UnionPay International released in Shanghai on Tuesday a list of 40 core business and retail districts favored by Chinese consumers, showing that South Korea and the United States are among the fastest-growing markets for outbound travelers.

The global bank-card company, a subsidiary of UnionPay Co Ltd, whose activities include cross-border transactions, said it has monitored Chinese consumers' preferences based on worldwide data.

The payment services provider said travel destinations of Chinese consumers have been expanded from the traditionally popular Southeast and East Asia to a much wider area that includes North Asia, North America and the Middle East.
