Perhaps or, depends. The only foreseeable salvers would be Chinese linked and The Solomons is politically cosey at this time with the PRC -'Belt and Road' etc, with a lot of Chinese funded infrastucture (and policing), so they have influence in policy and what they want as repayment. Whether the Melanesian's would ever allow though anyone to desecrate Iron Bottom Sound is probably unlikely because they are aware of the sacrifice and significance of the site as a war grave and respect it for that and the important place in history it allows them, and they don't have disdain for the West like the Indonesians. Not all Melanesians are on board with the PRC.
