Virtually no chance Canadian and US governments would allow the deal to happen
Chinese computer manufacturer Lenovo has reportedly signed a non-disclosure agreement with BlackBerry as it gears up to bid on a possible purchase of BlackBerry. The real oddity of Lenovo gearing up to bid on BlackBerry is that it has virtually no chance to actually make the purchase. Authorities in the US and Canada would likely block any sale of BlackBerry to a company that you could be potentially controlled by the Chinese government.
Lenovo does have some indirect ties to the Chinese government. Forbes figures the reason Lenovo is trying to make a bit all is so officials of the Chinese government can destroy BlackBerry just as they did with Nortel Networks previously. Nortel was reportedly repeatedly hacked by Chinese at the point that the Chinese were able to under bid Nortel at every turn.
Analysts believe that BlackBerry is the one phone Chinese hackers have been unable to crack and therefore they are not believed to have been able to penetrate internal BlackBerry networks. If by some fluke Lenovo was able to purchase BlackBerry, it would potentially give the Chinese government access to everything they need to hack BlackBerry networks.
