Costco Wholesale Corporation (Costco), the world’s second-largest retailer, officially entered the Chinese market in Shanghai in August 2019. The opening day was so jam-packed with customers that the massive influx forced the company to close early, after only five hours of operations.

What caused this situation? Did Costco make the right decision to enter the Chinese market? Does Costco’s membership system fit the Chinese market? What kinds of challenges will Costco face in the future?
