WASHINGTON, Feb 13 (Reuters) - The Trump administration on Friday withdrew an updated version of its list of Chinese military-backed companies that was posted earlier on Friday and included Chinese tech giants Alibaba and Baidu. 

It was not immediately clear whether the withdrawal indicated a change of policy. The Pentagon did not immediately respond to a request for comment.
