China’s internet policy has once again come into the spotlight of the international community. According to reports, the well-known censorship system called the “Great Firewall of China” has fully blocked the operation of TCP port 443, considered critical for the country’s entire internet traffic. Through this port, most international websites, social networks, and online services had been functioning.
As a result of this decision, China’s segment of the internet has become almost entirely isolated from the global network. In other words, only local platforms and government-approved services can continue to operate within the country. This is regarded as real isolation on a continental scale.
Experts emphasize that China’s internet restriction policy is characterized by a “selective blocking” strategy. Instead of shutting everything down, only parts directed toward foreign resources are blocked. This way, domestic digital services and applications keep functioning, while citizens are forced to rely on the national network under government supervision.
Some observers have already begun calling this development a “new digital iron curtain.” This is because Beijing is now strictly controlling the flow of external information and gradually cutting off its own segment from the global internet.
