China's Tencent Holdings Ltd has bought a five percent stake in US electric car maker Tesla Inc. for 1.78 billion dollars, the latest investment by a Chinese internet company in the potentially-lucrative market for self-driving vehicles and related services.
Tencent's investment, revealed in a US regulatory filing, provides Tesla with a deep-pocketed ally as it prepares to launch its mass-market Model 3.
Tencent could also help the US company sell - or even build - cars in China, the world's largest auto market, analysts said.

"It certainly is a strong chess move for Tesla," said Jeff Schuster, senior vice president of forecasting for researcher LMC Automotive, citing the cash infusion and "help in navigating the Chinese market."
Tesla Chief Executive Officer Elon Musk on Tuesday tweeted: "Glad to have Tencent as an investor and adviser to Tesla." Musk did not say what he meant by "advisor," but in a separate tweet, he noted Tesla had "very few" Model 3 orders from China, where the car has not been formally introduced.
The midsize Model 3 is due to go on sale later this year in the United States.

The deal expands Tencent's presence in an emerging investment sector that includes self-driving electric cars, which could enable such new modes of transportation as automated ride-sharing and delivery services, as well as ancillary services ranging from infotainment to e-commerce.
Those new technologies, and their potential to create new business models and revenue streams in the global transportation sector, have attracted billions in investment from China's three tech giants - Tencent, Alibaba Group Holding Ltd and Baidu Inc.
Founded in 1998 by entrepreneur Ma Huateng, Tencent is one of Asia's largest tech companies, best known for its WeChat mobile messaging app. With a market capitalization of about 275 billion dollars, it is roughly six times the size of 14-year-old Tesla.
Tencent was an early investor in NextEV, a Shanghai-based electric vehicle startup that since has rebranded itself as Nio, with US headquarters in San Jose, not far from Tesla's Palo Alto base.
In addition, Tencent has invested in Didi Chuxing, the world's second-largest ride services company behind Uber, and in Lyft, Uber's chief US rival.
Baidu has invested in Nio, as well as in Uber and Velodyne, a California maker of laser-based lidar sensors for self-driving cars. Alibaba's mobility investments include Didi and Lyft.
As Tesla is doing, many of the start-up companies backed by Tencent, Baidu and Alibaba are developing self-driving systems that eventually could be introduced in commercial ride-sharing fleets in the United States and China after 2020.
Tencent maintains a US office in Palo Alto, in the heart of California's Silicon Valley. Beijing-based Baidu and Hangzhou-based Alibaba also maintain offices in Silicon Valley.
Tencent owns about 8.2 million shares in Tesla, the carmaker said. It is the fifth-largest shareholder, behind Musk and investment companies Fidelity, Baillie Gifford and T. Rowe Price.
