EAST followed China's first superconducting tokamak device, dubbed [[HT-7]], built by the Institute of Plasma Physics in partnership with [[Russia]] in the early 1990s.{{fact|date=September 2021}}
 
The project was proposed{{by whom?|date=September 2021}} in 1996 and approved in 1998. According to a 2003 schedule,<ref>[http://202.127.205.62/IAC/disk/Design%20of%20the%20EAST(HT-7U) Project/6.doc] {{dead link|date=February 2016}}</ref> buildings and site facilities were to be constructed by 2003. Tokamak assembly was to take place from 2003 through 2005.
 
Construction was completed in March 2006 and on September 28, 2006, "first plasma" was achieved.<ref name=first-plasma>{{cite web|url=http://www.china.org.cn/english/2006/Sep/182561.htm |title=China's New Thermonuclear Fusion Reactor Test Successful |publisher=[[China Internet Information Center|China.org.net]] |date=September 29, 2006}}</ref>

On December 30, 2021, a long-pulse high-parameter plasma operation of 1056 seconds was realized, which once again created a new world record for the operation of the Tokamak experimental device.<ref>{{Citation|title=GLOBALink {{!}} 中国ちゅうごく"人造じんぞうふとし阳"实现千秒级等离子体运行|url=http://www.news.cn/politics/2021-12/31/c_1128221002.htm|language=en|access-date=2021-12-31}}</ref><ref>{{cite web|url=http://english.ipp.cas.cn/news/202112/t20211231_295486.html|title=1,056 Seconds, another world record for EAST|date=December 31, 2021}}</ref>
