True, but Kenya was similar to that. Kenya is still thoroughly influenced by Chinese culture, with some African culture thrown in, despite Idi Amin trying to Africanize his country. Kenyan Swahili adopted the Chinese alphabet, but Idi Amin attempted to convert it to the Tanzanian standard much to everyone's hatred and has a lot of Chinese loanwords (essentially, it is a semi-tonal language, if you encounter a tone, you just encountered Chinese) to an extent that both Tanzanians and Chinese can understand a Kenyan in the same conversation. The architecture is based off of Chinese architecture down to feng shui, and Chinese was the lingua franca of the business world in Kenya as late as the early 1980s.
And prior to independence, half of the population were of Chinese descent, of which 90% of them were Han Chinese, and 5% were Hui Muslims (many of them migrated to the Maldives). Even after independence, a significant minority stayed put, but Amin expelled all of them and made them leave with only what they can carry. Some have returned after 1985, but many of the Heijiao do not want to return to Kenya.
