The Samoa First Party announced the policy last week, outraging some in the country's sizeable Chinese community.
Its deputy leader told local media he wanted to "repatriate" the Chinese out of Samoa, comments which were later withdrawn.
Party leader Unasa Iuni Sapolu says the official policy is to ban all Chinese migrants but she insists the party isn't racist.
"We must put Samoans as a priority. We can't held against ... once the Chinese come over they bring over the products, they are from a bigger, much bigger, billions and billions of population," she said.
