general secretary (Workers' Party of Korea or Communist Party of Vietnam)
Rare term; used specifically for the top party post in North Korea and Vietnam. Compare 総書記 and 書記長, which are more common for other communist parties.
The general secretary of North Korea is Kim Jong-un.
The general secretary of the Communist Party of Vietnam is the party's top leader.
Often used for chief secretary or secretary-general in non-communist contexts, or historically for some communist parties. 総秘書 is a distinct, rarer title.
Compound of 総 (general, overall) and 秘書 (secretary). The exact historical derivation is uncertain; the term appears to be a calque or adaptation used in Japanese for the top party positions in North Korea and Vietnam.
