The U.S. Defense Department said in early 2013 it suspected the Chinese military was behind a cyberattack targeting sensitive military networks. The Chinese government denied the allegations, saying it had an open relationship with the U.S. military.
U.S. Rep. Frank Wolf, R-Va., chairman of a House appropriations committee, said he was proposing legislation in a 2014 spending bill preventing technology companies from buying Chinese-made components.
He told online newspaper Politico the measure was "good legislation." White House officials, however, said Thursday the legislation may be "highly disruptive."
Bilateral cybersecurity issues were discussed last week at the working group level. The meeting was part of a broad-based annual strategic and economic dialogue between the U.S. and Chinese governments.
The House Foreign Affairs Committee scheduled a hearing Tuesday on the "cybersecurity battleground." A subcommittee on Asian affairs invited officials from computer security company McAfee as well as technology experts from the Center for Strategic and International Studies to testify.
