Bank of China has taken a one-fifth share in the Edmond de Rothschild Finance Company for 236 million euros (342 million dollars), a spokesman for the European banking group told AFP on Thursday.
Bank of China, one of the four major Chinese banks, also acquired a further 10 percent stake through the issue of new shares in the Rothschild wealth management company.
Rothschild's French holding firm, the Saint-Honore Finance Company, will retain a majority stake, the spokesman said.
He said the new move would "open up the whole Bank of China network."
