China's Huawei Technologies Co Ltd , the world's second-biggest telecommunications equipment maker, said it was negotiating the conditions under which it would agree to take part in a U.S. congressional hearing into alleged security threats posed by Chinese telecommunications companies, according to Reuters. The House of Representatives Intelligence Committee announced earlier on Thursday that it would hold an open hearing on Sept. 13 as part of its investigation into "the national security threats posed by Chinese telecommunications companies working in the United States." Huawei has received the committee's invitation to testify next week, "and will appear at the hearing if the appropriate arrangements are agreed with the committee," William Plummer, a company spokesman in Washington, said in a statement. He said in a telephone interview that the arrangements were still under negotiation with the committee but declined to elaborate. Plummer said Huawei looked to further contributing to a better understanding by panel members of the "globalized and interdependent" communications technology industry. Huawei also called attention to the work it said it is doing to promote "universal and industry-wide security assurance solutions." "The integrity of Huawei's operations and performance and the quality and security of our products are world-proven, across 140 markets," Plummer said. -- SPA
