Solomons Islands police have extended security surveillance at the border between the eastern province of Temotu and Vanuatu.
The police commissioner, John Lansley, says they have posted an officer in Temotu's provincial capital, Lata, to keep an eye out for criminals crossing the Vanuatu border.
He says it's the first time the Royal Solomon Islands Police has assigned an officer to monitor possibly illegal activity on the eastern border.
He says they had been concentrating on providing security surveillance at the border between Western and Choiseul provinces and Papua New Guinea's Bougainville.
He says there are frequent illegal border crossings from Bougainville into the Solomons.
Mr Langsley also says there is a need for improved border management that includes customs and immigration officials.
