The Premier of Solomon Islands' Western Province is calling on the Prime Ministers of both the Solomons and Papua New Guinea to tighten border controls, in an effort to prevent guns being trafficked to the Shortland Islands from Bougainville.

George Solingi Lilo says there have been violent standoffs between landowners and logging companies in recent times leading to at least one death.

Prime Minister Manasseh Sogavare, who is also his government's acting Forestry Minister says the ongoing tensions between landowners and logging companies have led to armed conflict and divided communities.

As a result, the Solomon Islands government has cancelled the licences of 30 logging companies in the midst of what Mr Sogavare says is a national security crisis.
