What Happened?
The Solomon Islands, a Pacific nation that sits astride key sea lines of communication between the U.S. and Australia, has a new prime minister who plans to review a 2022 security agreement with China and says the country is looking to the U.S. as well. The Congressional Research Service (CRS), the nonpartisan research arm of Congress, released a report on the Solomon Islands on June 29 outlining that strategic competition.
The island nation sits roughly 2,000 miles northeast of Australia, near U.S. military installations including Army Garrison Kwajalein and Guam. Solomon Islands switched its diplomatic recognition from Taiwan to China in 2019, citing development needs.
Why Does it Matter to Me?
The Solomon Islands' location makes it relevant to how the U.S. military moves people and supplies across the Pacific.
China became the nation's largest trading partner after the 2019 switch and now accounts for roughly 19 percent of total official development financing disbursements there. The U.S. closed its embassy in Honiara in 1993 and did not reopen it until 2023, leaving a 30-year gap in direct diplomatic presence.
In fiscal year 2024, the U.S. obligated $4.4 million in foreign assistance to the Solomon Islands. Australia, by comparison, is estimated to deliver $170.9 million in official development aid between 2026 and 2027.
Both Sides, Now
The new prime minister, Matthew Wale, has criticized the 2022 security agreement his country signed with China and announced plans to review it, though he cannot legally release its text publicly. Wale has pledged to negotiate a comprehensive strategic treaty with Australia and said Solomon Islands would be "looking to the U.S. as well," following a recently signed Development Finance Corporation investment agreement.
Those concerned about the China security pact point to documented expansions of Chinese security involvement. According to the National Bureau of Asian Research (NBR), China deployed a nine-person police liaison team to the Solomon Islands despite an earlier restriction on sending an armed security detachment. Australia publicly expressed deep disappointment when the Solomon Islands and China announced they had signed the agreement in 2022.
The Solomon Islands switched diplomatic recognition from Taiwan to China in 2019, citing development needs, and regional experts have found no current evidence of a China-linked military base or dual-use facility being developed there. China remains the country's largest trading partner, giving Beijing continued economic leverage regardless of the new government's diplomatic direction.
What Happens Next?
Wale has announced plans to review the 2022 China security agreement, but he cannot legally release its text publicly. Analysts at the Center for Strategic and International Studies (CSIS) describe the September 2026 White House summit between President Trump and Xi Jinping as heavy on symbolism but light on substance, with contributors warning that the U.S.-China truce remains fragile.
The U.S. role will depend in part on whether Congress and the administration increase foreign assistance beyond the current $4.4 million annual level. No legislation or funding increase has been announced.
Will the new government's pivot toward the U.S. and Australia be enough to reshape the Solomon Islands' economic and security ties with China?
