Softbank buys its mobile-phone network gear from Chinese companies which have been viewed as security threats by the United States and the relationship may become an issue as regulators review its bid for Sprint Nextel.

It is likely that US officials will address those links when they scrutinise the deal, he said.
The House Intelligence Committee in a report last month urged US companies to steer clear of Huawei and ZTE, citing concerns that the Chinese government could install malicious hardware or software in US telecommunications networks.
"The flap over Huawei and ZTE means that at a minimum, the extent to which equipment from Huawei and ZTE would be introduced into the US infrastructure will be an issue," said Baker, a partner with Steptoe & Johnson in Washington.
"This deal will probably end up getting approved but with a very detailed national security agreement."
