A senior banker at Nomura Holdings has been barred from leaving China in a move connected to a long-running investigation of a top dealmaker in the country, the Financial Times reported.

Charles Wang Zhonghe, who is chair of investment banking for China at the Hong Kong arm of the Japanese bank, has not been detained and is only restricted from exiting China, the newspaper reported, citing people familiar with the matter it didn’t identify. Nomura declined to comment and Wang didn’t immediately reply to a request for comment, the Financial Times said.

"I am not aware of what you mention,” Wang Wenbin, a spokesman at the Chinese Ministry of Foreign Affairs, said Monday. "I want to reiterate that China is committed to providing a market-orientated, law-based and internationalized and sound business environment to companies operating in China.”
