Interdigital (IDCC.NASDAQ), a US patent-licensing company that is embroiled in a legal dispute with Chinese telecoms equipment maker Huawei, claimed that China’s antitrust authorities have threatened to arrest representatives of the company, Financial Times reported. The company said it had been warned by the China’s National Development and Reform Commission that any executives or legal representatives who attend a meeting that was due to take place in Beijing today might be detained or arrested. The claim comes as NDRC takes a more assertive stance on enforcing the country’s monopoly laws against foreign companies.
