The Chinese government reported to the world (we don’t know if they also let their own citizens know of course) that they would be creating a centralized threat database.
In essence, this means that anyone in China, whether they are an individual or a company, must as from now reporting a cyberattack.
Any incident involving Trojan malware, hardware vulnerabilities, and content linked to “malicious” IP addresses has to be reported to the Chinese Communist Party Threat Database.
This law is the latest measure taken by the Chinese government to try and control its young population keen on discovering and learning all it can about what is going on in the world. With 1.4 billion people, China is finding controlling internet access one of the toughest measures it has to keep up with.
Whereas limiting usage of a physical passport of controlling it’s country borders could in the past always be done through the sheer size of its armed and police forces, China is finding it harder and harder to adapt to the ever increasing skills of its millennials who keep finding ways to circumvent the strict rules and regulations that the Chinese government has imposed on its own citizens.
The strictest rule is of course for any search on the internet in China relating to the Tiananmen Square massacre or the occupation of Tibet, both events that China claims never happened or if they did, should not be mentioned as such.
The internet censorship in China is very extreme because of a wide variety of laws and administrative regulations. Every year the Chinese government adds more and more rules.
The list of blocked websites in China is very long. For this reason, local Chinese businesses such as Baidu, Tencent, and Alibaba are allowed whilst their foreign rivals can simply not be seen.
For example, since May 2015, Chinese Wikipedia has been blocked in China
As to Google, they are operating in China from Hong Kong, which has different rules and were criticized by the Chinese government for deciding that they would no longer comply with the censor searches in China.
