Motorola reportedly turned down a US$1.3 billion ($1.4 billion) offer by Huawei Technologies for its mobile infrastructure business prior to selling its business to Nokia Siemens Networks, fearing that regulators would not approve the deal.

Nokia Siemens Networks agreed to acquire Motorola's GSM, 3G and 4G infrastructure business for US$1.2 billion on 19 July.
According to a report by Bloomberg, Motorola was concerned that a deal with Huawei might be rejected by the US Committee on Foreign Investment.
The legacy of Huawei's chief executive officer - Ren Zhengfei's - a former officer within China's People's Liberation Army - has fuelled allegations that the company has ties to the Chinese military.
Huawei has repeatedly denied those allegations. Bloomberg reported that Huawei hired Morgan Stanley and several US law firms to facilitate the US take-over.
