HONG KONG (Reuters) - China's Tencent Holdings and Guangzhou Automobile Group Company Ltd have agreed to collaborate on internet-connected cars - a strategic pact that sent shares in Guangzhou Auto surging. The development of self-driving cars and fast-changing technology have set in motion a flurry of alliances between internet giants and automakers. Earlier this year, Tencent bought 5 percent of U.S. electric car maker Tesla Inc for $1.78 billion. Tencent and Guangzhou Auto will work together to develop internet-connected cars and artificial intelligence-aided driving, as well as explore investment in areas such as auto-related e-commerce, so-called new energy cars and auto insurance, the automaker said in a filing late on Monday. Guangzhou Auto said it aimed to tap Tencent's expertise in mobile payments, social networking, big data and artificial intelligence.
