The trade union suspects the fake Goldman Sachs has links to organized crime syndicates operating in Macau.
In addition to using the Goldman Sachs' name in English, the Shenzhen firm's Chinese name uses the characters gao sheng, which mean "high" and "prosperous." The real Goldman Sachs uses the same characters in its Chinese name.
China has a long history of churning out knockoffs, or "shanzhai."
In August, a 39-year-old man in eastern China was arrested for establishing a fake branch of China Construction Bank, the world's second largest bank by assets. The operation had card readers, teller counters and authentic-looking signs.
The ruse was discovered only when a local who had deposited 40,000 yuan ($6,200) was unable to withdraw the money at the real China Construction Bank, according to state media reports.
