Firm tied to China's fallen copper king sells Singapore office

A Singapore-based commodities trading firm linked to troubled Chinese copper tycoon Wang Wenyin has sold the top three floors of a prime office building in the Central Business District for $91.8 million, according to property transaction documents.

Awin Resources International, a trading affiliate of Mr. Wang's Amer International Group, sold the office at 20 Collyer Quay to a subsidiary of developer GuocoLand earlier in March, according to official records seen by Bloomberg.

Awin was founded by Mr. Wang's family in 2011, and his son is currently listed as the company's sole director.

Mr. Wang—nicknamed "copper king" in his heyday, when his sprawling group was said to handle a tenth of China's copper imports—has stumbled in recent years, suspending regular metals trading and closing factories.
