OK, so the UK didn't out and compliment Huawei. Less than a week after British authorities launched a cybersecurity review of the company, however, Prime Minister David Cameron said that British telecommunications company TalkTalk had shown "great leadership" in implementing its online pornography filter.

TalkTalk's filter, you see, is controlled by Huawei, whose UK employees determine which websites TalkTalk will and won't filter.

The UK, like the U.S., Australia and others, has expressed concern that Huawei, founded by a former member of the Chinese military, poses a security threat.
