Didi Chuxing is restructuring for the second time in a year, placing new emphasis on safety and user experience to jump-start domestic growth in its ride-hailing business.

The management changes, which include a new chief safety officer and a new chief customer officer, come after two passengers were killed in separate incidents in China last year, leading to a drop in business. At the same time, Didi is shifting resources to overseas markets such as Latin America, where the Chinese giant competes with Uber and has seen strong growth.
