Huawei, the Chinese telecoms giant, on Tuesday said the U.S. has launched cyber attacks against it to infiltrate intranet and internal information systems as it denied a series of allegations. Huawei also denied allegations in a report in the Wall Street Journal that it stole smartphone-camera patents. "The fact remains that none of Huawei's core technology has been the subject of any criminal case brought against the company, and none of the accusations levied by the U.S. government have been supported with sufficient evidence. We strongly condemn the malign, concerted effort by the U.S. government to discredit Huawei and curb its leadership position in the industry," the company said in a statement.
