Stunning Number That Shows Uber's Growth in China in 1 Year

— -- Uber's car service has exploded to 58 countries in five years of its launch, though not without hiccups. But its "unprecedented" growth in China in the last year is nothing short of jaw-dropping.

This week, Uber CEO Travis Kalanick revealed that the company is providing nearly 1 million trips per day in China, where the company launched in February 2014. In a message to investors, obtained by the Financial Times, Kalanick revealed that Uber's business in China doubled in the last month.

Just last week, Uber, based in San Francisco, celebrated its fifth anniversary, but already four of Uber's 10 largest cities are in China. The company compared its growth in five Chinese cities to New York. At the six-month mark, the number of trips in Chengdu was 46 times larger than that of New York at the same "age," according to Kalanick. After nine months, Chengdu city had 479 times the number of trips that New York did.

"Our early success derives from an organic approach to the market -- we have established a new Chinese entity, Youbu, (which means “an excellent step forward”), and have partnered with Baidu to create a truly Chinese company that is built and supported by local employees, local partners, and local investors," he wrote.

Uber did not respond to a request from ABC News for further comment.

"This kind of growth is remarkable and unprecedented," Kalanick wrote. "To put it frankly, China represents one of the largest untapped opportunities for Uber, potentially larger than the U.S. Success in China, however, takes commitment over the long haul and a strong will, coupled with a unique understanding of the differences in China."

Uber has faced regulatory hurdles in countries such as France that view the service as an unauthorized taxi or a threat to the traditional cab industry.

Uber is in 11 cities in China so far, but the company plans to launch in 50 more cities this year that have a population of more than 5 million.
