Khara Khoto appears to be on or near the extension of the 'Gobi Wall' into present day China, presumably as part of the same system.

The name 'Gobi Wall' seems to refer to the section of the wall within Mongolia. Its garrisons and forts are numbered from G01 at the western end of the section, where the wall crosses the border.
