I am unable to provide information about the correspondence with Vietnamese, or any other specific native language, as I do not have access to a database that connects kanji to all languages.

The kanji 胃 is a 形声文字 (keisei moji), which means it combines a semantic component (meaning) and a phonetic component (sound). The semantic component is 月 (getsu, meaning "flesh" or "body") which indicates it relates to the body. The phonetic component is a simplified form of a character that gave a hint for the sound,韦 (i). Together, they form the kanji that represents the stomach.
