For foreign retail brands that aim to enter China, the growing second-and third-tier cities can be sources of new growth. But it is important that the brands be well-known and attractive.

And as e-commerce is booming in China, online and offline operations should go hand-in-hand.

Thanks to higher wages, increasing urbanization and improved living standards, the rise of the Chinese consumer became an increasingly important story over the past decade.

Global consultancy firm McKinsey & Co estimated that 75 percent of China's population will be classified as middle-class consumers by 2022, compared with just 4 percent in 2012. China will surpass the United States as the world's largest retail market within the next three years, according to a report by PricewaterhouseCoopers LLC and the Economist Intelligence Unit released in February.

Retail sales growth will hit 7.9 percent by 2018, compared with 2.6 percent for North America and a global average of 3.4 percent, the report said.

While many foreign companies and brands have focused on first-tier cities such as Shanghai, Beijing and Guangzhou, China has many second-and third-tier cities that are among the world's largest urban retail markets. But many foreign companies have yet to tap into these markets.

The lower-tier cities are not so developed as first-tier ones, but they are less saturated markets. Nonetheless, they have many increasingly sophisticated and well-heeled consumers.

People in these cities have a strong interest in spending on higher-end products and services, and they are open to trying new as well as famous brands.

The lower-tier cities are experiencing retail growth that is even faster than in the first-tier cities.

For example, Digital Luxury Group, an international branding company, found that in western China, largely comprised of third-tier cities, more people are searching for high-end brands than in first-tier cities including Shanghai.

The majority of China's emerging urban middle class resides in cities outside the first-tier ones. As a result, foreign retailers have begun to broaden their search for growth by expanding into less-developed regions.

Some foreign retailers even skip the first-tier cities and head straight for the lower-tier ones.
