China has appealed to the US to treat its companies fairly, after the Committee on Foreign Investment in the United States (CFIUS) ruled against Huawei’s patent deal with 3Leaf Systems, the Financial Times reported. "We hope the US security examination laws and regulations can treat a Chinese company fairly, regardless of whether it is publicly traded, state-owned or private, and can carry out a transparent, predictable review," said Yao Jian, Chinese Ministry of Commerce spokesman. Yao added that past US political obstructions to Chinese deals had "affected bilateral cooperation to a certain extent." Many US politicians are concerned that Huawei may have links with the Chinese government and military. The company denies any such links, and has referred the CFIUS decision to President Barack Obama, who has final say on the ruling.
