South Korea has agreed to route sensitive U.S. and South Korean communications away from networks that include equipment made by Huawei Technologies Co Ltd, spurred by Washingtons concerns over the Chinese firm, the Wall Street Journal reported on Friday. U.S. officials in meetings with South Korean counterparts in recent months raised the risk that Huaweis equipment could be used for spying on communications between the allies as well as compromise networks used by U.S. military and intelligence officials in South Korea, the report said. To address these security concerns, South Korea decided to make changes to the project so that sensitive South Korean government communications wont pass through Huawei equipment, the Journal quoted U.S. officials briefed on the discussions as saying.
