In his first interview with foreign media in nearly four years, Ren Zhengfei told reporters Huawei does not have regular contact with Beijing.

The recommendation came after Polish authorities arrested Huawei’s head of sales in Poland, Wang Weijing, and a former Polish intelligence agent on espionage charges.

The arrests came amid ongoing efforts by the U.S. and its allies to limit the use of technology manufactured by firms with ties to Beijing over espionage concerns.

The proposed bill comes as the government increases pressure on China for allegedly using its corporate presence in the U.S. to steal intellectual property.

“We do have concerns,” Rob Joyce says. “Those are based on real, grounded examples. They’re not things we’re going to carry out into the public because we need to be able to track those in the national security space.”

Hackers have chipped away at U.S. economic advantage through a steady campaign of stealing American intellectual property, according to a top NSA official.
