1. Vietnam: French colonization of Vietnam lasted from the mid-19th century to the mid-20th century. During this time, French became the language of administration, education, and commerce. While Vietnamese is the official language, French is still spoken by some, particularly in older generations and in specific professional circles.
2. Laos: Similar to Vietnam, Laos was a French protectorate from the late 19th century to the mid-20th century. French influence is less prevalent than in Vietnam, but it is still found in some government and educational settings, and a small percentage of the population speaks French.
It's worth noting that French influence in both countries has diminished since independence, but it still plays a role in their cultural and linguistic landscapes.
