Adoptive means related through adoption rather than by birth. Adoptive parents, his adoptive country, an adoptive family.
The distinction is careful: adoptive describes the parent and adopted the child, so adoptive parents raise an adopted son. Of a country it means one somebody made their own rather than was born in.
