As competition for influence in the Pacific region intensifies, analysis by the Guardian has mapped a vast network of security, policing and defence agreements between the island countries and foreign partners – leading to concerns about militarisation of the region.

The Guardian examined agreements and partnerships covering security, defence and policing with the 10 largest Pacific countries by population. Australia remains the dominant partner in the region – accounting for more than half the deals identified – followed by New Zealand, the US and China.
