China's Foreign Minister says China has "no intention at all" of building a military base in Solomon Islands.
Wang Yi, who has been in Honiara as part of a tour of Pacific Island states, said the security agreement Beijing sealed last month with the Manasseh Sogavare government was "above board, with honesty and integrity".
A leaked draft of the security agreement contains a provision that would allow Chinese naval deployments to the Solomons.
At a news conference in Honiara following his meeting with the Solomons foreign minister Jeremiah Manele, Wang said the agreement has not been imposed on anyone, nor is it targeted at any third party.
Wang also said China respected existing international relationships with Pacific countries and would explore joining three-way partnerships with them.
Australia's former government, toppled in 21 May elections, had said that any move to create a Chinese military base would amount to crossing a "red line" without specifying the consequences.
New Zealand and the United States have also expressed concern about the security arrangement between China and Honiara.
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 which described 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," he said.
"Any smears and attacks on the normal security cooperation between China and Solomon Islands are not above the board and any such disruption will not get anywhere."
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.
The security pact helps the Solomon Islands government to safeguard stability and long term security, he 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.
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".
