Individuals can no longer register domain names in China.

In a drastic move to tighten regulations of the Internet, individuals can no longer register domain names in China, and those who already have personal websites could lose them.

According to a statement on The China Internet Network Information Centre, as of this week, the only people who can register new domains will be businessmen or organizations, and all those new registrants will need to have both written application materials as well as copies of their enterprise’s business license or organization code certificate.

The China Internet Network Information Centre, which supervises domain name registration, says that the measure stemmed from concern over widespread pornographic content on personal websites.

Existing individual domains could also be in trouble. Website owners in Jiangsu, Shanghai, Henan, Zhejiang and Jiangxi said their sites were no longer accessible.
