Mr. Gates and Mr. Buffett said the nation was unique because its wealthy class had arisen almost wholly

in the past 30 years, so the philanthropic practices established among European and American dynasties

are new here, and open to change.

     The two said the dinner wasn't a long planned matter, but an offshoot (衍生事物) of a trip that Mr.

Buffett had already scheduled to Guangdong and Hunan Provinces, where BYD Company, a maker of

clean-energy automobiles, has factories. Mr. Buffett's company, Berkshire Hathaway, holds a 10%

stake (股金) in the company.

     But Mr. Gates suggested that their philanthropic trip wasn't yet over. "We may do an event in India,"

he said.
