Shenzhen (China) (AFP) – Chinese telecoms giant Huawei said on Thursday it has petitioned a US court to overturn a ban that prevents carriers in rural America from tapping an $8.5-billion federal fund to purchase the company’s equipment.

Huawei’s petition said the ban — imposed last month against the company and its Chinese rival ZTE on national security grounds — failed to substantiate claims that Huawei was a threat and was a violation of due process.
