The Legislature finds and declares all of the following:
(a) Finding adoptive families for children, for whom state assistance is desirable pursuant to Chapter 2.1 (commencing with Section 16115), and assuring the protection of the interests of the children affected during the entire assistance period, require special measures when the adoptive parents move to other states or are residents of another state.
(b) Provision of medical and other necessary services for children, with state assistance, encounters special difficulties when the provision of services takes place in other states.
