(two definitions: I and II; in I: "This province formerly gave its name to the whole kingdom")
(b) Definition II is what Wikipedia terms Cochinchina.
Cochinchina
http://en.wikipedia.org/wiki/Cochinchina
(the southern third of Vietnam; In Vietnamese, the region is called Nam Bộ 南部; "The name 'Cochin' derives from the Malay Kuchi which referred to all of Vietnam. This term was in turn derived from the Chinese jiao zhi 交趾, pronounced giao chỉ in Vietnam. 'Cochinchina' derives from the need or desire to distinguish this Cochi/Kochi/Kuchi from the city (and princely state) of Kochi in India")
(c) 南沙群岛 in Chinese / Truong Sa 長沙 in Vietnamese
(i) Spratly Islands
http://en.wikipedia.org/wiki/Spratly_Islands
("The islands were sporadically visited throughout the nineteenth and early twentieth centuries by mariners from different European powers (including Richard Spratly, after whom the island group derives its most recognizable English name). However, these nations showed little interest in the islands. In 1883, German boats surveyed the Spratly and Paracel Islands but withdrew the survey eventually after receiving protests from the Nguyễn Dynasty. Many European maps before the 20th century do not even make mention of this region")
