US-based semiconductor association claims Chinese tech firm has acquired at least two plants and is constructing three others

Huawei has been accused by a leading association of semiconductor manufacturers of building a collection of secret chip-making facilities across China to help the technology company bypass US sanctions, according to a report.

The Chinese tech firm moved into chip production last year and was receiving an estimated $30bn (£23.7bn) in state funding from the government, the Washington-based Semiconductor Industry Association was quoted as saying by Bloomberg, adding that Huawei had acquired at least two existing plants and was building three others.
