The Wall Street Journal reports, "China's military ambitions have given its leaders growing confidence about their capabilities, according to a new U.S. assessment that warns that Beijing may believe it can wage a regional conflict while maintaining its expanded global presence. 'We now have to be able to look for a Chinese military that is active everywhere,' said a senior defense official who briefed reporters on the new report by the Pentagon's Defense Intelligence Agency. Washington and Beijing are engaged in a trade fight, and tensions over Taiwan persist, although the official said there is no indication that China is looking to take military action anywhere soon. 'But they are present in a lot of places and we will have to interact with them, engage with them, deal with them, monitor them more broadly than we've ever had to before when they were very regionally focused and near their own shores.'"
