A leaked draft of a security pact between the two sides contains a provision that would allow Chinese naval deployments to the island nation, which is less than 2,000 kilometres (1,200 miles) from Australia.
China has said it has "no intention at all" to build a military base in the Solomon Islands, dismissing speculation about the purpose of its recent security pact with the island state.
Chinese Foreign Minister Wang Yi, who was in Honiara at the start of an extensive tour of Pacific island states, said on Thursday the agreement Beijing sealed last month was "above board, with honesty and integrity".
A leaked draft of the security agreement — the final version has not been made public — contained a provision that would allow Chinese naval deployments to the island nation, which lies less than 2,000 kilometres (1,200 miles) from Australia.
"It is not imposed on anyone, nor is it targeted at any third party. There is no intention at all to establish a military base," Wang told a news conference after meeting with Solomon Islands' Foreign Minister Jeremiah Manele.
The security pact helps the Solomon Islands to safeguard stability and long-term security, Wang said, "in light of the needs and requests by the Solomon Islands to carry out law enforcement and security cooperation".
It also entails "capacity building" for the police force, the Chinese minister said.
'Not the backyard of anyone'
Australia's former government, toppled in May 21 elections, had said that any move to create a Chinese military base would amount to crossing a "red line", without specifying the consequences.
But Wang countered: "China's cooperation with Pacific Island countries does not target any country and should not be interfered or disrupted by any other country."
He also took a swipe at previous Australian governments describing the Pacific islands as being in the country's "backyard".
"They are not the backyard of anyone. All the Pacific Island countries are entitled to make their own choice instead of being just mere followers of others," the foreign minister said through a translator.
Wang appeared to extend an olive branch to other Pacific powers, though, saying China respected existing international relationships with Pacific island countries and would explore joining three-way partnerships with them.
Last November, protests against Prime Minister Manasseh Sogavare's rule flared into riots in the capital Honiara, during which much of the city's Chinatown was torched.
The unrest "gravely threatened the life and property of the Chinese community in this country", Wang said.
China sent anti-riot equipment and an "ad-hoc police advisory group" at the request of Honiara, he said, as well as sealing the security agreement.
It aimed to build Solomon Islands' law enforcement capacity and safeguard its security, he said and "at the same time, more effectively protect the Chinese nationals and institutions".
