French Indochina was designated as a (colony of economic exploitation) by the French government. Funding for the colonial government came by means of taxes on locals and the French government established a near monopoly on the trade of opium, salt and rice alcohol. The French administration established quotas of consumption for each Vietnamese village, thereby compelling villagers to purchase and consume set amounts of these monopolised goods. The trade of those three products formed about 44% of the colonial government's budget in 1920 but declined to 20% by 1930 as the colony began to economically diversify.
