Hồ Chí minh did not say that. The quote "it better to sniff some French/American shit now then eat Chinese rice later" come from an anti China/pro west faction in Viet Nam. They are attempt to create a division between China and Việt Nam relationship by usually create made-up stories every week like how the Chinese are killing Vietnamese fishermen, kidnapping Vietnamese women or the CCP are trying to colonize Việt Nam.
You need to understand these faction are extremely hate VCP and CPC, very pro US to the point they look like a cult. While there is animosity among the Vietnamese toward Chinese but remember these faction are using this animosity to try to create a conflict with China. Despite they are Vietnamese themselves but they are not pro Việt Nam by any mean but have a West worship mentality that communism is bad and everything in the West is good.
