After the incident, caretaker Solomon Islands Prime Minister Rick Hou threatened to blacklist the companies involved in the oil leak near a UNESCO World Heritage site.

"My government is prepared to go as far as putting the companies on a black list internationally if they do not take on their responsibilities," he said at a media conference, as quoted by the ABC news outlet.
Rick Hou earlier asked for Australia's assistance to clean up the oil spill, which he described as causing "irreversible damage".
Recently, the bulk carrier's Hong Kong owner, King Trader Ltd, and the vessel's South Korean insurer issued an apology over the disastrous oil spill.
East Renell is the largest coral atoll in the world, and in 2013 it was designated by UNESCO as a World Heritage Site at risk.
