The location of the town was moved several times, so when it was made a district in the thesaphiban administrative reforms at the beginning of the 20th century, the district office was in present-day Na Thawi.

[1] In 1924 the name was changed back to Chana by the government to avoid confusion with the district Ban Na in Surat Thani Province and Ban Na in Nakhon Nayok Province.

Local people, noting the environmental issues created by the Eastern Economic Corridor, are mobilising to stop the project.

[3] A parallel effort, also (confusingly) called the "Southern Economic Corridor", but not involving Songkhla Province, aims at development of high-speed rail linking Bangkok to Surat Thani province, a double-track rail link from Chumphon to Ranong, a deep-sea Ranong port, and a "Royal Coast" tourism cluster, involving Phetchaburi, Prachuap Khiri Khan, Chumphon, and Ranong provinces.

[4] Chana is divided into 14 sub-districts (tambons), which are further subdivided into 139 administrative villages (mubans).
