The Solomon Islands prime minister, Manasseh Sogavare, has made an official complaint to the Special Coordinator of the Regional Assistance Mission to Solomon Islands, Timothy George, on a range of issues.
Mr Sogavare says some people have entered the country under the pretext of being with RAMSI and are living in Solomon Islands illegally.
Mr Sogavare also says spouses of RAMSI personnel are working in the country illegally.
This comes after the prime minister alleged incidents of prostitution involving RAMSI personnel and local women.
RAMSI has rejected the allegations, saying there is no evidence.
Mr Sogavare has forwarded a complaint to the police commissioner and the police minister, saying he was acting amid public concern of RAMSI personnel not following the law.
