Will US ban Chinese from hacker event?

Washington is considering using visa restrictions to prevent Chinese nationals from attending popular hacking conferences in Las Vegas as part of a broader effort to curb Chinese cyber espionage.

An official said that Washington could use such visa restrictions and other measures to keep Chinese from attending the August Def Con and Black Hat events to maintain pressure on China after the US charged five Chinese military officers with hacking into American companies to steal trade secrets. China has denied the charges, saying they were “made up.”
