Didi Chuxing has announced a historic deal to acquire the Chinese ride-sharing operations of rival Uber, which threw in the towel after years of unsuccessful efforts to grow its business in what may prove to be the world's most challenging technology market. Under the agreement, Didi Chuxing acquired all of Uber China's assets, including its brand, data and business operations. The deal calls for Uber to receive 5.89 percent of the combined entity with preferred equity interest, which is the equivalent of a 17.7 percent stake in Didi Chuxing.
