China's Ministry of National Defense blasted the U.S. over recent allegations that it has been spying on Huawei Technologies, and said it plans to shore up the nation's Internet security in response. Recent reports on U.S. spying activities against China, its businesses, and people, expose the U.S.'s "hypocrisy" and "tyranny," said Defense Ministry spokesman Geng Yansheng at a press briefing on Thursday.
