Rackspace's chief security officer said Wednesday it was critical for the United States to impose sanctions on China in response to alleged cyber attacks.
The White House is considering applying sanctions against companies and individuals in China it believes have benefited from Chinese hacking of U.S. trade secrets, The Washington Post reported last month.
Suspicions that Chinese hackers were behind a series of data breaches in the United States have been an irritant in relations between the world's two largest economies as President Xi Jinping prepared for his first visit to the United States, which commenced Tuesday.
White House officials said cyberspying will be a key part of discussions between President Barack Obama and Xi, but they do not expect the United States to level economic sanctions against China for cyberespionage ahead of Xi's arrival in Washington.

However, Rackspace's Brian Kelly said the time had come to get tough with China.
"It's troubling when we allow so many attacks to go without being answered for, particularly when we have pretty good evidence who may be behind the attack itself," he told CNBC's "Squawk Alley."
"So I think we do need to take a much stronger stance, and I think sanctions clearly are in order, beyond the indictments that we saw a year or two ago."
