Cuba became one of the world's largest sugarcane producers after the Haitian Revolution and continued to import enslaved Africans long after the practice was outlawed for Spanish citizens in 1817. Cuba did not stop participating in the Atlantic slave trade until 1867, and slavery on the island was not abolished by Spain until 1886. Due to growing pressure to stop the Cuban slave trade throughout the 19th century, more than 100,000 Chinese indentured workers were imported to Cuba to replace dwindling African labor.[citation needed] During the 19th century, Cuban slavery was revitalized by French, Spanish and American expatriates, many of whom moved to Cuba either due to the growing importance of the island's plantation economy or the gradual abolishment of slavery elsewhere.
