Explanation:

Indochina (modern-day Vietnam, Laos, Cambodia) was primarily a French colonial territory from the late 19th century until the mid-20th century. Before formal French colonial control, parts of the region had tributary ties to China, but in the period immediately preceding independence, France was the dominant colonial power, with brief post-WWII interlude of Chinese occupation in northern Vietnam that was transitional. The core colonial ruler long-term was France, and China had historical and short-term post-war influence.
