In the early 17th century, the Territory probably lay along the Mopan River in the eastern Petén Basin and neighbouring portions of western Belize, being thereby situated east of the Itza of Nojpetén, south of the Yaxhá and Sacnab lakes, and west of Tipuj.

This was equivalent to the Mopan term tulum ki, meaning "wall of agave", which was the name of the Chinamita capital.

[1] Spanish chronicler Juan de Villagutierre Soto-Mayor described the Chinamitas and Tulunquies as two distinct peoples; however, chinamitl is merely the Nahuatl translation of the Mayan tulum ki.

[2] Itza–Chinamita relations were quite strained, as the former "waged incessant wars against" the latter,[6] while the Chinamitas were reciprocally hostile towards their Itza neighbours and their allies.

[9] As of 2009, the Territory and its residents remained "virtually unknown materially and geopolitically except for documentary references or linguistic reconstructions.
