Solomon Islands PM Tests China Pact With Surprise Security Review and New Deal Plan With Australia

The Solomon Islands’ prime minister has ordered a review of his country’s controversial security agreement with China and signaled plans for a new pact with Australia. For Pacific islanders, Canberra, Beijing, and Washington, the move could reshape who guarantees security — and wields influence — in one of the most contested stretches of ocean on the planet.

The Solomon Islands, a small archipelago that has become a big piece on the Indo-Pacific chessboard, is again recalibrating its security loyalties. Prime Ministerial statements on 3 June that the government will review its security pact with China and pursue a new agreement with Australia suggest that Honiara is testing how far it can rebalance between Beijing and Canberra without losing leverage with either.

The Solomon Islands’ prime minister announced that his government will conduct a review of the existing security agreement with China, a deal that triggered alarm in Australia, the United States, and other Pacific neighbours when it was signed. At the same time, he revealed plans for a new security agreement with Australia, the country’s traditional security partner and largest aid donor. Details of the proposed Australian pact have yet to be published, but the intention to negotiate it while reassessing the China deal signals a significant shift in posture.

For Solomon Islanders, the stakes are not abstract. Security agreements determine who shows up when unrest breaks out in Honiara’s streets, whose vessels patrol their waters, and which foreign officers work alongside their police. A tilt too heavily toward one external backer can deepen domestic polarisation, especially in a country that has seen patterns of internal tension and riots. Communities that depend on Chinese investment, Australian aid, or both are watching closely to see whether a new balance delivers more stability and economic opportunity or simply more outside pressure.

Regionally, the announcement is a test of the competing security visions China and Australia offer Pacific states. Beijing’s pact with the Solomon Islands raised fears in Canberra and Washington that it could eventually open the door to a Chinese naval presence in the South Pacific, close to key sea lanes and Australia’s east coast. Australia, backed by the United States and like-minded partners, has responded by increasing aid, patrols, and high-level visits across the Pacific, stressing “Pacific family” ties and warning against militarisation.

A review of the China pact does not automatically mean its abandonment, but it does give Honiara leverage: by showing readiness to re-engage with Australia on security, the Solomon Islands can extract more from both sides. For China, losing ground in Honiara would be a setback to its broader ambition of building security and infrastructure footholds across the Pacific. For Australia, securing a new agreement would be a tangible win in a region where it has sometimes been accused of taking neighbours for granted.

The United States, which relies on a web of alliances and access agreements across the Indo-Pacific to contain Chinese military reach, has a clear interest in how this plays out. A Solomon Islands that swings firmly back into the orbit of Canberra and its partners would ease some concerns about a Chinese security presence near sea lines connecting the U.S. West Coast, Australia, and key Pacific territories. Conversely, a cosmetic review that leaves the China pact largely intact while adding an Australian layer could entrench a complex dual-dependence that is harder for Washington to shape.

Key Takeaways

Outlook & Way Forward

In the coming months, Honiara will likely seek to turn its dual-track approach into concrete gains: more aid, training, and infrastructure from Australia, and perhaps more favourable economic terms from China, while preserving maximal room for manoeuvre. Domestic politics will matter; opposition figures and civil society groups sceptical of over-reliance on any single external sponsor may push for greater transparency and parliamentary oversight of security deals.

For Australia, the opportunity is clear but delicate. Negotiating a new pact that reassures both Canberra and local communities will require more than security hardware; it will involve commitments on labour mobility, climate resilience, and development that address everyday Solomon Islander concerns. Beijing, meanwhile, may respond with its own outreach and investment offers to demonstrate that it remains a reliable partner.

Beyond these immediate moves, larger questions persist for the region: whether Pacific Island states can leverage strategic competition to their advantage without importing rivalries they cannot control, and whether external powers are willing to treat them as sovereign actors rather than venues for proxy contests. The Solomon Islands’ review of its China pact and courtship of a new Australian agreement will be an early indicator of which way this balance is tipping.
