BEIJING, Oct 11 (Reuters) - China, the world's biggest auto market, said on Monday it will roll out assessment measures to regulate data sent abroad by vehicles, as the country steps up efforts to protect data and privacy.As cars become 'smarter' with more in-car entertainment, information and autonomous driving functions, automakers and tech companies are gathering more data from vehicles, raising privacy and security concerns.China's Ministry of Industry and Information Technology did not offer details about how the assessment would be done. According to current rules, auto companies cannot export key vehicle data abroad unless they obtain approval from regulators.The ministry said regulators will improve monitoring of vehicle data security and encourage telecommunication companies to invest more in cyber security technologies.The move comes amid China's push to ensure the security of data as the proliferation of smart cars, such as Tesla (TSLA.O) electric vehicles, fuels concern about national security, in line with its broader aim to tighten policies around privacy.Beijing has been increasingly concerned over the mountains of data amassed by private firms and whether such information could be attacked or misused, especially by foreign states. It recently implemented a new data security law and is tightening up oversight in other related areas. read moreReporting by Brenda Goh and Yilei Sun; Editing by Subhranshu Sahu Disclaimer: The views expressed in this article are those of the author and may not reflect those of Kitco Metals Inc.
