Despite regulatory obstacles in the US, Chinese vendor Huawei remains upbeat about its overall 2013 outlook, according to the Wall Street Journal, quoting the company’s wireless network marketing vp Bob Cai. Breaking into the US has been troublesome for the vendor: Several lawmakers claimed Huawei has failed to prove it is independent of the Chinese government. Huawei’s optimism comes from expected growth in the Asian and European markets, according to Cai. “The sheer fact that mobile operators across Western Europe are still sticking with Huewei—and there has never been any proof of actual security threats—means that it is very likely just a case of economics rather than a security issue,” said Yankee Group Senior Analyst Boris Metodiev. The good news is the demand for next-generation mobile networks is on the rise, especially with the adoption of 4G globally, he said, noting that Huawei is “one of the biggest mobile equipment manufacturers in the world.” The company will continue to grow in Asia and Europe, where its main operations are anyway, which will “easily offset the loss of business in the U.S.,” he said.
