Dow JonesSHANGHAI — Credit Suisse First Boston executives said last week that China had dropped the company from a multibillion dollar share offering because the Zurich investment bank hosted two overseas conferences in which senior officials from Taiwan took part.

They said the offering in question had been expected later this year for Unicom Group Ltd., China’s second largest telecommunications company, and that Credit Suisse was to handle the offering’s U.S. portion.

A senior Credit Suisse executive who did not want his name to be used said the investment bank also fears it could be dropped from at least two other potential underwriting deals in China.

Executives at Unicom and officials at the China Securities Regulatory Commission would not discuss the matter. Officials at China’s State Council Information Office, which handles foreign news inquiries, did not respond to faxed questions. A Credit Suisse spokeswoman in Hong Kong, Josephine Lee, said the company had “no comment.”
