By Michael Martina and Matthew Miller BEIJING/SHANGHAI (Reuters) – U.S. technology companies will likely bear the brunt of soured ties between Beijing and Washington over internet security, after the U.S. Department of Justice charged five Chinese military officers with cyber espionage. U.S. equipment and software providers such as IBM Corp and Cisco Systems Inc have already seen their China sales drop after last year’s revelations by former National Security Agency (NSA) contractor Edward Snowden of U.S. government spying. “The environment in China for U.S. technology companies is not very good right now, and this won’t make it better,” said James McGregor, chairman for advisory firm APCO China. “But if they’re losing their intellectual property to cyber hacking they probably see this action as necessary and worrisome.” IBM’s China sales have fallen by a fifth or more for three straight quarters, the Armonk, NY-based firm reported in April.
