.中國 is a ccTLD launched much earlier than the new Chinese IDN extensions, which came onto the market after 2013.

The birth year of .中國 cannot be pinpointed precisely. In 2000, the Chinese Domain Name Consortium (CDNC) was formed to promote Chinese character-based domains. Registration of .中國 domains probably started in this same year, as evident in the registration dates of domains such as 阿里巴巴.中國 (Alibaba.china IDN) and 亞馬遜.中國 (Amazon.china IDN). Technical details were worked on and improved in subsequent years while such domains could be registered within China. In 2010, .中國 was officially approved by ICANN and added to the Domain Name System for global use.

Below is a chart of the total domains under management of the extension based on data compiled from China Internet Network Information Center (CNNIC) reports.

The first 10 brands from the Top 100 Chinese Internet Companies list compiled from the 2020 Research Report on the Comprehensive Strength of Chinese Internet Companies (2020年中國互聯(lián)網(wǎng)企業(yè)綜合實力研究報告) and then checked their .中國 sites. The result is shown below.
