In an impassioned speech to parliament, Prime Minister Manasseh Sogavare offered little detail on the shape of the final deal beyond saying that there was "no intention whatsoever... to ask China to build a military base in the Solomon Islands".
He dismissed reports in the Australian media that his country was being "pressured by the People's Republic of China to build a military base in Solomon Islands".
"Where does that nonsense come from? The security treaty... is pursued at the request of the Solomon Islands' government," he said.
"We are not pressured. We are not pressured in any way by our new friends."
A draft version of the agreement, leaked last week, sent shockwaves through Canberra because it included proposals that would allow Chinese security and naval deployments to the Pacific island nation.
Asked in parliament about the status of the deal, Sogavare said: "We will finalise and finish now. The document is ready for signing."
Australian Prime Minister Scott Morrison this week said reports of the deal were "a reminder of the constant pressure and threats that present in our region to our own national security".
Morrison said he had been in contact with New Zealand Prime Minister Jacinda Ardern, who this week called the draft deal "gravely concerning" and said there was "very little reason in terms of the Pacific security for such a need and such a presence".
