Chinese electric vehicle maker Nio and tech giant Tencent agreed to work together on areas including autonomous driving and high-definition mapping.

Tencent — a gaming, social media and cloud computing titan — has signed a cooperation agreement with Nio, one of Tesla’s rivals in China, as the firms look to cash in on Beijing’s focus on so-called new energy cars.

The partnership could allow Tencent to do this, while also giving Nio the technology backing of one of China’s biggest firms. Tencent is already a major investor in Nio, which is striving to differentiate itself from a sea of electric car start-ups.

Nio and Tencent said on Monday they will work together on high-precision mapping systems for drivers. Nio will also be using Tencent’s cloud computing infrastructure for data storage and training for autonomous driving. Driverless cars require huge amounts of real-time data to be processed in order to train algorithms.
