>> China cementing an iron grip on its Internet Monday, adopting a new controversial cybersecurity law. The rules require tech firms to store important data on servers in China, and provide quote technical support for Chinese security agencies. Officials say it's meant to fight growing threats like hacking and terrorism.
But as Catherine Cadell reports, overseas critics say it could pave the way for a crackdown.>> I think the big issue is that the wording of the law is incredibly vague. So that's what business groups are worried about, and rights groups as well. Is that not so much what will immediately happen, but what could potentially happen in the future.
One of the things people particularly worried about is that under this law, they can potentially have access to encryption keys. They could potentially require companies to make back door in the software which would give them access the law itself. Criminalizes pretty much anything that works against, I think the quote they used was national unity.
That's such an incredibly vague wording for a law and I think that's what has companies most concerned.>> Critics say the new law puts foreign business in an awkward position. Open themselves up to potential meddling by state authorities or risk losing business in the world's second largest economy.
>> It also solidifies an uncertain business environment that these companies have all ready been working on this for the last few years. As we see new companies from the US or from elsewhere entering the Chinese market, Beijing is continuing to push what some people would call a protection as view over local technology.
>> Expert say aspects of the law have been in place for awhile, but setting them in stone is part of a broader crackdown under Chinese president Xi Jinping. One that critics say sets up new targets beyond lawyers and journalists snuffing out cyber-dissent.
